| Summary: | Color images are typical examples of vector-valued signals. For thatreason, vector processing represents an optimal approach. Althoughwidely used vector filter is a vector median based on a reducedordering, the directional processing with utilizing of the anglebetween input vectors can be used, too. By this way can be achievedwell estimates, since vector directional filters preserve colorchromaticity, whereas vector median filters may not satisfy thisrequirement. So, this paper is focused on the performance of basicvector directional filter in dependence on the various angle distances. |
