| Abstract: | Video processing techniques using true 3D transforms are largelyunexploited, partly because of the drawbacks of traditionalseparable 3D transforms. In this paper we use a new type ofnon-separable 3D wavelet transform for video denoising andovercome the motion-mixture problem by using oriented complexwavelets. This wavelet transform is a 3D version of Kingsbury's 1D and 2D dual-tree wavelet transforms. We also investigate video denoising techniques using a combination of both 2D and 3Doriented wavelet transforms. The results are compared with thoseobtained by separable wavelet transforms. | ||
