引言 在人脸检测算法如R-CNN、Fast RCNN中都用到了bounding box回归,回归的目标是使得预测的物体窗口向groundtruth窗口相接近。我一开始没理解如何能回归出一个框来,看完下文就理解了 1. 为什么要做Bounding-box regression? 图10 示例 如图10所示,绿色的框为飞机的Ground Truth,红色的框是提取的Regio... ...

This error happens when you have an empty mask (all zeros). The bounding box is calculated from the mask (the smallest box that encapsulates all the pixels in the mask). So if the mask is all zeros, the bounding box dimensions will be zero as well, and that causes this error. I jus...
