Abstract
The present invention relates to a method for recovering a compressed image for an image processing technique and an apparatus therefor. In the present invention, a cost function is defined in consideration with a directional characteristic of the pixels which will be recovered and a plurality of pixels of the recovering pixels. In addition, a regularization parameter variable having a certain weight is obtained from the cost function, and the regularization parameter variable is approximated using the compressed pixel for thereby obtaining a recovering pixel. The regularization parameter variable has a weight of a reliability with respect to the original image and a weight of a smoothing degree of the original image.In the method, a pixel of an image is filtered using a filtering methodology that adjusts a degree of filtering based on a difference value. The difference value may be based on the pixel being filtered and a neighboring pixel. As an example, the neighboring pixel may be a pixel adjacent to the pixel being filtered.
