This model is a fine-tuned version of unsloth/Qwen2-VL-2B-Instruct on an Arabic OCR dataset. It is optimized to perform Arabic Optical Character Recognition (OCR) for full-page text.
The model has been evaluated on standard OCR metrics, including Word Error Rate (WER), Character Error Rate (CER), and BLEU score.
| Model | WER β | CER β | BLEU β |
|---|---|---|---|
| Qari v0.1 Model | 0.068 | 0.019 | 0.860 |
| Qwen2 VL 2B | 1.344 | 1.191 | 0.201 |
| EasyOCR | 0.908 | 0.617 | 0.152 |
| Tesseract OCR | 0.428 | 0.226 | 0.410 |
The Fine-Tuned Model outperforms other solutions with:
While the Arabic OCR model demonstrates strong performance under specific conditions, it has several limitations:
Font Dependency: The model was trained using a limited set of fonts (Almarai-Regular, Amiri-Regular, Cairo-Regular, Tajawal-Regular, and NotoNaskhArabic-Regular). As a result, its accuracy may degrade when processing text in other fonts, particularly decorative or stylized typefaces.
Font Size Restriction: Training was conducted with a fixed font size of 16. Variations in font size, especially very small or large text, may reduce recognition accuracy.
Diacritics Exclusion: The model does not support Arabic diacritics (Tashkeel). Text that relies on diacritics for disambiguation may not be correctly recognized.
Lack of Handwriting Support: The model is not trained to recognize handwritten text, limiting its applicability to printed documents only.
Full-Page Processing: The model was trained on full-page text recognition, which may impact its performance on segmented text, cropped sections, or text within complex layouts such as tables and multi-column formats.
These limitations should be considered when deploying the model in real-world applications to ensure optimal performance.
