A hybrid filter for mixed noise cancellation is introduced in this paper. The proposed approach combines the advantages of the improved adaptive Wiener filter and bilinear interpolation filter, which can efficiently reduce both the white Gaussian noise and impulse noise. To s elect the corresponding filters with respect to the noise types, a novel method for impulse noise detection is also designed. Experimental and comparison results show that the proposed approach is particularly effective indoi:10.1109/icics.2003.1292504 fatcat:zsdgd4gs4jfl5ouxcgdisirf6m
