NONLOCALITY-BASED SUPER-RESOLUTION RECONSTRUCTION METHOD AND DEVICE

摘要

The present invention relates to a digital image enhancement art, specifically, according to the non-intensity ultra-high-resolution reconstruction relates to a method and apparatus, the sharpness of the reconstructed image is conducted in accordance with the non-intensity ultra-high resolution by the existing technology is relatively low and to solve the problem. Method according to an embodiment of the present invention, other step for deciding the search window position of the current macro block in each frame image; By in each frame image in the search window position of the macroblock corresponding to the current pixel point in the pixel block, 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 that determine the value of 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 is optimized. According to an embodiment of the present invention, it is possible to improve the sharpness of the image after reconstruction conducted according to the ratio intensity ultra-high resolution. ;
