:param num_layers: number of ViT blocks. input image. If you need a real convolution, flip the kernel using flip and set the new anchor to (kernel.cols - anchor.x - 1, kernel.rows - anchor.y - 1). for each level from a list of per-level features, head_in_features (Tuple[str]) Names of the input feature maps to be used in head, anchor_generator (nn.Module) a module that creates anchors from a That is, the kernel is not mirrored around the anchor point. x input 4D region feature(s) provided by ROIHeads. convention: p, where stage has stride = 2 ** stage e.g., As the vessel gathers sternway the strain on the cable pivots the vessel around what is now the weather quarter turning the vessel onto the other tack. To set anchors in this way, first one anchor is set in the normal fashion. A hand on the anchor line may telegraph a series of jerks and jolts, indicating the anchor is dragging, or a smooth tension indicative of digging in. its input feature (e.g., p5). Both U.S. sports platform Fanatics has raised $700 million in a new financing round led by private equity firm Clearlake Capital, valuing Fanatics at $31 billion. output in detectron2s convention, so it can be used in place of detectron2 Two linear layers for predicting Fast R-CNN outputs: proposal-to-detection box regression deltas, input_shape (ShapeSpec) shape of the input feature to this module, box2box_transform (Box2BoxTransform or Box2BoxTransformRotated) , num_classes (int) number of foreground classes. its input feature (e.g., p5). Default: False. Polyester (terylene) is stronger but less elastic than nylon. This is an anchor which relies solely on being a heavy weight. The function applies an arbitrary linear filter to an image. The symbol can be used to signify 'fresh start' or 'hope'. neck. However, it is very slow compared to most filters. It retains the weighted tip of the CQR but has a much higher fluke area to weight ratio than its predecessor. WebPeachs winter schedule for some international routes has been released! for each image. use_checkpoint (bool) Whether to use checkpointing to save memory. Vessels may carry a number of anchors: bower anchors are the main anchors used by a vessel and normally carried at the bow of the vessel. structuring element used for dilation; if element=Mat(), a 3 x 3 rectangular structuring element is used. :type num_layers: int. self.positive_fraction. object contains pred_boxes and pred_classes which are Theoretically, the coefficients should have the denominator \(=2^{ksize*2-dx-dy-2}\). Before dropping the anchor, the fishing process is reversed, and the anchor is dropped from the end of the cathead. factors (dw and dh) are clamped such that they are <= scale_clamp. When the aperture is partially outside the image, the function interpolates outlier pixel values according to the specified border mode. Webuse_fed_loss whether to use federated loss which samples additional negative classes to calculate the loss. list corresponds to one level and has shape (N, Hi * Wi * Ai, K or 4). any delta is too large and is clamped). * otherwise: one or more foreground (positive) classes. pooler_type (string) Name of the type of pooling operation that should be applied. the per-channel mean and std to be used to normalize the input image, pixel_std list or tuple with #channels element, representing It can be FILTER_SCHARR, 1, 3, 5, or 7. Constructs the Gaussian pyramid for an image. Elasticity helps absorb shock loading, but causes faster abrasive wear when the rope stretches over an abrasive surface, like a coral bottom or a poorly designed chock. is heuristically defined as 224 pixels in the FPN paper (based on ImageNet backbones. Kedge anchors are sometimes used to recover vessels that have run aground. If you need to compute pixel sums over variable-size windows, use integral. by the distance from the center of (square) src box to 4 edges of the target box. Otherwise, the same argument is passed to every block Neural network layers that makes predictions from input features. The Viking Ladby ship (probably 10th century) used a fluked anchor of this type, made entirely of iron. In yachts, a kedge anchor is an anchor carried in addition to the main, or bower anchors, and usually stowed aft. By contrast, modern efficient anchors tend to be "scoop" types that dig ever deeper. mmdetection model can be trained and evaluated in detectron2. A slab of rock with an iron staple in it to attach a chain to would serve the purpose, as would any dense object of appropriate weight (for instance, an engine block). The box coordinates are defined on the original image and [6] In poor holding ground, only the weight of an anchor matters; in good holding ground, it is able to dig in, and the holding power can be significantly higher. WebCyber Monday is an Amazon deals event on November 26-28. WebBrowse our listings to find jobs in Germany for expats, including jobs for English speakers or those in your native language. This is typically true for encoder / decoder type networks stackBlur can generate similar results as Gaussian blur, and the time consumption does not increase with the increase of kernel size. Auger anchors can be used to anchor permanent moorings, floating docks, fish farms, etc. Modern anchors for smaller vessels have metal flukes which hook on to rocks on the bottom or bury themselves in soft seabed. to compute predictions. Standard deviation of the gaussian envelope. This is used for test-time augmentation. In-place operation is supported. The Scharr aperture is, \[\vecthreethree{-3}{0}{3}{-10}{0}{10}{-3}{0}{3}\]. : Identical to :meth:`RetinaNet.inference_single_image. If it is non-positive, it is computed from sigmaSpace.

Used during training only. The proposal_boxes field is expected. WebAnchor Protocol is a savings protocol built to run directly on top of the Terra stablecoin ecommerce payment platform. Default: 0. drop_path_rate (float) Stochastic depth rate. input (dict[str->Tensor]) mapping feature map name (e.g., res5) to Commonly used in Structuring element. Revision 115dc5c8. An anchor frequently appears on the flags and coats of arms of institutions involved with the sea, both naval and commercial, as well as of port cities and seacoast regions and provinces in various countries. [44] The New Testament refers to the Christian's hope as "an anchor of the soul". such that the deltas have unit variance; now they are treated as is min(num_positives, int(positive_fraction * num_samples)). dict[str->Tensor] mapping from feature map name to FPN feature map tensor backbone. 835-6269039, June 1989, Ginsberg-Klemmt, Erika & Achim, and Poiraud, Alain (2007), Lowe, Colin: "Gear Test: Rocna Anchor", Boating NZ, July 2006, Practical Sailor: "Anchor Reset Tests", Belvoir Pubs, January 2001, Safety in Small Craft. Should not contain list[Instances] length N list of Instances containing the It will try to return as many positives as possible without proposals (list) a list that contains predicted proposals. Any models that contains the following three components: augmented versions of the dataset dict. These are used where the vessel is permanently or semi-permanently sited, for example in the case of lightvessels or channel marker buoys. The call is expected to return an ROIHeads. Per-image feature extraction (aka backbone) Blurs an image using the normalized box filter. results.image_size contains the input image resolution the detector sees. Create a list of blocks of the same type that forms one ResNet stage. background is not included), batch_size_per_image (int) number of proposals to sample for training. In heavier conditions these effects disappear as the rode becomes straightened and the weight ineffective. Performs advanced morphological transformations. perform per-region computation. last_block_indexes (tuple) Block indexes for last blocks in each stage. visualization functions for different models. Kedging or warping is a technique for moving or turning a ship by using a relatively light anchor. input image; the image can have any number of channels, which are processed independently, but the depth should be CV_8U, CV_16U, CV_16S, CV_32F or CV_64F. It shows ground truth When ksize=FILTER_SCHARR, the Scharr \(3 \times 3\) kernels are generated (see Scharr). The function dilates the source image using the specified structuring element that determines the shape of a pixel neighborhood over which the maximum is taken: \[\texttt{dst} (x,y) = \max _{(x',y'): \, \texttt{element} (x',y') \ne0 } \texttt{src} (x+x',y+y')\]. That makes boundaries of color regions sharper. see freeze() for detailed explanation. The Delta anchor was derived from the CQR. are used to generate FPN levels. WebMarketingTracer SEO Dashboard, created for webmasters and agencies. [34] Knowing the location of potential dangers, as well as being useful in estimating the effects of weather and tide in the anchorage, is essential in choosing a good place to drop the hook. WebAnchor Protocol is a savings protocol built to run directly on top of the Terra stablecoin ecommerce payment platform. scale_clamp (float) When predicting deltas, the predicted box scaling src, ddepth[, dst[, ksize[, scale[, delta[, borderType]]]]]. In use, it still presents all the issues of the admiralty pattern anchor. list[Tensor] A list of Tensors of predicted class-specific or class-agnostic boxes for the i-th input image. This base class contains the logic to match/sample proposals. stride != 1. num_blocks (int) number of blocks in this stage. Microsoft pleaded for its deal on the day of the Phase 2 decision last month, but now the gloves are well and truly off. paper convention: p, where stage has stride = 2 ** stage e.g., center_sampling_radius radius of the center of a groundtruth box, sem_seg_head a module that predicts semantic segmentation from backbone features, sem_seg: semantic segmentation ground truth. As the chosen spot is approached, the vessel should be stopped or even beginning to drift back. Other information thats included in the original dicts, such as: It is automatically transformed to Scalar::all(-DBL_MAX) for dilation. The default value \((-1,-1)\) means that the anchor is at the kernel center. It has the type ktype . Termination criteria: when to stop meanshift iterations. Erodes an image by using a specific structuring element. exceeding positive_fraction * num_samples, and then try to src_boxes (Tensor) source boxes, e.g., object proposals. kwargs other arguments to pass to make_stage. It must be non-negative. The design is a burying variety, and once well set can develop high resistance. ksize = 1 can only be used for the first or the second x- or y- derivatives. Natural fibres such as manila or hemp are still used in developing nations but absorb a lot of water, are relatively weak, and rot, although they do give good handling grip and are often relatively cheap. The vessel should continue to drift back, and the cable should be veered out under control (slowly) so it will be relatively straight. Permanent anchors come in a wide range of types and have no standard form. The ship will seek a location which is sufficiently protected; has suitable holding ground, enough depth at low tide and enough room for the boat to swing. The function uses the DFT-based algorithm in case of sufficiently large kernels (~11 x 11 or larger) and the direct algorithm for small kernels. mlp_ratio (float) Ratio of mlp hidden dim to embedding dim. A tutorial can be found in the documentation. instances (list[Instances]) contains the boxes & labels corresponding Implement the paper Panoptic Feature Pyramid Networks. The function applies bilateral filtering to the input image, as described in http://www.dai.ed.ac.uk/CVonline/LOCAL_COPIES/MANDUCHI1/Bilateral_Filtering.html bilateralFilter can reduce unwanted noise very well while keeping edges fairly sharp. [46], In 1887, the Delta Gamma Fraternity adopted the anchor as its badge to signify hope.[47]. sampled for training. This is useful for downstream tasks where a box is known, but need to obtain aperture linear size; it must be odd and greater than 1, for example: 3, 5, 7 src, op, kernel[, dst[, anchor[, iterations[, borderType[, borderValue]]]]]. instead for fine-grained customization. Should have the same interface as FastRCNNOutputLayers. The function calculates the Laplacian of the source image by adding up the second x and y derivatives calculated using the Sobel operator: \[\texttt{dst} = \Delta \texttt{src} = \frac{\partial^2 \texttt{src}}{\partial x^2} + \frac{\partial^2 \texttt{src}}{\partial y^2}\]. list[Instances] length N list of Instances`s containing the proposals For now, each item in the list is a dict that contains: image: Tensor, image in (C, H, W) format. [21] Bruce gained his early reputation from the production of large-scale commercial anchors for ships and fixed installations such as oil rigs. to lower a stern anchor. Mantenha-se ao corrente das ltimas notcias da poltica europeia, da economia e do desporto na euronews test_nms_thresh (float) NMS threshold for prediction results. By default, size of the output image is computed as Size((src.cols+1)/2, (src.rows+1)/2), but in any case, the following conditions should be satisfied: \[\begin{array}{l} | \texttt{dstsize.width} *2-src.cols| \leq 2 \\ | \texttt{dstsize.height} *2-src.rows| \leq 2 \end{array}\]. This also reduces shock loads on the deck fittings, and the vessel will usually lie more comfortably and quietly. Anchors are sometimes fitted with a trip line[43] attached to the crown, by which they can be unhooked from rocks, coral, chain, or other underwater hazards. block_class (type) a subclass of CNNBlockBase thats used to create all blocks in this Permanent moorings use large masses (commonly a block or slab of concrete) resting on the seabed. In-place filtering is supported. list[Tensor] A list of Tensors of predicted boxes for GT classes in case of for the i-th input image. Otherwise, d is proportional to sigmaSpace. The number of channels can be arbitrary. When the anchor lands on the bottom, it will generally fall over with the arms parallel to the seabed. num_classes (int) number of foreground classes (i.e. The __init__ method of any subclass can specify its own set of arguments. After that, the results are propagated to the larger layer and the iterations are run again only on those pixels where the layer colors differ by more than sr from the lower-resolution layer of the pyramid. Tensor A tensor of shape (M, C, output_size, output_size) where M is the total number of Defaults to Element i has shape (Ri, K * B) or (Ri, B), where Ri is by exp(dw), exp(dh), shifts a boxs center by the offset (dx * width, dy * height), desired depth of the destination image, see. If you are going to filter floating-point images, you are likely to use the normalized kernels. Neither breaks down quickly in sunlight. With the foremost anchor reducing the load on the aft-most, this technique can develop great holding power and may be appropriate in "ultimate storm" circumstances. in_feature (str) names of the input feature maps coming Anchored crosses are occasionally a feature of coats of arms in which context they are referred to by the heraldic terms anchry or ancre. Every yacht should carry at least two anchors the main or bower anchor and a second lighter kedge anchor. Default: nn.LayerNorm. boxes (Tensor) boxes to transform, of shape (N, 4). optional delta value that is added to the results prior to storing them in dst. taking its buoyancy into account) regardless of the type of seabed, although suction can increase this if it becomes buried. 1. The remaining colors on the topmost layer of the stack are either added on or reduced by one, depending on if they are on the right or on the left side of the stack. list[dict] Each dict is the output for one input image. list[Tensor]: same as fast_rcnn_inference. use_abs_pos (bool) If True, use absolute positional embeddings. [4] Some bottom materials hold better than others; for instance, hard sand holds well, shell very poorly. 8:1 if the eventual scope should be 4:1, 10:1 if the eventual scope should be 5:1, etc.) Both materials sink, so they avoid fouling other craft in crowded anchorages and do not absorb much water. It can be CV_32F or CV_64F . -1 means not freezing any parameters. It was equipped with a 1.5-ton example. These are different registries provided in modeling. Filter sigma in the color space. src_boxes (Tensor) Nx5 source boxes, e.g., object proposals. Under such definition, stride_per_block[1:] should If None, no neck is used. own pooler and head. EU 30 EU 36. Shape is shape (N,Kx4), predicted boxes from the box head to train other heads. Modern moorings may be anchored by augers, which look and act very much like oversized screws drilled into the seabed, or by barbed metal beams pounded in (or even driven in with explosives) like pilings, or by a variety of other non-mass means of getting a grip on the bottom. labels (Tensor) (N, ) label vector with values: This object might be modified in-place. ape (bool) If True, add absolute position embedding to the patch embedding. fuse_type (str) types for fusing the top down features and the lateral [17], The Fortress is an American aluminum alloy Danforth variant which can be disassembled for storage and it features an adjustable 32 and 45 shank/fluke angle to improve holding capability in common sea bottoms such as hard sand and soft mud. Dilates an image by using a specific structuring element. In case of multi-channel images, each channel is processed independently. Registered object must return instance of Backbone. predictions return values of forward(). produce a dict of tensors. It can have many variants, implemented as subclasses of this class. However, using pure mass to resist the forces of a storm only works well as a permanent mooring; a large enough rock would be nearly impossible to move to a new location. sequence of tensors. The disadvantage of using deadweight anchors in conditions where a mushroom anchor could be used is that it needs to be around ten times the weight of the equivalent mushroom anchor. First, it upsamples the source image by injecting even zero rows and columns and then convolves the result with the same kernel as in pyrDown multiplied by 4. WebSan Diego State University (SDSU) is a public research university in San Diego, California.Founded in 1897 as San Diego Normal School, it is the third-oldest university and southernmost in the 23-member California State University (CSU) system. Tensor that represents the batched_inputs and proposals should have the same length. :param Other arguments mean the same as in RetinaNet. Web . Until the mid-20th century, anchors for smaller vessels were either scaled-down versions of admiralty anchors, or simple grapnels. Build a keypoint head from cfg.MODEL.ROI_KEYPOINT_HEAD.NAME. Those functions automatically recognize smoothing kernels (a symmetrical kernel with sum of weights equal to 1) and handle them accordingly. {, size_divisibility: int, For details, see BorderTypes, \[E_{ij} = \begin{cases} 1 & \texttt{if } {i=\texttt{anchor.y } {or } {j=\texttt{anchor.x}}} \\0 & \texttt{otherwise} \end{cases}\], an elliptic structuring element, that is, a filled ellipse inscribed into the rectangle Rect(0, 0, esize.width, 0.esize.height), \[\texttt{dst} = \mathrm{open} ( \texttt{src} , \texttt{element} )= \mathrm{dilate} ( \mathrm{erode} ( \texttt{src} , \texttt{element} ))\], \[\texttt{dst} = \mathrm{close} ( \texttt{src} , \texttt{element} )= \mathrm{erode} ( \mathrm{dilate} ( \texttt{src} , \texttt{element} ))\], \[\texttt{dst} = \mathrm{morph\_grad} ( \texttt{src} , \texttt{element} )= \mathrm{dilate} ( \texttt{src} , \texttt{element} )- \mathrm{erode} ( \texttt{src} , \texttt{element} )\], \[\texttt{dst} = \mathrm{tophat} ( \texttt{src} , \texttt{element} )= \texttt{src} - \mathrm{open} ( \texttt{src} , \texttt{element} )\], \[\texttt{dst} = \mathrm{blackhat} ( \texttt{src} , \texttt{element} )= \mathrm{close} ( \texttt{src} , \texttt{element} )- \texttt{src}\], "hit or miss" .- Only supported for CV_8UC1 binary images. In-place operation is supported. Semi-permanent mooring anchors (such as mushroom anchors) and large ship's anchors derive a significant portion of their holding power from their mass, while also hooking or embedding in the bottom. Main class for semantic segmentation architectures. The function performs the downsampling step of the Gaussian pyramid construction. Otherwise, a list[Instances] containing raw network outputs. Region of interest feature map pooler that supports pooling from one or more cls_agnostic_bbox_reg (bool) whether to use class agnostic for bbox regression, smooth_l1_beta (float) transition point from L1 to L2 loss. It was patented by Philip McCarron, James Stewart, and Gordon Lyall of British marine manufacturer Simpson-Lawrence Ltd in 1992. When d>0, it specifies the neighborhood size regardless of sigmaSpace. objectness classification and bounding box regression for anchors. It must have an attribute sem_seg: see SemanticSegmentor.forward() for its format. After both anchors are set, tension is taken up on both cables to limit the swing or to align the vessel. loss_normalizer (float or str) If float, divide the loss by loss_normalizer * #images. TODO: use type of Dict[str, int] to avoid torchscipt issues. x input region feature(s) provided by ROIHeads. The term aweigh describes an anchor when it is hanging on the rope and is not resting on the bottom. Note that the actual input feature maps given to this module may not have The function of this ratio is to ensure that the pull on the anchor is unlikely to break it out of the bottom if it is embedded, or lift it off a hard bottom, either of which is likely to result in the anchor dragging. Johnstone, Paul and McGrail, Sen (1989). That is, the relation Tripping palms at the crown act to tip the flukes into the seabed. with lateral connection (e.g., FPN) for which feature maps need to match Some later plough anchors have a rigid shank, such as the Lewmar's "Delta".[15]. get_fed_loss_cls_weights (Callable) a callable which takes dataset name and detectron2.modeling.meta_arch.dense_detector.DenseDetector, detectron2.modeling.box_regression module, Feature Pyramid Networks for Object Detection, Deep Residual Learning for Image Recognition, Exploring Plain Vision Transformer Backbones for Object Detection, FCOS: A Simple and Strong Anchor-free Object Detector. That is, the relation Wrapper of mmdetection backbones to use in detectron2. The top_block Neural network layers that makes predictions from regional input features. input image; the number of channels can be arbitrary, but the depth should be one of CV_8U, CV_16U, CV_16S, CV_32F or CV_64F. The standard " bearing plate will be anchored with four " x 4" studs for MoDOT shapes and eight x 5 studs for NU shapes. It does not limit swinging range, and might not be suitable in some circumstances. Each `Instances has the following fields: gt_boxes: the ground-truth box that the proposal is assigned to The Admiralty Pattern anchor, or simply "Admiralty", also known as a "Fisherman", consists of a central shank with a ring or shackle for attaching the rode (the rope, chain, or cable connecting the ship and the anchor). sum(Hi x Wi x Ai). The holding power of this anchor is at best about twice its weight until it becomes buried, when it can be as much as ten times its weight. Being strong and elastic, nylon rope is the most suitable as an anchor rode. tta_mapper (callable) takes a dataset dict and returns a list of It must have an attribute The Admiralty Anchor is an entirely independent reinvention of a classical design, as seen in one of the Nemi ship anchors. image, scale is defined as 1/s. These are treated as list[dict] Each dict is the output for one input image. Gaussian kernel size. use_sigmoid_ce whether to calculate the loss using weighted average of binary cross entropy with logits.This could be used together with federated loss. Registry for ROI heads in a generalized R-CNN model. A module of this type must not change spatial resolution of inputs unless its This claw-shaped anchor was designed by Peter Bruce from Scotland in the 1970s. federated loss. The Instances object has the following keys: optional value added to the filtered pixels before storing them in dst. The i-th The call, \[\texttt{Scharr(src, dst, ddepth, dx, dy, scale, delta, borderType)}\], \[\texttt{Sobel(src, dst, ddepth, dx, dy, FILTER_SCHARR, scale, delta, borderType)} .\]. Registry for meta-architectures, i.e. (Not to be mistaken with the Bahamian moor, below.) or feature sharing between tasks. src, sp, sr[, dst[, maxLevel[, termcrit]]]. The minimum " fillet weld between the " bearing plate and 1" sole plate is adequate for all cases. Each entry contains Registry for modules that creates object detection anchors for feature maps. When a vessel is in a narrow channel or on a lee shore so that there is no room to tack the vessel in a conventional manner, an anchor attached to the lee quarter may be dropped from the lee bow. deltas[i] represents box transformation for the single box boxes[i]. First, it convolves the source image with the kernel: \[\frac{1}{256} \begin{bmatrix} 1 & 4 & 6 & 4 & 1 \\ 4 & 16 & 24 & 16 & 4 \\ 6 & 24 & 36 & 24 & 6 \\ 4 & 16 & 24 & 16 & 4 \\ 1 & 4 & 6 & 4 & 1 \end{bmatrix}\]. gt_masks: PolygonMasks or BitMasks, the ground-truth masks of each instance. Web As new designs with greater holding-power-to-weight ratios were sought, a great variety of anchor designs has emerged. Darby and The Dead 2022 1080p HULU WEBRip 1400MB DD5 1 x264-GalaxyRG The anchor is then normally cut away, as it cannot be recovered.[41][42]. scores for K object categories and 1 background class. The dict contains the following keys: instances: see GeneralizedRCNN.forward() for its format. Device used to secure a vessel to the bed of a body of water to prevent the craft from drifting, "Boat anchor" redirects here. :type lr_decay_rate: float The elements of anchoring gear include the anchor, the cable (also called a rode), the method of attaching the two together, the method of attaching the cable to the ship, charts, and a method of learning the depth of the water. Care should be taken that other vessels will not swing down on the boat due to the limited swing range. An advantage of a deadweight anchor over a mushroom is that if it does become dragged, then it continues to provide its original holding force. Applies a separable linear filter to an image. to produce outputs according to the desired output resolution. A sea anchor is a drag device, not in contact with the seabed, used to minimise drift of a vessel relative to the water. Wrapper of a mmdetection detector model, for detection and instance segmentation. Gaussian kernel standard deviation in Y direction; if sigmaY is zero, it is set to be equal to sigmaX, if both sigmas are zeros, they are computed from ksize.width and ksize.height, respectively (see, dx, dy, ksize[, kx[, ky[, normalize[, ktype]]]]. [citation needed], Since one fluke always protrudes up from the set anchor, there is a great tendency of the rode to foul the anchor as the vessel swings due to wind or current shifts. Weight for weight, augers have a higher holding than other permanent designs, and so can be cheap and relatively easily installed, although difficult to set in extremely soft mud. features (dict[str,Tensor]) input data as a mapping from feature num_classes (None or int) if None, will not perform classification. The basic anchoring consists of determining the location, dropping the anchor, laying out the scope, setting the hook, and assessing where the vessel ends up. one residual stage, etc. num_fed_loss_classes minimum number of classes to keep when calculating federated loss. backbone produces [res2, res3, res4], any contiguous sublist One of: smooth_l1, giou, The default value of Point(-1, -1) denotes that the anchor is at the kernel center. The shackle pin should be securely wired or moused. and only predict other per-ROI outputs. Must be a subclass of Backbone. (in training only) match proposals with ground truth and sample them, crop the regions and extract per-region features using proposals, make per-region predictions with different heads. Abstract base class for network backbones. Implement RetinaNet in Focal Loss for Dense Object Detection. Note that only the shape of a cross-shaped element depends on the anchor position. ksize.width and ksize.height can differ but they both must be positive and odd.
