Definition
Tesseract is an open-source Optical Character Recognition (OCR) engine used in RAG pipelines to convert image-based data, such as scanned PDFs or screenshots, into machine-readable text for indexing. It utilizes an LSTM-based neural network to identify characters and lines, representing a privacy-centric, local-processing trade-off compared to higher-latency commercial cloud vision APIs.
Used for Optical Character Recognition (OCR) in document parsing, not 4D geometry or hypercubes.
"A digital transcriber reading a physical photocopy through a magnifying glass to type its contents into a searchable database."
- OCR(Core Technology)
- Data Ingestion(Pipeline Stage)
- Layout Analysis(Prerequisite for high accuracy)
