The Design of Nonlinear Adaptive Filters with Application to Image Enhancement

摘要

The Volterra operations are an effective way for the exploitations of higher order statistical redundancies of signals. We present a design method for adaptive quadratic Volterra filters with application to edge detection of images. The filter is expressed as a linear combination of generalized Teager basis filters. The expression coefficients are determined by minimizing the mean square error (MSE). And some simulations are given in this article.
