I believe that you're using the node-opencv library ? You will need some more steps. You have to train your opencv system which than allows you to use the method "predictSync" from FaceRecongizer().

The node-opencv library has a FaceRecognizer Object which you first initialize.

Initialize FaceRecognizer: var FaceRecognizer = new cv.FaceRecognizer();
You have to read all the images, create a specific array and train your FaceRecognizer with that. For my purpose, I'm saving each user in a DB and they get a unique ID which I'm using to create a specific subfolder and this is later used. Here is my code:

Observables

You don't really need a framework or fancy cutting-edge JavaScript features to do two-way data binding. Let's start basic - first and foremost, you need a way to tell when data changes. Traditionally, this is done via an Observer pattern, but a full-blown implementation of that is a little clunky for nice, lightweight JavaScript. So, if native getters/setters are out, the only mechanism we have are accessors:

var n = 5;
function getN() { return n; }
function setN(newN) { n = newN; }

console.log(getN()); // 5

setN(10);
