🎶 Introduction

X-Decoder is a generalized decoding model that can generate pixel-level segmentation and token-level texts seamlessly!

It achieves:

• State-of-the-art results on open-vocabulary segmentation and referring segmentation on eight datasets;
• Better or competitive finetuned performance to generalist and specialist models on segmentation and VL tasks;
• Friendly for efficient finetuning and flexible for novel task composition.

It supports:

• One suite of parameters pretrained for Semantic/Instance/Panoptic Segmentation, Referring Segmentation, Image Captioning, and Image-Text Retrieval;
• One model architecture finetuned for Semantic/Instance/Panoptic Segmentation, Referring Segmentation, Image Captioning, Image-Text Retrieval and Visual Question Answering (with an extra cls head);
• Zero-shot task composition for Region Retrieval, Referring Captioning, Image Editing.

Getting Started

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
sh install_cococapeval.sh
export DATASET=/pth/to/dataset

To prepare the dataset: DATASET.md

Open Vocabulary Segmentation

mpirun -n 8 python eval.py evaluate --conf_files configs/xdecoder/svlp_focalt_lang.yaml  --overrides WEIGHT /pth/to/ckpt

Note: Due to zero-padding, filling a single gpu with multiple images may decrease the performance.

Inference Demo

# For Segmentation Tasks
python demo/demo_semseg.py evaluate --conf_files configs/xdecoder/svlp_focalt_lang.yaml  --overrides WEIGHT /pth/to/xdecoder_focalt_best_openseg.pt
# For VL Tasks
python demo/demo_captioning.py evaluate --conf_files configs/xdecoder/svlp_focalt_lang.yaml  --overrides WEIGHT /pth/to/xdecoder_focalt_last_novg.pt
