Blind Hyperspectral and Multispectral Images Fusion: A Unified Tensor Fusion Framework from Coupled Inverse Problem Perspective
Ying Gao, Michael K. Ng, Chunfeng cui
Hyperspectral and multispectral images fusion aims at integrating a low-resolution hyperspectral image (LR-HSI) and a high-resolution multispectral image (HR-MSI) to construct a hi…

Blind Deconvolution for Color Images Using Normalized Quaternion Kernels
Yuming Yang, Michael K. Ng, Zhigang Jia +1
In this work, we address the challenging problem of blind deconvolution for color images. Existing methods often convert color images to grayscale or process each color channel sep…

A New Cross-Space Total Variation Regularization Model for Color Image Restoration with Quaternion Blur Operator
Zhigang Jia, Yuelian Xiang, Meixiang Zhao +2
The cross-channel deblurring problem in color image processing is difficult to solve due to the complex coupling and structural blurring of color pixels. Until now, there are few e…
