# Soccer Camera Detection Dataset

A curated dataset for classifying camera characteristics in broadcast soccer video, annotated with **9-class shot scale** (CineScale-aligned) and **5-class camera angle** (CineScale2-aligned).

### Shot Scale Examples

</p>
<p align="center">
  <em>Left:</em> <strong>MCU</strong> Medium Close-Up — head & shoulders &nbsp;|&nbsp;
  <em>Center:</em> <strong>LS</strong> Long Shot — full body &nbsp;|&nbsp;
  <em>Right:</em> <strong>ELS</strong> Extreme Long Shot — wide pitch view
</p>

### Camera Angle Examples

  <img src="previews/camera_angle_examples.jpg" width="100%" alt="Camera Angle: HIGH, NEU, LOW" />
</p>
<p align="center">
  <em>Left:</em> <strong>HIGH</strong> High Angle — elevated broadcast camera &nbsp;|&nbsp;
  <em>Center:</em> <strong>NEU</strong> Neutral — pitch-level eye height &nbsp;|&nbsp;
  <em>Right:</em> <strong>LOW</strong> Low Angle — camera below subject
</p>

## Dataset Description

This public sample consists of **650 frames** extracted from **10 video clips** of professional soccer broadcasts spanning 2013–2025. Each frame is annotated across two orthogonal dimensions:

- **Shot Scale** — how much of the subject is visible (9 classes from Extreme Close-Up to Extreme Long Shot)
- **Camera Angle** — the vertical orientation of the camera relative to the subject (5 classes from Overhead to Low Angle)

This is a representative sample of a larger dataset available for licensing. The full dataset covers hundreds of matches across multiple seasons and broadcast conditions — suitable for model training, fine-tuning, and research.

| MS | 85 | 13.1% |
| MCU | 50 | 7.7% |
| FS | 43 | 6.6% |
| IS | 14 | 2.2% |
| CU | 8 | 1.2% |
| ECU | 6 | 0.9% |

### Camera Angle Distribution

| Class | Frames | % |
|-------|--------|---|
| NEU | 369 | 56.8% |
| HIGH | 252 | 38.8% |
| LOW | 29 | 4.5% |
