Match faces in profile images via OpenCV.
As this package uses node-opencv you need to be aware that node-opencv requires OpenCV to be installed. Thus, before you npm install facematch you should install OpenCV.
On my Mac I installed OpenCV like this:
brew tap homebrew/science
brew install opencv
Then, in your project:
npm install facematch --save
Arguments: img1, img2, callback
The callback is called with the arguments err and diff.
img1 and img2 can be either Buffer or path.
var fm = new Facematch();
fm.compare(imgBuffer1, imgBuffer2, function (err, diff) {
if (err) throw err;
console.log('Images absDiff is %d', diff);
});
