Performance analysis of correlation filters used for face recognition

摘要

There are many approaches for designing filters to be used with optical correlation techniques that presents a good method to carry out instantly a decision on the target form. In this paper, we are interested on filters designs since their important role for target tracking and identification. Considering a Vanderlugt correlator (VLC), we discuss the basis of existing filters in the literature, and we carry out a performance analysis of the above filters in terms of Receiver Operating Characteristic (ROC) and peak-to-correlation energy (PCE). Simulation results prove that POF is more appropriate for optical correlator to be used for face recognition.
