However, detection performance tends to degrade with increasing the IoU thresholds.

WebImage segmentation is the art of partitioning an image into multiple smaller segments or groups of pixels, such that each pixel in the digital image has a specific label assigned to it. Pixels with the same label have similarity in characteristics. After segmentation, the output is a region or a structure that collectively covers the entire image.
