Optically-facial Identification System on the Optical JTC in Mobile Networks
We have so far designed and constructed a facial recognition system based on the optical parallel Joint Transform Correlator combined with a digital computer. In addition to this, we devices a compact prototype PJTC (COPaC) and examined it for a practical use. According to the guideline for identification using biometrics, we carried out the accuracy evaluation by one-to one collation using 300 facial images. We ascertained its performance to be remarkably precise and thus reliable. In this paper, we proposed the Real-time individual authentication system in the mobile network, which is based on an optical correlation. It was examined for the influence of the camera resolution, image compression and background removal. Consequently, we confirmed that this system is highly robust against these potential influences. Moreover, we tested this in a wireless LAN environment, and verified its high possibility for a further facial identification use.
