Very interesting approach.

I have worked with image feature extraction in the past. Although using DCT coefficients has been used as a way to analyze texture features, the idea idea of generating the hash (step 5) seems to be new.

I am curious however on why you are discarding color information. Usually for reverse image search this kind of information can be quite useful.

Not new. pHash (phash.org) has been doing it for a while now. :)
