Paper Project Page

Given an egocentric video, Egoinstructor automatically retrieves semantically relevant instructional videos (e.g. from HowTo100M) via a pretrained cross-view retrieval model and leverages the visual/textual information to generate the caption of the egocentric video.

Roadmap

  • Retrieval code and data released
  • Captioning code and data released
  • Online Demo
  • Pre-trained retrieval checkpoints
  • Pre-trained captioning checkpoints

Prepare environment

Please refer to env.md

Cross-view Retrieval Module

To train a ego-exo crossview retrieval module, please refer to retrieval.

Retrieval-augmented Captioning

To train a retrieval-augmented egocentric video captioning model, please refer to captioning.
