If you are building a web application, a data processing pipeline, or a machine learning model, you might get a requirement to save images in Python while working with images. In this tutorial, I will explain several methods tosave images in Pythonusing different libraries with real examples. ...
我们可以使用os模块中的os.path.join()函数来将相对路径和当前工作目录拼接成完整的路径。 relative_path="images/example.jpg"save_path=os.path.join(os.getcwd(),relative_path) 1. 2. 上述代码中,os.getcwd()函数返回当前工作目录的路径,os.path.join()函数将当前工作目录和相对路径拼接起来,得到完整的保存...
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 cv2...
