A Robust Approach to Enhancement of Multivariate Images

Abstract

This paper addresses the problem of attenuating noise from vector-valued image data. A class of nonlinear filters stemming from robust estimation is introduced. An exact algorithm requires extensive computation. Therefore, approximate algorithms for computing the filter output are developed. The filters produce reliable results even if the assumptions on… (More)
