## Overview

This is a small LMVD visual-feature conversion utility. When imported or run, `extract_npy_lmvd.py` walks `./lmvd/Video_feature`, processes CSV files not already converted, selects facial landmark coordinates, keeps every 30th frame, scales each row, and saves NumPy arrays under `./lmvd/visual`. The README is empty, so the workflow description is based on the sampled script; the input and output locations are hard-coded there.

Main entry points: [`extract_npy_lmvd.py`](https://github.com/blzs-zhjk/dynmultidep/blob/main/extract_npy_lmvd.py) (Batch traversal)

## Components

### Other components

- **Python runtime**
- [Batch traversal](https://github.com/blzs-zhjk/dynmultidep/blob/main/extract_npy_lmvd.py): `extract_npy_lmvd.py`
- [Landmark transform](https://github.com/blzs-zhjk/dynmultidep/blob/main/extract_npy_lmvd.py): `extract_npy_lmvd.py`
