👉 [New] demo code is available 👉 [New] OpenSeeD has been accepted to ICCV 2023! training code is available!

🚀 Key Features

• A Simple Framework for Open-Vocabulary Segmentation and Detection.
• Support interactive segmentation with box input to generate mask.

💡 Installation

pip3 install torch==1.13.1 torchvision==0.14.1 --extra-index-url https://download.pytorch.org/whl/cu113
python -m pip install 'git+https://github.com/MaureenZOU/detectron2-xyz.git'
pip install git+https://github.com/cocodataset/panopticapi.git
python -m pip install -r requirements.txt
export DATASET=/pth/to/dataset

Download the pretrained checkpoint from here.

💡 Demo script

python demo/demo_panoseg.py evaluate --conf_files configs/openseed/openseed_swint_lang.yaml  --image_path images/animals.png --overrides WEIGHT /path/to/ckpt/model_state_dict_swint_51.2ap.pt

🔥 Remember to modify the vocabulary thing_classes and stuff_classes in demo_panoseg.py if your want to segment open-vocabulary objects.

Evaluation on coco

python train_net.py --original_load --eval_only --num-gpus 8 --config-file configs/openseed/openseed_swint_lang.yaml MODEL.WEIGHTS=[/path/to/lang/weight](https://github.com/IDEA-Research/OpenSeeD/releases/download/openseed/model_state_dict_swint_51.2ap.pt)

You are expected to get 55.4 PQ.

💡 Some coco-format data

Here is the coco-format json file for evaluating BDD and SUN.
