Image-Text Co-Decomposition

Code for CVPR 2024 Image-Text Co-Decomposition for Text-Supervised Semantic Segmentation

Paper

Notes on environment setup

1. It is best to start a new conda environment.

conda create -n [env_name] python=3.10
conda activate [env_name]

2. Install required packages

pip install torch==1.12.1 torchvision==0.13.1
pip install -U openmim
pip install -r requirements.txt
python -m mim install mmcv-full==1.6.2 mmsegmentation==0.27.0

3. Deal with NLTK stuffs

python
>>> import nltk
>>> nltk.download('punkt')
>>> nltk.download('averaged_perceptron_tagger')

Datasets

Note that much of this section is adapted from the data preparation section of TCL README.

Training datasets

In training, we use Conceptual Caption 3m and 12m. We use img2dataset tool and follow these instructions to download and preprocess the datasets.

Evaluation datasets

In the paper, we use 6 benchmarks; PASCAL VOC, PASCAL Context, and COCO-Object, COCO-Stuff, Cityscapes, and ADE20k. We need to prepare 5 datasets: PASCAL VOC, PASCAL Context, COCO-Stuff164k, Cityscapes, and ADE20k.

Please download and setup PASCAL VOC, PASCAL Context, COCO-Stuff164k, Cityscapes, and ADE20k datasets following MMSegmentation data preparation document.

COCO Object

COCO-Object dataset uses only object classes from COCO-Stuff164k dataset by collecting instance semgentation annotations. Run the following command to convert instance segmentation annotations to semantic segmentation annotations:

python convert_dataset/convert_coco.py data/coco_stuff164k/ -o data/coco_stuff164k/
