| Abstract: | By combining the multiscale,multidirection,anisotropy and shift-invariant of Nonsubsampled Contourlet Transform（NSCT） transform and effective approach characteristic of Taylor series,this paper propose a superresolution image reconstruction algorithm,which uses Taylor series to replace double-line.Experimental result shows that the algorithm can recovery the detailed information and texture features of image,and resist Gaussian noise. |
