Color video signal processing with median filters

Methods of applying median filtering for three-dimensional video signals were studied and are compared. Median operation and RGB- versus YUV-domain processing are discussed. An introduction to various ordering methods in median-based multidimensional filtering is given. The various 3-D median processing methods and the effect of the conversion from the RGB to the YUV domain were tested. The signal processing methods used for testing were noise reduction and interlaced-to-progressive conversion. The test results are given.<
