Fast and efficient way to detect if two images are visually identical in Python
Question: Given two images:

    
    
    image1.jpg
    image2.jpg
    

What's a fast way to detect if they are visually identical in Python? For
example, they may have different EXIF data which would yield different
checksums, even though the image data is the same).

Imagemagick has an excellent tool, "identify," that produces a visual hash of
an image, but it's very processor intensive.


Answer: Using PIL/Pillow:

    
    
    from PIL import Image
    
    im1 = Image.open('image1.jpg')
    im2 = Image.open('image2.jpg')
    
    if list(im1.getdata()) == list(im2.getdata()):
        print "Identical"
    else:
        print "Different"
