PaddleOCR 2.9 - A new open-source optical character recognition (OCR) tool library released by Baidu PaddlePaddle.

What is PaddleOCR 2.9?

PaddleOCR 2.9 is an open-source optical character recognition (OCR) toolkit developed by Baidu PaddlePaddle. It offers a rich set of algorithms and models, supports multiple languages, and provides data annotation and synthesis tools. PaddleOCR 2.9 significantly enhances document scene information extraction capabilities, releasing the open-source version PP-ChatOCRv3-doc to improve the accuracy of page layout parsing and information extraction. PaddleOCR 2.9 adds several practical basic OCR models, such as page layout region detection and table recognition. PaddleOCR 2.9 supports low-code, end-to-end development, simplifies the Python API, making model calling, combination, and customization more efficient, supports multiple hardware platforms, reduces development difficulty, and accelerates the application of OCR technology across various industries.

Main functions of PaddleOCR 2.9

• Document Scene Information ExtractionBased on the open-source version of PP-ChatOCRv3-doc, it performs high-precision text image layout parsing and extracts structured information from documents.
• Multi-model integrationIt integrates 17 OCR-related models, including layout area detection, table recognition, and formula recognition, forming 6 model production lines, which can be called with one click using Python API.
• Low-code end-to-end developmentIt supports the use, combination, and customization of models using unified commands or a graphical interface, reducing the development threshold and improving development efficiency.
• High-performance inference and deploymentIt supports multiple deployment methods, including high-performance inference, service-oriented deployment, and edge deployment, to adapt to different application scenarios.
• Hardware platform supportIt is compatible with a variety of mainstream hardware platforms, such as NVIDIA GPUs, Kunlun chips, Ascend, Cambricon, etc., enabling seamless switching.
