Find similar images

Reverse image search utility based on perceptual hash algorithms

The perceptual hashes are calculated from reduced 8x8 grayscale images:

Algorithm	Description
Average	Use the pixel's value and the average color
Block	Divide image in blocks and use their mean value
Difference	Use the difference between adjacent pixels
Perceptive	Use a discrete cosine transform (DCT) and compare frequencies rather than color values

Find similar images can be built from source with the 'SimilarImages.sln' Visual Studio 2013 solution.
