Introduction

PaddleOCR aims to create multilingual, awesome, leading, and practical OCR tools that help users train better models and apply them into practice.

📣 Recent updates

  • 🔨2022.11 Add implementation of 4 cutting-edge algorithms:Text Detection DRRG, Text Recognition RFL, Image Super-Resolution Text Telescope,Handwrittem Mathematical Expression Recognition CAN

  • 2022.10 Release optimized JS version PP-OCRv3 model with 4.3M model size, 8x faster inference time, and a ready-to-use web demo

  • 💥 Live Playback: Introduction to PP-StructureV2 optimization strategy. Scan the QR code below using WeChat, follow the PaddlePaddle official account and fill out the questionnaire to join the WeChat group, get the live link and 20G OCR learning materials (including PDF2Word application, 10 models in vertical scenarios, etc.)

  • 🔥2022.8.24 Release PaddleOCR release/2.6

    • Release PP-StructureV2,with functions and performance fully upgraded, adapted to Chinese scenes, and new support for Layout Recovery and one line command to convert PDF to Word;
    • Layout Analysis optimization: model storage reduced by 95%, while speed increased by 11 times, and the average CPU time-cost is only 41ms;
    • Table Recognition optimization: 3 optimization strategies are designed, and the model accuracy is improved by 6% under comparable time consumption;
    • Key Information Extraction optimization:a visual-independent model structure is designed, the accuracy of semantic entity recognition is increased by 2.8%, and the accuracy of relation extraction is increased by 9.1%.
  • 🔥2022.8 Release OCR scene application collection

🌟 Features

PaddleOCR support a variety of cutting-edge algorithms related to OCR, and developed industrial featured models/solution PP-OCR and PP-Structure on this basis, and get through the whole process of data production, model training, compression, inference and deployment.

It is recommended to start with the “quick experience” in the document tutorial

🇺🇳 Guideline for New Language Requests

If you want to request a new language support, a PR with 1 following files are needed:

  1. In folder ppocr/utils/dict, it is necessary to submit the dict text to this path and name it with {language}_dict.txt that contains a list of all characters. Please see the format example from other files in that folder.

If your language has unique elements, please tell me in advance within any way, such as useful links, wikipedia and so on.

More details, please refer to Multilingual OCR Development Plan.
