Error in annotation of CoCo? #4

Closed SohamTamba closed 4 years ago

SohamTamba commented 4 years ago

In th CoCo dataset, the annotations in this line bboxes[:, 2:] += bboxes[:, :2] # xywh to xyxy might be wrong. According to that line.

x_right = x_left + width
y_bottom = y_top + height

Shouldn't it be y_bottom = y_top - height?

This is because the axis origin of an image is at the top-left corner, just like a numpy array
