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 $L^1$ norm of the \emph{Weingarten map} of image surface $(x,y,f(x,y))$ for a given ima…
