Bounding Box Aware Text Extraction With Spatial Layout Preservation

via “bounding box extraction and spatial coordinate tracking”

Document preprocessing for RAG — parse PDFs, DOCX, images into clean structured elements.

Unique: Preserves and normalizes bounding box coordinates for every extracted element, enabling spatial awareness and document reconstruction. Includes utility functions for coordinate transformation and spatial analysis.

vs others: More comprehensive spatial tracking than text-only extractors (pypdf, pdfplumber); enables layout-aware downstream processing. Less specialized than dedicated layout analysis tools (Detectron2) but integrated into the extraction pipeline.
