Abstract : The patent describes a technique and apparatus for two dimensional pattern analysis utilizing a transform of the pattern which enables the extraction of desired pattern information by means of spatial filtering in accordance with known human visual system processing. Two dimensional spatial frequencies resulting from the transform are acted on by either anisotropic or uniquely used conventional filters to extract one, two and three dimensional pattern information from spatial frequency subsets to determine general form, edge, texture and depth information for detection, identification and classification of objects in simple or complex scenes.
