Spatially Adapted First and Second Order Regularization for Image Reconstruction: From an Image Surface Perspective
Qiuxiang Zhong, Ryan Wen Liu, Yuping Duan
In this paper, we propose a new variational model for image reconstruction by minimizing the norm of the \emph{Weingarten map} of image surface for a given ima…

Image Reconstruction via Discrete Curvatures
Qiuxiang Zhong, Ke Yin, Yuping Duan
The curvature regularities are well-known for providing strong priors in the continuity of edges, which have been applied to a wide range of applications in image processing and co…
