Weakly-supervised semantic segmentation aims to train a network using weak labels. Among labels, image-level label has been the most popular choice due its simplicity. However, since labels lack accurate object region information, additional modules such as saliency detector have exploited in weakly supervised segmentation, which requires pixel-level for training. In this paper, we explore self...
