英文摘要image super-resolution (sr) reconstruction is essentially an ill-posed problem, so it is important to design an effective prior. for this purpose, we propose a novel image sr method by learning both non-local and local regularization priors from a given low-resolution image. the non-local prior takes advantage of the redundancy of similar patches in natural images, while the local prior assumes that a target pixel can be estimated by a weighted average of its neighbors. based on the above considerations, we utilize the non-local means filter to learn a non-local prior and the steering kernel regression to learn a local prior. by assembling the two complementary regularization terms, we propose a maximum a posteriori probability framework for sr recovery. thorough experimental results suggest that the proposed sr method can reconstruct higher quality results both quantitatively and perceptually.
