An Improved Iterative Back-Projection Algorithm for Video Super-Resolution Reconstruction

To improve the spatial resolution of the reconstructed image/video sequence and reduce the ringing artifacts, we propose an improved iterative back projection (IBP) algorithm, using the second-order differential revised term. In addition, video super-resolution segmentation reconstruction model based on a sliding window, movement registration based on a four-parameter transformation model, etc. are employed to enhance the validity of this algorithm. Experimental results show that the proposed algorithm can not only effectively reduce the ringing artifacts, well preserve the edge and texture but also enables the reconstructed image/video sequence to achiever better visual effect and resolution.
