Abstract

In this paper a nonlinear operator for edge detection has been proposed.It can be used fo filteringnoise and detecting edge of a given noise image at the same time. This operator has been derived frommedian filters and nonlinear Laplace operators. It is theoretically and experimentally shown that thenonlinear operator may loss very little edge information and its detection speed is quite high.
