A filter is proposed for removing noise and other types of degradation. An application is explored to enhancement of frame sequences, motivated by the problem of film restoration for the movie industry. Experiments are performed on sequences from a degraded black and white copy of a recently release

โฆ Synopsis
A new anisotropic diffusion model is proposed for image restoration and segmentation, which is closely related to the minimization problems for the unconstrained total variation E(u) = .fโข (~(x)JVuJ + (jJ/2)Ju -112. Existence, uniqueness, and stability of the viscosity solutions of the equation are proved. The experimental results are given and compared with the existing models in the framework of image restoration. The improvement on preserving sharp edges by using the new model is visible.
