How facemarkLBF work?

edit

@phillity In facemarkLBF cascade classifier is used to detect face. When res10_300x300_ssd_iter_140000 is used to detect face Facemark are not at same location. I don't think that's a problem. Are you agree with me?

@LBerger Ya, unless the facial landmark points seem wrong or are really different, I would think it's okay

The facial bounding boxes returned by the cascade classifier and the ssd will likely be different, so I would guess the facial landmarks extracted from each would also be different. Hopefully they would be close though

in green cascade classifier and in yellow res10_300x300_ssd_iter_140000 facemark are differents but the logic is good :

Ya I think the logic is correct. Since the facial bounding boxes are different, facial landmarks are found using different regions of the image
