Bridging the ensemble Kalman filter and particle filters: the adaptive Gaussian mixture filter
(Peer reviewed; Journal article, 2010)The nonlinear filtering problem occurs in many scientific areas. Sequential Monte Carlo solutions with the correct asymptotic behavior such as particle filters exist, but they are computationally too expensive when working ... -
Hierarchical Bayesian Survival Analysis of Age-Specific Data From Birds' Nests
(Master thesis, 2010-11-19)In this thesis, I first present the grassland birds data from Wells(2007) which is used by several different methods of estimating the nest survival rates. The hierarchical Bayesian method from Cao(2009) then is introduced ... -
On Semi-implicit Splitting Schemes for the Beltrami Color Image Filtering
(Peer reviewed; Journal article, 2011)The Beltrami flow is an efficient nonlinear filter, that was shown to be effective for color image processing. The corresponding anisotropic diffusion operator strongly couples the spectral components. Usually, this flow ...
