High Quality Image Interpolation via Local Autoregressive and Nonlocal 3-D Sparse Regularization
Xinwei Gao, Jian Zhang, Feng Jiang +3
In this paper, we propose a novel image interpolation algorithm, which is formulated via combining both the local autoregressive (AR) model and the nonlocal adaptive 3-D sparse mod…
Image Super-Resolution via Dual-Dictionary Learning And Sparse Representation
Jian Zhang, Chen Zhao, Ruiqin Xiong +2
Learning-based image super-resolution aims to reconstruct high-frequency (HF) details from the prior model trained by a set of high- and low-resolution image patches. In this paper…
Exploiting Image Local And Nonlocal Consistency For Mixed Gaussian-Impulse Noise Removal
Jian Zhang, Ruiqin Xiong, Chen Zhao +2
Most existing image denoising algorithms can only deal with a single type of noise, which violates the fact that the noisy observed images in practice are often suffered from more…
Improved Total Variation based Image Compressive Sensing Recovery by Nonlocal Regularization
Jian Zhang, Shaohui Liu, Debin Zhao +2
Recently, total variation (TV) based minimization algorithms have achieved great success in compressive sensing (CS) recovery for natural images due to its virtue of preserving edg…
