A Novel Approach for Statistical Estimation of HARDI Diffusion Parameters from Rician and Non-Central Chi Magnitude Images
Introduction: The statistics of noisy MRI magnitude and root sum-of-squares (SoS) images are accurately modeled by the Rician and non-central chi (NCC) probability distributions, respectively [1]. In diffusion MRI (dMRI), the noise bias introduced by these distributions leads to distortion of estimated quantitative diffusion parameters [2]. One approach to addressing this noise bias is to denoi...
متن کاملRobust Rician noise estimation for MR images
In this paper, a new object-based method to estimate noise in magnitude MR images is proposed. The main advantage of this object-based method is its robustness to background artefacts such as ghosting. The proposed method is based on the adaptation of the Median Absolute Deviation (MAD) estimator in the wavelet domain for Rician noise. The MAD is a robust and efficient estimator initially propo...
متن کاملA Majorize-minimize Line Search Algorithm for Barrier Function
Criteria containing a barrier function i.e., an unbounded function at the boundary of the feasible solution domain are frequently encountered in the optimization framework, in particular in interior point methods for constrained optimization. Barrier function has to be carefully handled in the optimization algorithm. When an iterative descent method is used for the minimization, a search along ...
متن کاملA Majorize-Minimize line search algorithm for barrier functions
Criteria containing a barrier function i.e., an unbounded function at the boundary of the feasible solution domain are frequently encountered in the optimization framework. When an iterative descent method is used, a search along the line supported by the descent direction through the minimization of the underlying scalar function has to be performed at each iteration. Usual line search strateg...
