$ npm install puzzle
then...
var puzzle = require('puzzle');
var context = puzzle.context(); // create a context
var distance = context.compare('./test/img/1.jpg', './test/img/2.jpg'); // compare two images
distance will be 0 if the images are equal, the larger the number, the more "different" the images are.
Generally, a number below .6 means they are considered similar. See the official libpuzzle docs for details.
node-gyp clean configure build && node test/test.js
This is very raw. It exposes exactly one method, there is a lot more to do. Contributions welcome.
