Abstract: | Image super-resolution as high-quality image enlargement is achieved by some type of restoration for high-frequency components
that deteriorate through the image enlargement. The estimation methods using the given image itself are effective for the
restoration, and we have proposed a method employing the codebook describing edge blurring properties that are derived from
the given image. It is, however, unfavourable to apply those image-dependent methods to movies whose scene varies momentarily.
In this paper, an image-independent codebook incorporating local edge patterns of images is proposed, and then the predefined
codebook is applied. The effectiveness is shown through some experiments. |
