Paper Abstract

Weighted vector median operation for filtering multispectral data is proposed. The operation shares the good qualities of vector median filters, and in addition, brings in extra freedom in the filter design. The proposed generalization of the vector median filters combines component weights, that facilitate the weighting of input signal channels separately, and distance weights that operate on the distances between the input vectors. With this structure the possible differences in the noise statistics in the different signal components can be taken into account. A number of computer simulations with color images is performed to study the properties of the new filtering scheme.
