+# SceneText50
+
+SceneText50 is a diverse multilingual outdoor dataset introduced in the paper [Back-Tracking from Clarity: Self-Learning to See Text from Afar](https://huggingface.co/papers/2609.32477).
+
+It consists of 50 outdoor ego-centric videos (~840 clips) from 17 countries, with quadrilateral text annotations. The annotations are for **evaluation**; the self-learning pipeline introduced in the paper needs no manual labels for training.
+
+Code: https://github.com/trid2912/BackTrackingText
+
+## Dataset structure
+
+```text
+tracking_data/
+├── 01/ 02/ ... 50/                 # one folder per video
+│   ├── clip_10/                    # a clip = a short frame sequence
+│   │   ├── clip_10_0000.jpg
+│   │   ├── clip_10_0001.jpg
+│   │   └── ...
+│   ├── clip_10_0000.txt            # per-frame annotation (same basename as the frame)
+│   ├── clip_10_0001.txt
+│   └── ...
+```
+
+Each annotation line is one text instance:
+
+```text
+instance_id x1 y1 x2 y2 x3 y3 x4 y4
+```
+
+`instance_id` is the track ID (consistent across frames of a clip) and the four `(x, y)` pairs are the clockwise quadrilateral corners.
+
+## Sample usage
