Abstract
Vector median-type filters for color video signals are introduced. In the vector median approach the samples of the vector-valued input signal are processed as vectors as opposed to componentwise scalar processing. The VM-type filters utilize the correlation between different components in video signal. Different components in the color video signal correlate strongly. If there is a change in one component, a change is also likely to happen in the other components. This makes the VM-filters attractive in video signal processing. In this paper the performance of vector median filters for color video signals are investigated. Recursive vector median filters for cross luma and cross color cancellation are presented. The vector median operation is combined with linear filtering resulting in improved cross colour and cross luma attenuation and in very good noise attenuation.
