# Amharic Image Text Comparison & Correction Tool This tool provides a full workflow for extracting Amharic text from images, comparing text layouts and content, rendering corrected text, and visualizing layout/text differences. It is ideal for OCR research, document verification, and Amharic text QA. ## Features - **OCR Extraction:** Accurate Amharic text and layout extraction from images using Tesseract. - **Text Reconstruction:** Rebuilds text with original line and word spacing. - **Comparison:** Detects and visualizes line-by-line and word-by-word differences (including spacing). - **Font Rendering:** Renders Amharic text to images with Abyssinica SIL font. - **Visual Diff:** Highlights spacing errors, word mismatches, and corrections directly on images. - **Modular Scripts:** Easy to run step-by-step or integrate as a pipeline. ## Directory Structure ``` amharic-image-diff/ ├── README.md ├── requirements.txt ├── ocr_extract.py ├── compare_texts.py ├── render_text.py ├── visualize_diff.py └── fonts/ └── AbyssinicaSIL-Regular.ttf ``` ## Setup 1. **Install Python dependencies** ```sh pip install -r requirements.txt ``` 2. **Install Tesseract and Amharic language pack** ```sh sudo apt-get update sudo apt-get install tesseract-ocr tesseract-ocr-amh ``` 3. **Download Abyssinica SIL font** ```sh mkdir -p fonts wget -O fonts/AbyssinicaSIL-Regular.ttf github.com ``` ## Usage ### 1.
