CV_LOAD_IMAGE_ANYDEPTH - If set, return 16-bit/32-bit image when the input has the corresponding depth, otherwise convert it to 8-bit. CV_LOAD_IMAGE_COLOR - If set, always convert image to the color one CV_LOAD_IMAGE_GRAYSCALE - If set, always convert image to the grayscale one >...

这会生成一个名为image_processing.so(或image_processing.pyd)的共享库文件,可以在Python中导入并使用。 下面是一个使用示例: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 pythonCopy codeimport cv2 from image_processingimportconvert_to_grayscale ...
上面主要是命令行参数解析的相关程序,有两个参数: - --image:要传入OCR系统的图片路径 - --preprocess:预处理方法,可以接受两个值,thresh 或者 blur。 接下来,我们将加载图像,将其二值化,并写入磁盘。 # load the example image and convert it to grayscale ...
