| # Image Segmentation Using Text and Image Prompts | |
| This repository contains the code used in the paper ["Image Segmentation Using Text and Image Prompts"](https://arxiv.org/abs/2112.10003). | |
| **The Paper has been accepted to CVPR 2022!** | |

| The systems allows to create segmentation models without training based on: | |
| - An arbitrary text query | |
| - Or an image with a mask highlighting stuff or an object. | |
| ### Quick Start | |
| In the `Quickstart.ipynb` notebook we provide the code for using a pre-trained CLIPSeg model. If you run the notebook locally, make sure you downloaded the `rd64-uni.pth` weights, either manually or via git lfs extension. | |
| It can also be used interactively using [MyBinder](https://mybinder.org/v2/gh/timojl/clipseg/HEAD?labpath=Quickstart.ipynb) | |
| (please note that the VM does not use a GPU, thus inference takes a few seconds). | |
| ### Dependencies | |
| This code base depends on pytorch, torchvision and clip (`pip install git+https://github.com/openai/CLIP.git`). | |
| Additional dependencies are hidden for double blind review. | |
| ### Datasets | |
| * `PhraseCut` and `PhraseCutPlus`: Referring expression dataset | |
| * `PFEPascalWrapper`: Wrapper class for PFENet's Pascal-5i implementation | |
| * `PascalZeroShot`: Wrapper class for PascalZeroShot | |
| * `COCOWrapper`: Wrapper class for COCO. | |
| ### Models | |
| * `CLIPDensePredT`: CLIPSeg model with transformer-based decoder. | |
| * `ViTDensePredT`: CLIPSeg model with transformer-based decoder. | |
| ### Third Party Dependencies | |
| For some of the datasets third party dependencies are required. Run the following commands in the `third_party` folder. | |
| ```bash | |
| git clone https://github.com/cvlab-yonsei/JoEm | |
| git clone https://github.com/Jia-Research-Lab/PFENet.git | |
| git clone https://github.com/ChenyunWu/PhraseCutDataset.git | |
| git clone https://github.com/juhongm999/hsnet.git | |
| ``` | |
| ### Weights | |
| The MIT license does not apply to these weights. | |
| We provide two model weights, for D=64 (4.1MB) and D=16 (1.1MB). | |
| ``` | |
| wget https://owncloud.gwdg.de/index.php/s/ioHbRzFx6th32hn/download -O weights.zip | |
| unzip -d weights -j weights.zip | |
| ``` | |
| ### Training and Evaluation | |
| To train use the `training.py` script with experiment file and experiment id parameters. E.g. `python training.py phrasecut.yaml 0` will train the first phrasecut experiment which is defined by the `configuration` and first `individual_configurations` parameters. Model weights will be written in `logs/`. | |
| For evaluation use `score.py`. E.g. `python score.py phrasecut.yaml 0 0` will train the first phrasecut experiment of `test_configuration` and the first configuration in `individual_configurations`. | |
| ### Usage of PFENet Wrappers | |
| In order to use the dataset and model wrappers for PFENet, the PFENet repository needs to be cloned to the root folder. | |
| `git clone https://github.com/Jia-Research-Lab/PFENet.git ` | |
