Abstract
A new kind of nonlinear filter, the piecewise-quadratic (PWQ) filter, is presented. This kind of filter is based on canonical PWQ functions. and enables filtering via domain partition and local processing which is particularly suitable for processing signals with various statisti cal properties such as images. The application of such a filter in res toring noisy images with Gaussian and uniform noise distributions is s hown.
