Before revision: While common image object detection tasks focus on bounding boxes or segmentation masks as object representations, we  propose a novel method , named TetraPackNet, using fourcorner based object representations .
After revision: While common image object detection tasks focus on bounding boxes or segmentation masks as object representations, we consider the problem of finding objects based on four arbitrary vertices. We propose a novel method , named TetraPackNet, using fourcorner based object representations .
