As I know, "bbox" contains left top coordinate and right bottom coordinate.
To simple check data is fine, I printed max value of "bbox" and "segmentation".
As I understand, max value of "segmentation" and max value "bbox" have to be same.
(whatever that max value things means right bottom x or y)
but, max of "bbox" is 765 that right bottom y coordinate
and max of "segmentation" is 787.5 that point is on shoe bottom in my image.
Dictionary below is first images annotations information that made by pycococreator. This link is an image what I use for explain my question.

Is this my mistake? How can I fix this?
