Multiple Instance Curriculum Learning for Weakly Supervised Object Detection

no code implementations25 Nov 2017 Siyang Li, Xiangxin Zhu, Qin Huang, Hao Xu, C. -C. Jay Kuo

When supervising an object detector with weakly labeled data, most existing approaches are prone to trapping in the discriminative object parts, e. g., finding the face of a cat instead of the full body, due to lacking the supervision on the extent of full objects.
