Optimally sparse approximations of 3D functions by compactly supported shearlet frames
Gitta Kutyniok, Jakob Lemvig, Wang-Q Lim
We study efficient and reliable methods of capturing and sparsely representing anisotropic structures in 3D data. As a model class for multidimensional data with anisotropic featur…

Shearlets and Optimally Sparse Approximations
Gitta Kutyniok, Jakob Lemvig, Wang-Q Lim
Multivariate functions are typically governed by anisotropic features such as edges in images or shock fronts in solutions of transport-dominated equations. One major goal both for…
