; shape (tuple[int]) – Expected padding shape (h, w).Default: None. Objects in a 3D world do not follow any particular orientation, and box-based detectors have difficulties enumerating all orientations or fitting an axis-aligned bounding box to rotated … padding (int or tuple[int]) – Padding on each border.If a single int is provided this is used to pad all borders. 物体检测和分割应该算是计算机视觉中常用的而且也比较酷的任务。但相比图像分类，物体检测和分割任务难度更大，另外一点是就是代码实现也更复杂。对于物体检测和分割，目前有以下几个通用的开源项 … [2] - 包含更多特性，如全景分割(panoptic segmentation)、densepose、Cascade R-CNN、旋转边界框(rotated bounding boxes) 等等. This representation mimics the well-studied image-based 2D bounding-box detection but comes with additional challenges.

Github - detectron2. Parameters: img (ndarray) – Image to be padded. Base bounding box coder. detectron2 主要特点： [1] - 基于 PyTorch 深度学习框架. class mmdet.core.bbox.PseudoBBoxCoder (**kwargs) [source] ¶ Pseudo bounding box coder. If tuple of length 2 is provided this is … encode (bboxes, gt_bboxes) [source] ¶ Encode deltas between bboxes and ground truth boxes. decode (bboxes, bboxes_pred) [source] ¶ Decode the predicted bboxes according to prediction and base boxes.
