Analysis
This is a Show HN post presenting an OCR pipeline optimized for machine learning dataset preparation. The pipeline's key features include multi-stage OCR using various engines, handling complex academic materials (math, tables, diagrams, multilingual text), and outputting structured formats like JSON and Markdown. The project seems well-defined and targets a specific niche within the ML domain. The inclusion of sample outputs and real-world examples (EJU Biology, UTokyo Math) strengthens the presentation and demonstrates practical application. The GitHub link provides easy access to the code and further details.
