Abstract :
In this paper 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 will be shown that the three dimensional diffusion equation is more suitable for video sequences than the two dimensional diffusion equation
