I am trying to understand the box proposals that are generated by the RPN, particularly in the anchor_head_single.py file. I have printed several box predictions and they are quite strange to me. The center coordinates are many times negative but this could make some sense. But the width, height and length also come with negative values!? Could you please help me understand how these proposals could have negative values?
