rapidocr-openvino 1.2.12

A cross platform OCR Library based on OpenVINO.

rapidocr-openvino Package

1. Install package by pypi.

$ pip install rapidocr-openvino

2. Use.

• Run by script.

  import cv2
  from rapidocr_openvino import RapidOCR
  
  rapid_ocr = RapidOCR()
  
  img_path = 'tests/test_files/ch_en_num.jpg'
  
  # Support：Union[str, np.ndarray, bytes, Path]
  # str
  result, elapse = rapid_ocr(img_path)
  
  # np.ndarray
  img = cv2.imread('tests/test_files/ch_en_num.jpg')
  result, elapse = rapid_ocr(img)
  
  # bytes
  with open(img_path, 'rb') as f:
      result, elapse = rapid_ocr(f.read())
  
  # Path
  result, elapse = rapid_ocr(Path(img_path))
  print(result)
  
  # result: [[dt_boxes], txt, score]
  # e.g.：[[left-top, right-top, right-down, left-top], '小明', '0.99']
  
  # elapse: [det_elapse, cls_elapse, rec_elapse]
  # all_elapse = det_elapse + cls_elapse + rec_elapse
  
  # If without valid texts, result: (None, None )
  

• Run by command line.
