Abstract
The present disclosure discloses an image super-resolution reconstruction method, comprising the steps of: performing an edge detection on low-resolution images to be processed to obtain edge pixel frames, amplifying the edge pixel frames so that each amplified image is the double of the original edge pixel frame in size in both horizontal direction and vertical direction, without changing the detected edge pixel information, and compensating for the interpolated interpolation pixels according to different pixel edges to obtain a high-resolution image. The method can ensure the definition and integrity of the edges, and enhance the contrast without degrading image quality. At last, the previous interpolation pixels are compensated according to optimized rules, during which influences of edge pixels and surrounding pixels are comprehensively considered, so as to eliminate the sawtooth phenomenon of the output image.
