• Python 2.7
• Tensorflow 1.2 or higher
• PyDenseCRF

Partial coda and data preparation are borrowed from TF-phrasecut-public. Please follow their instructions to make your setup ready. DeepLab backbone network is based on tensorflow-deeplab-resnet as well as the pretrained model for initializing weights of our model.

python main_cmsa.py -m train -w deeplab -d Gref -t train -g 0 -i 800000

python main_cmsa.py -m test -w deeplab -d Gref -t val -g 0 -i 800000

A trained model is available here. You should be able to produce results on Gref validation dataset as 39.96% / 40.07% (without/with CRF) in terms of IoU.
