DiffSeg is an unsupervised zero-shot segmentation method using attention information from a stable-diffusion model. This repo implements the main DiffSeg algorithm and additionally include an experimental feature to add semantic labels to the masks based on a generated caption.

• The environment uses Ubuntu 18.04 and Tensorflow 2.14 supported on CUDA 11.x and python 3.9.

cd diffseg
conda create --name diffseg python=3.9
conda activate diffseg
pip install -r path/to/requirements.txt

• We recommend using 2 GPUs with a minimum 11G VRAM each, e.g., RTX2080Ti.
• One GPU is for loading the Stable Diffusion model and the other is for the BLIP captioning model.

Please see the instructions in the diffseg.ipynb for running instructions.

We benchmark the performance of DiffSeg on CoCo-Stuff-27 and Cityscapes. Please see instructions in benchmarks.ipynb.

• We follow the evaluation protocol in PiCIE and use the Hungarian algorithm for matching predictions and ground truth labels.
