Due to the ill-posed nature of image restoration, seeking a meaningful image prior is still a
great challenge in the field of image processing. The total variation with overlapping group …

In this paper, we deal with the Cauchy image restoration problem under the maximum a
posteriori framework. We propose a novel image prior, weighted hyper-Laplacian prior with …

Magnetic resonance (MR) imaging is considered as a very powerful imaging modality in
clinical examination, but the process of image acquisition and transmission will be affected …

Multiplicative noise removal is a quite challenging problem in image denoising. In recent
years, hyper-Laplacian prior information has been successfully introduced in the image …

The blurring of crop images acquired by agricultural Unmanned Aerial Vehicle (UAV) due to
sudden inputs by operators, atmospheric disturbance, and many other factors will eventually …

In order to solve the problem of blurred license plate image in road monitoring, the PSF
estimation method based on spectrum is often used to restore the blurred license plate …

对于稀疏角度下的投影数据, 计算机断层扫描在图像重建中容易出现伪影和噪声较多的问题,
难以满足工业及医学诊断要求. 本文提出一种基于重叠组稀疏和超拉普拉斯先验的稀疏角度CT …

摘要提出一种重加权总变分与hyperGLaplacian 相结合的图像盲复原算法. 首先,
通过重加权总变分先验重建模糊图像权重的双峰分布; 然后, 利用重建后的图像估计连续且稀疏 …

For the sparse angle projection data, the problem of artifact and noise is easy to appear in
the image reconstruction of computed tomography, which is difficult to meet the …
