A three dimensional anisotropic diffusion equation is proposed to remove noise in video sequences. The three dimensional anisotropic diffusion equation utilizes the fact that consecutive frames of high correlation can be obtained in video sequences. It is shown that the three dimensional diffusion equation gives better results than the two dimensional diffusion equation which only deals with still images and slowly smoothes the edge boundaries
