Abstract
A signal processing device for generating an output signal corresponding to a multi-dimensional input signal such as a two-dimensional image and a method of processing such a signal. The device includes an array of processing elements which are congruent and shaped so that they can be arranged on a processing element so that adjacent pairs of elements considered as a unit are geometrically similar to each processing element. Output signals of individual processing units are linearly ordered in such a manner as to maintain adjacency of signals from adjacent processing elements in the array. The ordering facilitates one-dimensional Haar transform processing of the signals in such as a manner as to localize signal energy.
