Individual skill

video-tracker

Turns an experiment video into reproducible physics data: tracks declared objects (CSRT with template fallback), computes the amplitude spectrum of the coordinate series, and runs physics-consistency probes. Experimental and unstable — every run must be checked against a known reference.

# video-tracker

Extracts coordinates from a video, derives spectra, and probes physical
consistency. It never modifies the raw video and requires every parameter to
come from the config.

- **Stage:** `ingest` · **Sandbox:** no · **Dependencies:** `numpy`, `opencv` (`matplotlib` optional for figures)

## Quick Execution

Run this exact form — do not read the source tree:

```bash
python run.py --root <WS> --action probe -- --config cfg.json
