Fast Dynamic Super-Resolution Algorithm Based on Edge Direct

A fast super-resolution (SR) algorithm is introduced in this paper which is suitable for SD to HD or UHD. Firstly, the calculation process of dynamic super-resolution (DSR) is optimized based on i-mage degradation model to re-duce the complexity and accelerate the convergence of algorithm. Then, the information of previous high-resolution frame and spatial Edge Direct Interpolation (EDI) is exploited to bate zigzag effect which appears in edge regions and accelerate convergence. Finally, the deblurring of image based on Maxim um a Posteriori (MAP) is exploited to further improve the quality of image.A-fter the test, the results show that compared with traditional methods, the PSNR is improved obviously and the running time is reduced greatly with the algorithm of this paper.
