Paper Abstract

We describe a digital correlation mask that induces orthogonality among a prescribed set of reference imagery. In our particular implementation the resulting correlation is under sampled and shift variant, though if it is applied to optical correlators those limitations are removed. We derive a method of introducing orthogonality among the weights among the training set from which filter values are obtained, so that the correlation value from a given filter is representative of the unique nature of the reference object as compared against the other objects in the training class.
