Face Recognition Under Angular Constraint Using Discrete Wavelet Transform And Principal Component Analysis With Singular Value Decomposition

ABSTRACT The complexity of a face’s components originates from the incessant variations in the facial component that occur with respect to time. Notwithstanding of these variations, humans recognise a person very easily using physical characteristics such as faces, voice, gait, etc. In human interactions, the articulation and perception of constraints; like head-poses, facial expression form a communication channel that is additional to voice and that carries crucial information about mental, emotional and even physical states of a conversation. Automatic face recognition deals with extractin…
