Define a 2-class classifier its method and procedures Supervised training Show many positive samples(face) to the system Show many negative samples(non- face) to the system Learn the parameters and construct the final strong classifier. Detection Given an unknown input image the system can tell if there are faces or not Adaboost, VgaDefine a 2-class classifier :its method and procedures • Supervised training – Show many positive samples (face) to the system – Show many negative samples (non-face) to the system. – Learn the parameters and construct the final strong classifier. • Detection – Given an unknown input image, the system can tell if there are faces or not.
