Image Resolution Enhancement Using Spatially Invariant Point Spread Function
Kyel Ko, Myoung‐Jin Kim, Min-Cheol Hong · 2010
This paper presents an image resolution enhancement algorithm using spatially invariant point spread function. Point spread function is used to c onstrain the solution space. This parameter is computed at ea ch iteration step using partially restored image at ea ch iteration, and High pass filter is used to impose t he degree of edge smoothness on the solution. The resulting i terative algorithm exhibits the increased PSNR better than B icubic interpolation approach .
