Converts scanned or digital images of scientific papers, technical documents, and academic PDFs into structured Markdown text using a vision-encoder-decoder architecture. The model employs a Swin Transformer vision encoder to extract spatial features from document images, then decodes them into LaTeX-compatible Markdown using a transformer decoder trained on arXiv papers. This enables preservation of mathematical equations, tables, and hierarchical document structure in machine-readable format.
Unique: Trained specifically on arXiv papers using a vision-encoder-decoder architecture that preserves mathematical equations and scientific notation in Markdown/LaTeX format, rather than generic OCR that treats equations as image regions. Uses Swin Transformer for hierarchical visual feature extraction optimized for document structure.
vs alternatives: Superior to traditional OCR (Tesseract, EasyOCR) for scientific documents because it understands equation context and outputs LaTeX-compatible Markdown; more specialized than general vision-language models (CLIP, LLaVA) which lack equation-aware training data.
