## What it is
An offline Chinese text detection and recognition OCR SDK with C++ core code and Python bindings, supporting models like CRNN, CTPN, and PixelLink, including curved and multi-line text. The project has declared itself largely complete and is transitioning into a research project exploring Transformer-based approaches, with maintenance paused.

## Use cases
- recognize chinese text in scanned documents offline
- extract text from images without internet
- detect and recognize curved text lines
- ocr sdk with python interface
- multi-line text recognition without bounding box annotation
- run ocr on gpu with cuda

## When to choose
- you need fully offline Chinese OCR on Linux
- you need to recognize curved or multi-line text that standard OCR fails on
- you want a C++ core with Python bindings and minimal dependencies

## When to avoid
- you need Windows or ARM support
- you need actively maintained software with a license
- you need production-grade OCR with guaranteed stability - the project is paused and carries a liability disclaimer

## Facets
- artifact type: library
- maturity: maintenance
- function: ocr, computer-vision, machine-learning, deep-learning
