## 📙 Overview

Egolearn video features.

1. egocentric videos are extracted by VideoMAE_L14 at 8 fps.
1. exocentric videos are extracted by InternVideo_MM_L14 at 8 fps.

They are used for evaluating the egovideo-exovideo retrieval ability of [EgoInstructor](https://arxiv.org/pdf/2401.00789).

Each file (e.g. 2cad4224-56c4-11ee-88ee-80615f12b59e.pth.tar) is a TxD feature vector, where T refers to the length of the video and D is 768.

## 🏋️ How-To-Use

Please refer to code [EgoInstructor](https://github.com/Jazzcharles/Egoinstructor/) for details.
