Adaptive Multiscale Methods for Sparse Image Representation and Dictionary Learning
(2019-01-16)In this thesis we are interested in the topic of sparse digital image representation through adaptive multiscale basis. We develop for this two numerical methods: the Region Based Easy Path Wavelet Transform and the Haardict. ... -
Application of Persistent Homology in Signal and Image Denoising
(2015-07-29)Motivated by recent developments in topological persistence for assessment of the importance of features in data sets, we study the ideas of persistence homology for one-dimensional digital signals and its application in ... -
Numerische Methoden zur Analyse hochdimensionaler Daten
(2014-09-10)This thesis is concerned with two of the major tasks in processing huge data sets, dimensionality reduction and data denoising. The first part of the thesis yields a summary on dimensionality reduction. Dimensionality ... -
Adaptive Waveletmethoden zur Approximation von Bildern
(2011-07-15)This thesis is concerned with adaptive wavelet methods for the approximation of images. First, the Easy-Path-Wavelet-Transform (EPWT) is introduced. The EPWT works as follows. We determine ...
