Extension of Impulse Detectors to Spatial Dimension and their Utilization as Switch in the LMS L-SD Filter

In this paper, one kind of adaptive LMS filters based on orderstatistics is used for two-dimensional filtration of noisy greyscaleimages degraded by mixed noise. The signal-dependent adaptive LMSL-filter (L-SD) consists of two normalized constrained adaptive LMSL-filters, because they have better co...
