Abstract

This paper presents a 3-D adaptive Volterra filter with an LMS type adaptation algorithm. This filter is used for equalizing an unknown channel with some point-wise nonlinearity and restoring image sequences degraded by this channel. First a robust higher order statistics (HOS) based motion estimation method is employed. Then, a 3-D Volterra equalizer is applied. The performance of this algorithm is demonstrated using real image sequences
