Abstract
A voting scheme for the design of composite filter is proposed here. Different types of synthetic discriminant function (SDF) filters, like minimum average correlation energy (MACE), minimum variance SDF (MVSDF), and optimal tradeoff SDF (OTSDF) have been proposed recently for the distortion-invariant recognition. Discretization of these filters is necessary to realize them using the available spatial light modulator (SLM), which limits the efficiency of the continuous domain filters. In this report, we address this SLM-constraint of the composite filter design. Our design starts with a binary SLM. In particular, binary modulation capability of the SLM is incorporated in the composite filter design as a constraint in the form of voting scheme nonlinearity.
