TAC RGB encoder

This model is used for encoding RGB image into a dense feature.

Caution, the model does not contain the last FC layer. So, the output features are not aligned with depth.

Model Details

Model Description

The model is pre-trained with RGB-D contrastive objectives, named TAC. Different from InfoNCE-based loss fuctions, TAC leverages the similarity between videos frames and estimate a similarity matrix as soft labels. The backbone of this version is ViT-B/32. The pre-training is conducted on a new unified RGB-D database, UniRGBD. The main purpose of this work is depth representation. So, the RGB encoder is just a side model.
