# collidingScopes/tennis-cv

> A guide to building a tennis computer vision system: from footage of a ball hit against a practice wall it counts strokes, measures speed and type (forehand/backhand) and wall impact points, producing an annotated video and a stats dashboard.

## Useful for

- Build your own wall-stroke tracker by training a detector on your footage
- Label frames via Roboflow and train RF-DETR to detect ball and racket
- Set up Kalman-filter ball tracking and build a stroke stats dashboard

## Why it’s here

- The repository is 16 days old and already has 71 stars.

## Star trust

Star growth looks organic.

Star-trust labels are heuristics based on the repository’s behavior, not a check of every stargazer.

Magnitude (0–10) measures how fast and how unusually interest in a repository is growing right now. It is not a quality score.
Days are UTC. “So far today” is a fact; “expected by the end of the day” is a forecast.
Summaries and use cases are written by an LLM (DeepSeek V4.1 Flash) from the README and may be inaccurate: verify specific claims (benchmarks, speed, hardware) in the repository itself.
