TL;DR: We present ViT-Lens, an approach for advancing omni-modal representation learning by leveraging a pretrained-ViT with modality Lens to comprehend diverse modalities.
- [2023.12.13] We release training code and models of ViT-Lens.
- [2023.11.28] We upgrade ViT-Lens, with added modalities and applications. Stay tuned for the release of code and models [
arXiv paper
]. - [2023.08.22] We release the arXiv paper, inference codes and checkpoints for 3D [
arXiv paper
].
- Models for more modalities.
- Code for ViT-Lens integration with InstructBLIP and SEED.
- Online demo for ViT-Lens integration with InstructBLIP and SEED.

We release a one-stop ViT-Lens-L
model (based on Large ViT) and show its performance on ModelNet40 (MN40, top1 accuracy), SUN RGBD Depth-only (SUN.D, top1 accuracy), NYUv2 Depth-only (NYU.D, top1 accuracy), Audioset (Audioset, mAP), VGGSound (VGGSound, top1 accuracy), ESC50 (ESC50, top1 accuracy), Clotho (Clotho, R@1/R@10), AudioCaps (AudioCaps, R@1/R@10), TAG.M (Touch-and-Go Material, top1 accuracy) and IN.EEG (ImageNet EEG, top1 accuracy). ViT-Lens consistently outperforms ImageBind.
For more model checkpoints (trained on different data or with better performance), please refer to MODEL_ZOO.md.
- You may set your paths for you own project in constants.py.
- We provide an API (source file) and provide an example (here) for reference. You can use ViT-Lens to extract and compare features across modalities:
