A Preconditioned Alternating Minimization Framework for Nonconvex and Half Quadratic Optimization
Shengxiang Deng, Ismail Ben Ayed, Hongpeng Sun
For some typical and widely used non-convex half-quadratic regularization models and the Ambrosio-Tortorelli approximate Mumford-Shah model, based on the Kurdyka-Łojasiewicz analys…
Variational Image Motion Estimation by Accelerated Dual Optimization
Hongpeng Sun, Xue-Cheng Tai, Jing Yuan
Estimating optical flows is one of the most interesting problems in computer vision, which estimates the essential information about pixel-wise displacements between two consecutiv…
Efficient ADMM and Splitting Methods for Continuous Min-cut and Max-flow Problems
Hongpeng Sun, Xuecheng Tai, Jing Yuan
The Potts model has many applications. It is equivalent to some min-cut and max-flow models. Primal-dual algorithms have been used to solve these problems. Due to the special struc…
Sparse Reconstructions of Acoustic Source for Inverse Scattering Problems in Measure Space
Xueshuang Xiang, Hongpeng Sun
This paper proposes a systematic mathematical analysis of both the direct and inverse acoustic scattering problem given the source in Radon measure space. For the direct problem, w…
On an inverse elastic wave imaging scheme for nearly incompressible materials
Li Jingzhi, Liu Hongyu, Sun Hongpeng
This paper is devoted to the algorithmic development of inverse elastic scattering problems. We focus on reconstructing the locations and shapes of elastic scatterers with known di…
On a gesture-computing technique using electromagnetic waves
Jingzhi Li, Hongyu Liu, Hongpeng Sun
This paper is concerned with a conceptual gesture-based instruction/input technique using electromagnetic wave detection. The gestures are modelled as the shapes of some impenetrab…
