SEGIC: Unleashing the Emergent Correspondence for In-Context Segmentation

Paper (ArXiv)

We introduce SEGIC, an end-to-end segment-in-context framework built upon a single frozen vision foundation model.

Model ZOO

Environment Setup

conda create --name segic python=3.10 -y
conda activate segic
pip install torch==1.13.1+cu117 torchvision==0.14.1+cu117 torchaudio==0.13.1 --extra-index-url https://download.pytorch.org/whl/cu117
pip install -r requirements.txt

Train SEGIC

bash scripts/segic_dist.sh 8 dinov2 OUTPUT/all_exps/abs_backbone/dinov2_l --dinov2_model l --samples_per_epoch 80000

Evaluate SEGIC
