What is cv2 resize ()?

OpenCV provides the function cv2. resize() to resize an image. Resizing in OpenCV is referred to as scaling. We can resize an image by specifying the image size or scaling factor. The aspect ratio is preserved when we specify the scaling factor.

How do I resize an image in bulk in Python?

You can resize multiple images in Python with the awesome PIL library and a small help of the os (operating system) library. By using os. listdir() function you can read all the file names in a directory. After that, all you have to do is to create a for loop to open, resize and save each image in the directory.
