(Again not mandatory but for our convenience, we will save the output image with the name of “output.png” with the help of the Image.save() method. Although image subscripting is supported, individually accessing each pixel of a large image isnt recommended to do from Python, as it will significantly. Finally, after updating or changing the pixel value we will get the output image.Then with the help of loops, we will iterate and change our desired value of the pixel. The Image.size method returns the width and height(column and row) of the image(pixelmap or matrix). Secondly, we need to extract the pixel map of the input image(the matrix of pixel values) with the help of the Image.load() method so that we can manipulate our desired pixel.(Not mandatory but for our convenience, we have saved the image with the name of “input.png” especially to look at the difference.) Both the cases have been shown in the below example. This image file can either be created through the Image.new() method or be imported from the local machine through the Image.open() method. First, we need an image file as input.

We can execute our script by issuing the following command: python compare. Finally, we can compare our images together using the compareimages function on Lines 68-70. Our plot is then displayed to us on Line 65. You can find the nearest neighbors for every pixel in an image with something like. On Lines 52-65 we simply generate a matplotlib figure, loop over our images one-by-one, and add them to our plot. The pixellated squares will be a visible jump in RGB values around a region.
