The CAM in weakly supervised semantic segmentation suffers from over-activation from co-occurred background regions. Luckily, We observe that co-occurred background sometimes present in image solely and its cues can be easily captured through image-level labels. In detail, the framework is as follows, which insists of Online Prototype Computing and Training with Prototype parts.

git clone https://github.com/mt-cly/FPR.git
conda create -n fpr python=3.8
conda activate fpr
cd ./FPR
pip install -r requirements.txt

1. Download the augmented VOC12 & COCO14 and put them to the Dataset folder.
2. Download the CAM initial weight and place it to the sess folder.

python run_sample.py

The trained fpr weight and log are available: [res50_fpr.pth] [fpr.log]

• Release the COCO2014 part code.
