Component-based design for parallel moment generators

Moments are one of the most well known feature descriptors which can be extracted from an image; their mathematical properties and versatility as feature extractors are well studied. This paper presents a design of moment generators, using established techniques in digital filters and Very Large Scale Integration processing combined under a component-based design framework. Analytically, the moment generator architecture is constructed by cascading single- pole stages of a relatively simple filter suitable for implementation on an ASIC platform, and which is capable of producing a linear combination of moments. Individual set of moments can be extracted, by using dematrixing techniques which could also be realized in the form of a preprogrammable logic table. A parallel implementation of the design is described using C*, a data-parallel extension of ANSI C. Preliminary evaluation of the design and implementation is also presented.
