Overview

PaddleOCR is a comprehensive OCR toolkit built on Baidu's PaddlePaddle deep learning framework. It provides state-of-the-art text detection and recognition with particularly strong performance on Asian languages.

The latest PP-StructureV3 adds table recognition, formula extraction, and handwriting support. PaddleOCR is optimized for both accuracy and inference speed, making it practical for real-time applications.

It offers multiple model sizes (from mobile-optimized to server-grade) and supports deployment across various platforms including ONNX Runtime.
