# 将下面的这句替换掉 cv2.imwrite(save_path, img) # 可以替换成 cv2.imencode('.jpg', img)[1].tofile(file_path) # 英文或中文路径均适用 Q&A Q:为什么 OpenCV 不支持中文路径? A:OpenCV 库是在 C++ 写的,而在较早版本的 C++ 标准中并未提供直接的 Unicode 或者多字节字符编码支持。所以,OpenCV...

While working with images in Image Processing applications, quite often, you may need to store intermediate results of image transformations or save the final resulting image. When working with OpenCV Python, images are stored in NumPy ndarray. To save an image to the local file system, use cv...
