Oriented reppoints
Witryna10 kwi 2024 · progressive regression： 作者发现旋转框在密集场景下的能有较好的目标检测精度，而水平框能达到更好的召回率，因此使用了这两种形式的框进行组合，具体做法是第一阶段检测水平框，从而提升检测速度，提高召回率，第二阶段也就是精炼阶段（refinement stage）检测旋转框，以适应密集目标的检测。 feature refinement … Witryna1.首先对预测的9个offset采用 1.4 reppoints转换为bbox 小节解码为bbox格式 bbox_pred_init = self.points2bbox( pts_pred_init.reshape(-1, 2 * self.num_points), y_first=False) 2.对预测框和gt bbox都除 …

WitrynaRepPoints是一种针对目标检测的表示方法，只采用9个点来表示目标， 这些点只包含了位置信息，无法表示物体更精细的结构，难以应用于实例分割任务。相比于RepPoints, Dense RepPoints使用更多的点表示物体，并增加了每个点的属性信息： 在刻画细粒度的物体几何定位时，有多重表示方式，见图4。 其中，基于轮廓的方法（图4 b）对物体 … Witryna17 kwi 2024 · Horizontal bounding boxes (HBB), oriented bounding boxes (OBB) and 4 point boxes (POLY) are supported in this toolbox. The program will confirm the type of bounding box by the tensor shape or the default setting.
