Abstract
A 2-D adaptive nonlinear filter, namely the 2-D adaptive Volterra filter, is developed with an LMS type of adaptation algorithm. This adaptive filter is used for equalising an unknown 2-D channel with some pointwise nonlinearity and restoring images degraded by this channel. Improvements over a 2-D adaptive linear equaliser are demonstrated by experimental results.
