为降低随机观测矩阵在压缩感知应用中所需的存储空间,提升大尺寸图像重构的实时性,提出一种半张量 积压缩感知方法.利用该方法构建低阶随机观测矩阵,对原始信号进行全局采样,随后将测量值进行分组处理并采用 lq-范数(0 WANG JinmingYE ShipingYU LizheXU SenJIANG Yanjun ...
The fast sweeping method is an efficient iterative method for hyperbolic problems. It combines Gauss-Seidel iterations with alternating sweeping orderings. In this paper several parallel implementations of the fast sweeping method are presented. These parallel algorithms are simple and efficient due to ...
