This paper addresses the problem of recovering a super-resolved image from a single low resolution input. This is a hybrid approach of single image super resolution. The technique is based on combining an Iterative back projection (IBP) method with the edge preserving Infinite symmetrical exponential filter (ISEF).It is based on IBP method combined with compensated high frequency models according to different applications. In [9], proposed we propose an estimation of HR image using IBP method integrated with high frequency information. We combine the IBP
