Enhancement and real-time analysis of an adaptive impulsive noise removal method

This paper presents the enhancement and real-time processing features of an adaptive filter for the removal of impulse noise in TV picture transmission. The basic method, which was tested on synthetic data, is first enhanced to deal with real TV pictures suffering impulse noise. Then the suitability of the method in term of real-time processing is investigated. A numerical example shows that the proposed method provides high quality solutions in much shorter time than the traditional median-type filters.
