Visual modality

This folder tackles the visual modality. It extracts features and provides some baselines.

Feature extraction

Download the videos from Google Drive to data/videos, placing the files there without subdirectories.
Move to this directory:
```
cd visual
```
Run save_frames.sh to extract the frames in the video files:
```
./save_frames.sh
```
To extract the features and save them in heavy H5 files:
```
./extract_features.py resnet
```
