Image analysis and comparison

Resemble.js

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

Get it

npm install resemblejs

bower install resemblejs

Example

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
	  dimensionDifference: { width: 0, height: -1 }, // defined if dimensions are not the same
	  getImageDataUrl: function(){}
	}
	*/
});

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

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

And change the output display style.

resemble.outputSettings({
  errorColor: {
    red: 255,
    green: 0,
    blue: 255
  },
  errorType: 'movement',
  transparency: 0.3
});
// resembleControl.repaint();
