Some notes to the repository
This repository has been created because the official pHash project (phash.org) does not have a public code RCS. The intension being that this repo is used for public co-operation which will be fed back to the main project. Obviously, any further releases from the official source will be pulled in here also.
The repository started with the downloadable version 0.9.4. The following information has been taken from the official website phash.org

What is pHash?
pHash is an open source software library released under the GPLv3 license that implements several perceptual hashing algorithms, and provides a C-like API to use those functions in your own programs. pHash itself is written in C++.
