What's a "DHash"?
A DHash is a image perceptual hashing in which the image is reduced to 9x8 pixels and have it converted to grayscale. Each pixel is compared to the next: if it is whiter, the hash produces a 0 bit; if if is darker, it produces a 1. The final result is a 64-bit hash for the image.
Running
