pdf-document-layout-analysis provides a Docker-powered microservice for advanced PDF document layout analysis. This service enables OCR, segmentation, and classification of various PDF elements like text, titles, images, and tables. The core objective is to provide a robust and flexible solution for understanding the structure and content of PDF documents, improving data extraction and processing workflows. The primary technology used is Python with FastAPI for building a RESTful API and leveraging pre-trained models for layout analysis and OCR.
This project distinguishes itself through its Clean Architecture, promoting modularity, testability, and maintainability. It offers both a user-friendly Gradio web interface and a comprehensive REST API for versatile integration options. The ability to choose between VGT (Vision Grid Transformer) for high accuracy and LightGBM for speed provides flexibility in balancing performance and precision. Automatic translation using Ollama models further expands the service's utility.
