PyTorch implementation and pretrained models for ImageBind. For details, see the paper: ImageBind: One Embedding Space To Bind Them All.

ImageBind learns a joint embedding across six different modalities - images, text, audio, depth, thermal, and IMU data. It enables novel emergent applications ‘out-of-the-box’ including cross-modal retrieval, composing modalities with arithmetic, cross-modal detection and generation.

Usage

Install pytorch 2.0+ and other 3rd party dependencies.

conda create --name imagebind python=3.10 -y
conda activate imagebind
pip install .

For windows users, you might need to install soundfile for reading/writing audio files. (Thanks @congyue1977)

pip install soundfile

Extract and compare features across modalities (e.g. Image, Text and Audio).
