摘要：Fuzzy device for image noise reduction, comprising: interface means adapted to retrieve the gray level of a pixel to be processed of an image and of neighbouring pixels;difference means connected to said interface means adapted to generate a difference of
the gray levels between said neighbouring pixels and said pixels to be processed; fuzzy flat area smoothing means connected to said difference means adapted to perform a low-pass smoothing of an almost homogeneous region defined by said pixel and by said neighbouring pixels; edge preserving smoothing means connected to said difference means adapted to perform low-pass filtering on a high-pass information region defined by said pixel and by said neighbouring pixels; region voter means connected to said interface means adapted to give a measure for considering whether said region defined by said pixel and said neighbouring pixels is almost homogeneous; and soft switching means connected to the outputs of said smoothing means adapted to perform the weighting of the said outputs of said smoothing means on the basis of said measure.
