[0017] The present invention will be further described below in conjunction with accompanying drawing:
[0018] figure 1 , based on gradient contour example dictionaries and weighted adaptive p A single image super-resolution reconstruction method of norm, comprising the following steps:
[0019] (1) For the input low-resolution image, use the bicubic interpolation method to upsample to obtain the initial high-resolution estimated image;
[0020] (2) The estimation of the high-resolution gradient image is completed by the neighborhood embedding super-resolution reconstruction method based on the gradient profile example dictionary, and the estimated high-resolution gradient image is used to construct the gradient domain prior;
[0021] (3) According to the existing high-resolution estimated image, extract the adaptive neighborhood of each reference pixel, and perform non-local similar block search to form a shape-adaptive similar block group;
[0022] (4) According to the e...
