# TRUE-Colon: Real-Time Polyp Detection

Interactive demo of the **RT-DETR** detector from the paper *TRUE-Colon: Exposing a
Consistent Transfer Asymmetry in Real-Time Polyp Detection* (MICCAI 2026 EndoLINA
Workshop). The model was trained on **REAL-Colon** — 60 complete, unedited colonoscopy
procedures — and detects polyps (lesions) in individual colonoscopy frames.

## Usage

Upload a colonoscopy frame, adjust the confidence and IoU thresholds, and click
**Detect Polyps**. The model draws green bounding boxes around detected lesions with
confidence scores.

> ⚠️ **Research demo only — NOT for clinical use.** The model has not been validated
> prospectively or cleared by any regulator.

## Model

- **Checkpoint**: [`sdoerrich97/true_colon_rtdetr_realcolon_s0`](https://huggingface.co/sdoerrich97/true_colon_rtdetr_realcolon_s0)
- **Architecture**: RT-DETR (via Ultralytics)
- **Input**: 640 × 640
- **Classes**: 1 (`lesion`)
- **License**: AGPL-3.0 (inherited from Ultralytics training)
