Paper Abstract

We implement the continuous phase-only synthetic discriminant function using the commercial liquid crystal television. The filter is a nonlinear combination of the component phase-only filters of the training images and is generated with the iterative method. It produces narrow correlation peaks at the origin without sidelobe problem. Experimental results are shown.
