Ccd Noise Filtering Based On 3-d Pde
Suk‐Ho Lee, Moon Gi Kang · 1998
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 gives better results than the two dimensional diffusion equation which only deals with still images and slowly smooths the boundaries.
