Low-rank Tensor Recovery
Stojanac, Željka (2016-10-28)Low-rank tensor recovery is an interesting subject from both the theoretical and application point of view. On one side, it is a natural extension of the sparse vector and low-rank matrix recovery problem. On the other ... -
Processing Elastic Surfaces and Related Gradient Flows
Olischläger, Nadine (2010-07-22)Surface processing tools and techniques have a long history in the fields of computer graphics, computer aided geometric design and engineering. In this thesis we consider variational methods and geometric evolution problems ... -
Sparse Recovery with Fusion Frames
Ayaz, Ulaş (2014-07-09)Sparse signal structures have become increasingly important in signal processing applications as the technology progresses and a plethora of data needs to be handled. It has been shown in practice that various signals have ... -
Variational Discretization of Higher Order Geometric Gradient Flows Based on Phase Field Models
Franken, Martina (2013-03-21)In this thesis a phase field based nested variational time discretization for Willmore flow is presented. <br /> The basic idea of our model is to approximate the mean curvature by a time-discrete, approximate speed of the ...
