Paper Abstract

This paper studies pyramidal multiresolution design of aperture and W-operators for grayscale images. The multiresolution approach has been used previously to design binary filters with good results, which motivated us to extend the theory for grayscale. The initial results, theoretical and practical are also motivating.
