SVD update methods for large matrices and applications
Juan Manuel Peña, Tomas Sauer
We consider the problem of updating the SVD when augmenting a "tall thin" matrix, i.e., a rectangular matrix $A \in \RR^{m \times n}$ with . Supposing that an SVD of i…
Generalized Taylor operators and Hermite subdivision schemes
Jean-Louis Merrien, Tomas Sauer
Hermite subdivision schemes act on vector valued data that is not only considered as functions values in , but as consecutive derivatives, which leads to a mild form…
A space-based method for the generation of a Schwartz function with infinitely many generalized vanishing moments with applications in image processing
Thomas Fink, Uwe Kähler
In this article we construct a function with infinitely many vanishing (generalized) moments. This is motivated by an application to the Taylorlet transform which is based on the c…
Level-dependent interpolatory Hermite subdivision schemes and wavelets
Mariantonia Cotronei, Caroline Moosmüller, Tomas Sauer +1
We study many properties of level-dependent Hermite subdivision, focusing on schemes preserving polynomial and exponential data. We specifically consider interpolatory schemes, whi…
