MS COCO classifies objects as small, medium and large on the basis of their area. About 41% of objects are small, 34% are medium and 24% are large.

I want to know how does this '41%, 34% and 24%' division percentages came from? Is their any statistical reasoning for that?

https://github.com/cocodataset/cocoapi/issues/325 Anyone knows how to change cocoapi to set threshold for small/medium/large AP evaluation?

https://cocodataset.org/#detection-eval from the metrics section, I think it's just classifying the targets' area by [32^2, 96^2]
