Abstract

Several methods of designing Synthetic Discriminant Function (SDF) filters exist. All of these require that the correlation output take on specified values at origin. In this paper, we examine the role of these correlation plane constraints. We show that the conventional practice (of forcing the correlation outputs to a constant for all training images from a single class) leads to poor discrimination. We introduce a new method to improve the discrimination capabilities of SDF filters.
