Bindings for node.js to pHash
node-pash is pHash bindings for node.js.
Phash is a library that will create a "perceptual hash" of media files, so similar files will return similar hashes. Typically to compare hashes, a simple Hamming distance between the two hashes is a good indicator of how similar two media files are.
Current version supports only image hashing. (no video & audio hashing)
sudo apt-get install cimg-dev libphash0-dev libmagickcore-dev
brew install phash imagemagick
Then, install using npm:
$ npm install phash
// asynchronous hash
var pHash = ;pHash;var hashA = pHash;var hashB = pHash;var hammingAB = pHash;console;
