Title
Body
I am developing a C++ application for face authentication. First, I have to detect the face and pre-process the image. For face detection I have used the HaarCascadeClassifier. The problem is that the this tool or this algorithm gives me a facial region detected by a little bit large rectangle that englobes hair and some of the background. Is there a solution to change the dimension of this rectangle? I used "frontalfacecascaadclassifier.xml". For face pre-processing i want to do face alignment exactly like this technique . How would I go about accomplishing this?
