GitHub - PaddlePaddle/PaddleOCR at release/2.5

English | 简体中文

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

• 🔥2022.7 Release OCR scene application collection
  • PaddleOCR scene application covers general, manufacturing, finance, transportation industry of the main OCR vertical applications, including digital tube, LCD screen character, license plate, high-precision SVTR model, etc. 7 vertical models.
• 🔥2022.5.9 Release PaddleOCR release/2.5
  • Release PP-OCRv3: With comparable speed, the effect of Chinese scene is further improved by 5% compared with PP-OCRv2, the effect of English scene is improved by 11%, and the average recognition accuracy of 80 language multilingual models is improved by more than 5%.
  • Release PPOCRLabelv2: Add the annotation function for table recognition task, key information extraction task and irregular text image.
  • Release interactive e-book "Dive into OCR", covers the cutting-edge theory and code practice of OCR full stack technology.
• 2021.12.21 Release PaddleOCR release/2.4
  • Release 1 text detection algorithm (PSENet), 3 text recognition algorithms (NRTR、SEED、SAR).
  • Release 1 key information extraction algorithm SDMGR and 3 DocVQA algorithms (LayoutLM, LayoutLMv2, LayoutXLM).
• 2021.9.7 Release PaddleOCR release/2.3
  • Release PP-OCRv2. The inference speed of PP-OCRv2 is 220% higher than that of PP-OCR server in CPU device. The F-score of PP-OCRv2 is 7% higher than that of PP-OCR mobile.
• 2021.8.3 Release PaddleOCR release/2.2
  • Release a new structured documents analysis toolkit, i.e., PP-Structure, support layout analysis and table recognition (One-key to export chart images to Excel files).
• more

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 start” in the document tutorial

• One line of code quick use: Quick Start
• Web online experience for the ultra-lightweight OCR: Online Experience
• Mobile DEMO experience (based on EasyEdge and Paddle-Lite, supports iOS and Android systems): Sign in to the website to obtain the QR code for installing the App

• Dive Into OCR 📚

• For international developers, we regard PaddleOCR Discussions as our international community platform. All ideas and questions can be discussed here in English.

• For Chinese develops, Scan the QR code below with your Wechat, you can join the official technical discussion group. For richer community content, please refer to 中文README, looking forward to your participation.

• For more model downloads (including multiple languages), please refer to PP-OCR series model downloads.
• For a new language request, please refer to Guideline for new language_requests.
• For structural document analysis models, please refer to PP-Structure models.

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.
