'is crowd' parameter in FasterRcnn torchvision

Can someone explain about ‘is crowd’ parameter in FasterRcnn torchvision.what I understood is that those annotations with is_crowd=True is ignored during evaluation.Please someone explain it more.

AS far as I know, the iscrowd label is used in the cocoapi to determine the target type.
I.e. iscrowd = 0 uses polygons for the object instances, while iscrowd = 1 uses run-length encoding (RLE).
