De-noising of Real-time Dynamic Magnetic Resonance Images by the Combined Application of Karhunen-Loeve Transform (KLT) and Wavelet Filtering
A hybrid filtering method called Karhunen Loeve Transform-Wavelet (KW) filtering is presented to de-noise dynamic cardiac magnetic resonance images that simultaneously takes advantage of the intrinsic spatial and temporal redundancies of real-time cardiac cine. This new image filtering technique …

Non-linear reduced order modeling for transport dominated fuid systems
… first part of this thesis addresses non-linear adaptive wavelet-filtering of flow systems to adjust the computational resources to the co-moving reference frame, already when generating the data. To enable MOR with the utilized adaptive data structure, a wavelet-based adaptive version of the …

Performance of Microcalcification Detection Algorithms
… microcalcifications in mammograms. First, is a wavelet based technique which applies an adaptive wavelet filter to the input mammogram. Then it calculates HOS (Higher Order Statistics) values for maxima locations that are determined from the input image by an empirical method. This is followed …
