Environment

conda create -n diffcut python=3.10
conda activate diffcut
pip install -r requirements.txt

For evaluation, install detectron2

python -m pip install 'git+https://github.com/facebookresearch/detectron2.git'

Demo

Try DiffCut by running the notebook diffcut.ipynb

Visualize the semantic coherence of vision encoders with semantic_coherence.ipynb

Evaluation

Datasets Preparation

In the paper, we evaluate DiffCut on 6 benchmarks: PASCAL VOC (20 classes + background), PASCAL Context (59 classes + background), COCO-Object (80 classes + background), COCO-Stuff (27 classes), Cityscapes (27 classes) and ADE20k (150 classes). See Preparing Datasets for DiffCut.

Run Evaluation

python eval_diffcut.py --dataset_name Cityscapes --tau 0.5 --alpha 10 --refinement
