1. Detection algorithm: DB, EAST, SAST
2. Recognition algorithm: Rosetta, CRNN, RARE, SRN, STAR-Net
3. PPOCR Chinese models： (1) Detection models: mobile, server (2) Text direction classification models: mobile (3) Recognition models: mobile, server
4. Multilingual models: (1) English: mobile (2) Japanese, Korean, French, German, etc. 25 languages in total: mobile

二、The related works on deployment have been well adapted, including Inference(Python, C++) , whl, and serving

三、Release the annotation and synthesis tools:

1. Release a new data synthesis tool, i.e., Style-Text，easy to synthesize a large number of images which are similar to the target scene image.
2. Release a new data annotation tool, i.e., PPOCRLabel, which is helpful to improve the labeling efficiency. Moreover, the labeling results can be used in training of the PP-OCR system directly.
