Total Variation Regularized Iterative Back-projection Method for Single Frame Image Super Resolution
Iterative back-projection (IBP) technique is commonly used to minimize the super resolution (SR) reconstruction error and acquire a high spatial resolution image with appealing visual effect.However,the IBP based SR method suffers from the chessboard and ringing effect around edges.In this paper,we employ total variation (TV) as a part of penalty function to minimize the reconstruction error,which helps to avoid acrossedge smoothing and suppress the above-mentioned artifacts simultaneously.The experimental results validate that the proposed algorithm can promote the SR reconstruction precision considerably.
