Description

Hey. I do not have static photos, I want to train the model dynamically. So I need a method update. In the original opencv_contrib, this method is present: https://github.com/kyamagu/mexopencv/blob/master/opencv_contrib/%2Bcv/LBPHFaceRecognizer.m#L306

const lbph = new cv.LBPHFaceRecognizer()
lbph.update([resizeFaceImage], [0])

TypeError: lbph.update is not a function

Contributor guide

Research direction
Implement the missing `update` method by creating a C++ binding to cv::face::LBPHFaceRecognizer::update from opencv contrib, then exposing it via Node API.
