bbox_overlaps计算方式 bbox_overlaps是一个计算两个矩形框之间重叠面积的函数。其计算方式为先计算两个矩形框在x和y轴上的重叠长度,然后将这两个长度相乘,得到重叠面积。具体计算公式为:overlap = max(0, min(xmax1, xmax2) - max(xmin1, xmin2)) * max(0, min(ymax1, ymax2) - max(ymin1, ...

I noticed that the code comment for BboxOverlaps2D states that If ``is_aligned`` is ``True``, then m and n must be equal., but the context does not give what n is. I think the n here should come from the shape of bboxes2 . I don't know i...

bbox_overlaps是一个用于计算两个边界框(boundingbox)重叠程度的函数,常用于目标检测领域。它的计算方式如下: 假设两个边界框分别为A和B,它们的坐标分别为(x1_A, y1_A, x2_A, y2_A)和(x1_B, y1_B, x2_B, y2_B)。其中,(x1, y1)表示左上角的坐标,(x2, y2)表示右下角的坐标。 首先,计算两...
