Abstract :
Within the last two decades a useful, nontrivial theory of nonlinear signal processing has been built around the median filter. The authors outline the development of this theory from its beginnings in the study of the noise removal properties and structural behavior of the median filter to the recently developed theory of optimal stack filtering. A recent application of stack filters to the problem of edge detection in noisy images is provided to demonstrate the effectiveness of this new theory
