Hi HN,I’ve been working on an OCR pipeline specifically optimized for machine learning dataset preparation. It’s designed to process complex academic materials — including math formulas, tables, figures, and multilingual text — and output clean, structured formats like JSON and Markdown.Some features:
 • Multi-stage OCR combining DocLayout-YOLO, Google Vision, MathPix, and Gemini Pro Vision
 • Extracts and understands diagrams, tables, LaTeX-style math, and multilingual text (Japanese&#x2F;Korean&#x2F;English)
 • Highly tuned for ML training pipelines, including dataset generation and preprocessing for RAG or fine-tuning tasksSample outputs and real exam-based examples are included (EJU Biology, UTokyo Math, etc.)
Would love to hear any feedback or ideas for improvement.GitHub: <a href="https:&#x2F;&#x2F;github.com&#x2F;ses4255&#x2F;Versatile-OCR-Program">https:&#x2F;&#x2F;github.com&#x2F;ses4255&#x2F;Versatile-OCR-Program</a>

Written in Rust (embassy), running on a SparkFun ProMicro RP2040 board, with an MPU6050 gyroscope. Based on the Chordite idea from John W. McKown (<a href="https:&#x2F;&#x2F;web.archive.org&#x2F;web&#x2F;20220201061603&#x2F;http:&#x2F;&#x2F;chordite.com&#x2F;" rel="nofollow">https:&#x2F;&#x2F;web.archive.org&#x2F;web&#x2F;20220201061603&#x2F;http:&#x2F;&#x2F;chordite.c...</a>). Intended for use with XR glasses I recently bought. Currently my typing speed is still rather slow, but my skill is graduably improving and at a noticeable pace, and I can and do some vim coding in my hobby time. I plan to try and do a wireless (BLE) version next, hopefully running off a single AA NiMH battery.
