Abstract

We study the discrimination ability of a recently introduced optimum rotation invariant filter for disjoint noise. The discrimination ability of a sub-optimum filter related to the preceding one but where the non-target images are involved is also studied. The performance of both filters has been tested by computer simulations with a variety of natural and artificial backgrounds. The results obtained show an excellent performance much improved over the classical CHF (the filter that maximizes the SNR ratio while maintaining rotation invariance).
