PERFORMANCE COMPARISON OF TERNARY AND MINIMUM NOISE AND CORRELATION-ENERGY FILTERS USING REALISTIC TEST IMAGES

The correlation performance of minimum noise and correlation energy (M INACE) synthetic discriminant function (SDF) filters and distortion-in variant ternary phase-amplitude filters (TPAFs) on visible-wavelength images of an actual tank on a natural terrain background is compared i n simulations. The comparison is performed for four test images with t hree types of preprocessing: none, edge enhancement, and binarization. Testing is realistic in that it uses only scenes not included in the training images used to construct the filters. The implications of the results for correlator design are discussed.
