Abstract:

It is difficult and expensive to obtain labels for image semantic segmentation tasks. This has led to more and more researches focusing on weakly supervised semantic segmentation (WSSS) with image-level labels and the class activation maps (CAM) is often used to locate objects. The performance of WSSS methods largely depends on the accuracy of the generated CAMs, but current methods can only perform rough locali/ation, especially cannot fit CAM to the object’s edge well. Therefore, we propose the Edge Enhancement Network (EEN), which uses the shallow features of the network to enhance edge information. This allows us to obtain more accurate CAMs that fit the edges only through image-level labels. It greatly improves the accuracy of pseudo ground truth and easily reaches the level of current mainstream methods. After many experiments, it has reached 67.0% mIoU on the Pascal VOC2012 validation set, which exceeds the latest method under the same training settings.
