Paper Abstract

Experiments on an optical pattern recognition system used for validation and security verification are provided. The system verifies a random phase mask bonded to a gray scale primary image. Using a limited set of images, the system performance is investigated in the presence of different types of input noise and distortions such as scratches, fingerprints, and bendings. The experimental results indicate that for the noise and the distortion tested here, the system provides a good correlation performance by verifying the phase mask.
