Image analysis and comparison

node-resemble

Request for maintainer: https://github.com/kpdecker/node-resemble/issues/11

Node port of Resemble.js.

Analyse and compare images with Javascript and HTML5. Resemble.js Demo

Retrieve basic analysis on image.

var api = resemble(fileData).onComplete(function(data){
console.log(data);
/*
{
  red: 255,
  green: 255,
  blue: 255,
  brightness: 255
}
*/
});

Use resemble to compare two images.

var diff = resemble(file).compareTo(file2).ignoreColors().onComplete(function(data){
console.log(data);
/*
{
  misMatchPercentage : 100, // %
  isSameDimensions: true, // or false
  getImageDataUrl: function(){} // returns base64-encoded image
  pngStream: function(){} // returns stream with image data
  getBuffer: function(cb){} // calls callback with image buffer
}
*/
});

You can also change the comparison method after the first analysis.

// diff.ignoreNothing(); 
// diff.ignoreColors(); 
diff.ignoreAntialiasing();
