Adaptive nonlinear filtering methods are preferred in situations when it is necessary to adapt a filter behavior for varying signal and noise statistics. In case of the impulsive noise corruption, the problem is stated often as searching for the switching function that allows reducing the filter effect only to noisy samples. Thus, the undesired smoothing of non-corrupted image areas, which results in a blurring, especially of small image structures and details, is reduced. We provide a new adaptive framework between basic vector directional filter and identity operation based on the angular multichannel definition of the Lee sigma filter.
