Abstract
This paper presents a new method for suppressing noise in video sequences. The filter is an extension of the sigma filter. It uses local measurements to obtain noise reduction while preserving the image edges and details. By using a special defined weighting function, this filter can reduce both Gaussian and impulse noise effectively.
