Abstract

Many early vision tasks require the use of oriented filters; examples are texture analysis [6], noise removal [3], image compression [2], and motion estimation [1]. It is often useful to adaptively control the orientation and phase of the filtering process, in a time-variant or space-variant manner. In this paper we discuss an efficient architecture for such processing and develop flexible design methods for filters used in such a system.
