A Two-Dimensional Haar-Like Transform

Abstract

The report concerns a transform based on a set of two-dimensional Haarlike functions. Series expansions of two-dimensional functions in terms of this set have convergence properties that are analogous to those of Haar series. Following a brief review of Haar functions, the two-dimensional functions are defined and their properties discussed. Analog and digital transforms based on these functions are then considered. Possible applications are image coding and pattern recognition.
