Automatic image restoration.

Our method performs a frequency decomposition of the input image. The
frequency decomposition parameter is decided according to the standard
deviations of the autocorrelation matrices of the input image.
Lower frequency part of the image is reconstructed with solving a
partial differential equation. This PDE reconstruction method restores
some global structures in a picture like some shadows.
Higher frequency part of the image is reconstructed by non-parametric
texture synthesizing method.
