You must have definitely used a text-based search or even implemented one. But do you know, you can now even perform an image-based search? Of course, Google does that quite nicely. How do you think it does that? If you have to implement one yourself, you better know how to compare two images. Based on your use case, you may also want to get a diff or the difference between two images. In this recipe, we will cover two use cases:

  • How to get the difference between two images and store the difference as an image

  • How to objectively compare two images with scientific methods

Getting ready

In this recipe, we will continue using Pillow to compare images. Along with our Image class, we will also use the ImageChops class to get the difference between two images. We will use the scipy module to compare the images at the pixel level.

  1. We already have the Pillow module installed, so let's go ahead and install the scipy module using Python pip. On Mac OS X machine, you'll...
