• Abstract: Weakly supervised semantic segmentation (WSSS), which aims to mine the object regions by merely using class-level labels, is a challenging task in computer vision. The current state-of-the-art CNN-based methods usually adopt Class-Activation-Maps (CAMs) to highlight the potential areas of the object, however, they may suffer from the part-activated issues. To this end, we try an early attempt to explore the global feature attention mechanism of vision transformer in WSSS task. However, since the transformer lacks the inductive bias as in CNN models, it can not boost the performance directly and may yield the over-activated problems. To tackle these drawbacks, we propose a Convolutional Neural Networks Refined Transformer (CRT) to mine a globally complete and locally accurate class activation maps in this paper. To validate the effectiveness of our proposed method, extensive experiments are conducted on PASCAL VOC 2012 and CUB-200-2011 datasets. Experimental evaluations show that our proposed CRT achieves the new state-of-the-art performance on both the weakly supervised semantic segmentation task the weakly supervised object localization task, which outperform others by a large margin.

  Weakly supervised semantic segmentation (WSSS) is a fundamental computer vision task, which aims to segment out the object within only class-level labels. Traditional methods adopt the CNN-based network and utilize the class activation map (CAM) strategy to discover the object regions. An alternative is to explore vision transformers (ViT) to encode the image to acquire the global semantic information. We propose a dual network with both CNN-based and transformer networks for mutually complementary learning.

  Weakly supervised object localization (WSOL) strives to learn to localize objects with only image-level supervision.

We propose a novel Semantic-Constraint Matching Network (SCMN) via a transformer to converge on the divergent activation.
