High-Precision Dichotomous Image Segmentation via Probing Diffusion Capacity

     

This repository contains the official implementation for the paper "High-Precision Dichotomous Image Segmentation via Probing Diffusion Capacity" (ICLR 2025).

How to use

For the complete training and inference process, please refer to our GitHub Repository. This section specifically guides you on loading weights from Hugging Face.

Install Packages:

pip install torch==2.2.0 torchvision==0.17.0 torchaudio==2.2.0 --index-url https://download.pytorch.org/whl/cu118
pip install -r requirements.txt
pip install -e diffusers-0.30.2/
