小滑块为单独的png图片，背景是透明图，如下图

然后背景为带小滑块坑位的，如下图

  det = ddddocr.DdddOcr(det=False, ocr=False)
  
  with open('target.png', 'rb') as f:
      target_bytes = f.read()
  
  with open('background.png', 'rb') as f:
      background_bytes = f.read()
  
  res = det.slide_match(target_bytes, background_bytes)
  
  print(res)

提示：如果小图无过多背景部分，则可以添加simple_target参数，通常为jpg或者bmp格式的图片

    slide = ddddocr.DdddOcr(det=False, ocr=False)
    
    with open('target.jpg', 'rb') as f:
        target_bytes = f.read()
    
    with open('background.jpg', 'rb') as f:
        background_bytes = f.read()
    
    res = slide.slide_match(target_bytes, background_bytes, simple_target=True)
    
    print(res)

一张图为带坑位的原图，如下图

一张图为原图，如下图

  slide = ddddocr.DdddOcr(det=False, ocr=False)

  with open('bg.jpg', 'rb') as f:
      target_bytes = f.read()
  
  with open('fullpage.jpg', 'rb') as f:
      background_bytes = f.read()
  
  img = cv2.imread("bg.jpg")
  
  res = slide.slide_comparison(target_bytes, background_bytes)

  print(res)
