英文摘要	In this paper, we present a novel structure preserving method for single image super-resolution to well construct edge structures and small detail structures. In our approach, the sharp edges are recovered via a novel edge preserving interpolation technique based on a well estimated gradient field and the edge preserving method, which incorporate the local and non-local structure information. The gradient of interpolated high-resolution(HR) image is then regarded as an edge preserving constraint to reconstruct the detail structures. Experimental results demonstrate that the new approach can reconstruct faithfully the HR images with sharp edges and texture structures, and annoying artifacts (blurring, jaggies, ringing, etc.) are greatly suppressed. It outperforms the state-of-the-art approaches, based on subjective and objective evaluations.; CPCI-S(ISTP); 1409-1413
