Show HN: OCR pipeline for ML training (tables, diagrams, math, multilingual)

OCR System Optimized for Machine Learning: Figures, Diagrams, Tables, Math & Multilingual Text Overview This OCR system is specifically designed to extract structured data from complex educational materials—such as exam papers—in a format optimized for machine learning (ML) training. It supports multilingual text, mathematical formulas, tables, diagrams, and charts, making it ideal for creating high-quality training datasets. Key Features – Optimized for ML Training: Extracted elements such as diagrams, tables, and figures are semantically annotated with contextual explanations. This includes automatic generation of natural language descriptions for visual content (e.g., “This figure shows the process of mitosis in four stages”) to enhance downstream model training. – Multilingual Support: Works with Japanese, Korean, and English, and can be easily customized for additional languages. – Structured Output: Generates AI-ready outputs in JSON or Markdown, including human-readable de ...
