Adaptive multichannel non-parametric median M-type K-nearest neighbour (AMN-MMKNN) filter to remove impulsive noise from colour images

An adaptive multichannel non-parametric median M-type K-nearest neighbour filter to remove impulsive noise from colour images is presented. This filter uses the VMMKNN algorithm combined with an adaptive non-parametric one. Simulation results indicate that the proposed filter has better restoration performance in comparison with other known colour image filters.
