| 摘 要： | 图像超分辨率是指从一组模糊的低分辨率图像重建一帧清晰的高分辨率图像的过程.从经典的基于凸集投影POCS(projection onto convex set)的超分辨率图像重建算法出发,分析重建后高分辨率图像边缘模糊的成因,提出了一种基于保留边缘信息的POCS超分辨率图像重建算法.实验结果表明该方法能够明显地提高重建图像的质量.

| Abstract: | Super-resolution is the process of reconstructing a frame of high-resolution image from a set of low-resolution images. From the traditional high-resolution image reconstruction based on POCS algorithm, with an analysis of the blur edge of high-resolution reconstruction image included, a POCS super-resolution algorithm based on keeping the edge information is proposed. The experimental tests show that this algorithm can significantly improve the quality of the reconstruction image. |
