Comments Off on Image Super-Resolution Based on Structure-Modulated Sparse Representation
Posted in: IEEE 2017, MATLAB
Image Super-Resolution Based on Structure-Modulated Sparse Representation ABSTRACT: Sparse representation has recently attracted enormous interests in the field of image restoration. The conventional sparsity-based methods enforce sparse coding on small image patches with certain constraints. However, they neglected the characteristics of image structures both within the same scale and across the different scales for the […]

Comments Off on Image Denoising by Exploring External and Internal Correlations
Posted in: IEEE 2017, MATLAB
Image Denoising by Exploring External and Internal Correlations ABSTRACT: Single image denoising suffers from limited data collection within a noisy image. In this paper, we propose a novel image denoising scheme, which explores both internal and external correlations with the help of web images. For each noisy patch, we build internal and external data cubes […]
