This MR is the refactoring of the face cropping preprocessor. Two tasks are addressed:
First, the combination of two classes
ImageFaceCropsimplified to a single class namely
FaceCropAlign. This class can now be used with a
bob.bio.video.preprocessor. An example of how to use the class with Wrapper: https://gitlab.idiap.ch/bob/bob.pad.face/blob/preproc_refactor/bob/pad/face/config/lbp_svm.py
FaceCropAlign now also supports facial alignment, based on the positions of the eyes.
