在HDevelop中
read_image (Image, 'D:/bb/tu/11.png') get_image_size (Image, Width, Height) dev_open_window (10, 10, Width, Height, 'black', WindowHandle) local_threshold (Image, Region, 'adapted_std_deviation', 'dark', [], []) *區域性閾值--適合不均勻照明-->漸變背景 *引數1:輸入影象 *引數2:分割後的區域 *引數3:分割方法 'adapted_std_deviation' *引數4:提取前景還是背景 dev_display(Region)
在QtCreator中
