* Reduce size. The fastest way to remove high frequencies and detail is to shrink the image. In this case, shrink it to 9x8 so that there are 72 total pixels.
|

* Reduce color. Convert the image to a grayscale picture. This changes the hash from 72 pixels to a total of 72 colors.

* Assign bits. Each bit is simply set based on whether the left pixel is brighter than the right pixel.
