Automatic target recognition system and/or method which employs an
elliptical Laplacian pyramid based pre-screen image data filter. The
filter is a resolution sequence matched filter, where the elliptical
Laplacian operator reflects the size, spatial characteristics and image
intensity level of prospective, candidate targets embedded in the image
data. Targets which exhibit a rectangular or elliptical shape at various
aspect angles are more therefore more effectively and efficiently
identified and located.
