Adaptive filtration of the colour images with the generalized Distance Directional Filter using the modified HSV colour space

In the paper some possibilities of using the HSV colour space for the multichannel nage filtering are analysed. The most typical problem with the hue component is its circular character, so for the adaptive filtration the appropriate choice of the "starting" point, known from the conditional ordering, is proposed. Such approach can be useful also or some other colour median filtering methods such as Vector Median Filter, Basic Vector Directional Filter or their combination known as the Distance-Directional Filter. The results of the filtration performed using the most popular methods with the usage of such modified HSV colour space have been compared to the effects of using standard HSV and RGB colour spaces.
