Apparatus and method for super-resolution enhancement processing
First Claim
1. An apparatus for super-resolution enhancement processing, the apparatus comprising:
- a low-resolution image capturing unit capturing a low-resolution image;
a patch pair generating unit dividing each of a plurality of high-resolution images into patches and generating a plurality of patch pairs composed of medium-frequency patches and high-frequency patches for the patches;
a patch pair database storing the plurality of patch pairs generated by the patch pair generating unit; and
a high-resolution image reconstructing unit dividing the low-resolution image into patches, searching in the patch pair database for a patch pair including a medium-frequency patch that is similar to that of the low-resolution image, and generating a reconstructed high-resolution image by inserting a high-frequency patch included in the found patch pair into a corresponding patch of the low-resolution image,wherein the high-resolution image reconstructing unit performs simultaneous searching of the patch pair database for a plurality of geometrically converted versions of the medium-frequency patch using a shared candidate list.

Abstract
Provided is an apparatus and method for super-resolution enhancement processing. The apparatus includes a low-resolution image capturing unit, a patch pair generating unit, a patch pair database, and a high-resolution image reconstructing unit. The low-resolution image capturing unit captures a low-resolution image. The patch pair generating unit divides each of a plurality of high-resolution images into patches and generates a plurality of patch pairs composed of medium-frequency patches and high-frequency patches for the patches. The patch pair database stores the plurality of patch pairs generated by the patch pair generating unit. The high-resolution image reconstructing unit divides the low-resolution image into patches, searches in the patch pair database for a patch pair including a medium-frequency patch that is similar to that of the low-resolution image, and generates a reconstructed high-resolution image by inserting a high-frequency patch included in the found patch pair into a corresponding patch of the low-resolution image.

10. A method for super-resolution enhancement processing, the method comprising:
-
dividing each of a plurality of high-resolution images into patches, generating a plurality of patch pairs composed of medium-frequency patches and high-frequency patches for the patches, and storing the generated patch pairs in a patch pair database; and dividing a low-resolution image into patches, searching in the patch pair database for a patch pair including a medium-frequency patch that is similar to that of the low-resolution image, and generating a reconstructed high-resolution image by inserting a high-frequency patch included in the found patch pair into a corresponding patch of the low-resolution image, wherein the searching in the patch pair database performs simultaneous searching of the patch pair database for a plurality of geometrically converted versions of the medium-frequency patch using a shared candidate list. - View Dependent Claims (11, 12, 13, 14, 15, 16)
