A class of complementary IIR filters is introduced. One of these filters can be realized as a tapped cascaded interconnection of identical allpass subfilters. The complementary fi...
— a form-preserving 2D z-domain helix transform is proposed for the synthesis of computable practical-BIBO stable 2D recursive filters computed over uniformly-spaced circular inp...
We present a locallY adaptivE Non-lInear (YENI) filter to obtain the unsharp mask of an image. The unsharp mask obtained by the YENI filter preserves the edges in the image while ...
