Automatic target recognition system with elliptical laplacian pyramid filter

摘要

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.
