It's a great code. It works well and the results are satisfactory, but the obj name file was not found. How should I organize it?

Hi, Thanks for the script. It works very well. But it cannot be used for the segmentation tasks since the script does not extract the segmentation from the COCO annotation.JSON. Can you help me with the above issue?

When bbox is tlbr, the result value is not accurate when using the existing calculation code. I may be wrong, but it looks like the calculation code needs to be corrected.
x = (bbox[0] + bbox[1]) / 2. y = (bbox[1] + bbox[3]) / 2. w = bbox[2] - bbox[0] h = bbox[3] - bbox[1] x = x / img_w y = y / img_h w = w / img_w h = h / img_h return x, y, w, h
