Hello, I am asking about the createLBPHFaceRecognizer() function, how does it really works? in its parameter there are a number representing sampling point and a radius. As far as I know, the input face image should be divided into regions . Then a histogram should be calculated from each region, and then all these histograms are combined forming one global histogram representing the input face image. This global histogram called spatially enhanced histogram. My question is that did this function do all of that? or it just treat the face image as one region and find one histogram representing the image. Thanks

And if it does, then how many regions are there? and can i change the number of regions? Thanks
