NONLOCALITY-BASED SUPER-RESOLUTION RECONSTRUCTION METHOD AND DEVICE

摘要

The present invention relates to digital image enhancement art, particularly non-locality second relates to a reconfiguration method and apparatus according to the high definition, sharpness of the image reconstruction is conducted in accordance with the non-intensity ultra-high resolution by the existing technology is relatively low and to solve the problem. According to an embodiment of the present invention, other steps that determine the search window of the current macro block in each frame image; By in each frame image in the search box portion of macro block pixel point is located corresponding to a current block of pixels, determine the search window of the current pixel block in each frame image, and the similarity of each pixel block and the current block of pixels in the search window, steps to confirm the value each; And by the similarity value of each pixel block, and a step for deciding each of the center pixel value of each block of pixels it is optimized. According to an embodiment of the present invention, it is possible to improve the sharpness of an image is conducted after the reconstruction of the non-intensity ultra-high resolution. ;
