| # ocr-data |
|
|
| Alshams, The largest Arabic OCR dataset at the word level. |
|
|
| This dataset is specifically designed for **fine-grained word-level OCR tasks**, providing **precise word-level bounding box annotations** for each image. |
|
|
| Each word is annotated with **pixel-accurate localization**, enabling tasks such as text detection, text recognition, and end-to-end OCR. |
|
|
| This repository currently provides an **Arabic OCR dataset**. |
|

| ## π Dataset Structure |
| |
| The dataset is organized into three main directories at the root level: |
| |
| ``` |
| ocr-data/ |
| βββ images/ |
| βββ labels/ |
| βββ texts/ |
| ``` |
| |

| |
| ### π· images/ |
| |
| - Contains OCR images in **PNG** format. |
| - Each image has a corresponding **JSON annotation file** with the same base filename. |
| - The JSON file precisely defines the location of each word in the image. |
| |
| ### π· labels/ |
| |
| - Contains **JSON annotation files** corresponding to the images. |
| - Each JSON file shares the same base filename as its related image. |
| - These files define **word-level annotations** with exact bounding box coordinates. |
| - The annotation structure is identical to the JSON format described in the `images/` section. |
| |
| JSON Annotation Format (per image) |
| |
| ```python |
| import json |
| with open(path_image_label, 'r', encoding='utf-8') as f: |
| data = json.load(f) |
| ``` |
| |
| ```json |
| { |
| "0": { |
| "word": "ΩΩΩ
Ψ©", |
| "location": { |
| "x": 3927, |
| "y": 481, |
| "w": 397, |
| "h": 170 |
| } |
| }, |
| "1": { |
| "word": "ΨΉΨ±Ψ¨ΩΨ©", |
| "location": { |
| "x": 3544, |
| "y": 481, |
| "w": 355, |
| "h": 170 |
| } |
| } |
| } |
| ``` |
| |
| - `word`: The recognized word in the image. |
| - `location`: Bounding box of the word: |
| - `x`, `y`: Top-left corner coordinates |
| - `w`, `h`: Width and height of the bounding box |
| |
| --- |
| |
| |
| ### π texts/ |
| |
| - Contains **TXT** files. |
| - Each text file corresponds to an image. |
| - Stores the **continuous (full) text** related to the image content. |
