Modeling diffusion-weighted MRI as a spatially variant Gaussian mixture: Application to image denoising.
PURPOSE This work describes a spatially variant mixture model constrained by a Markov random field to model high angular resolution diffusion imaging (HARDI) data. Mixture models suit HARDI well because the attenuation by diffusion is inherently a mixture. The goal is to create a general model that can be used in different applications. This study focuses on image denoising and segmentation (pr...
متن کاملA spatially variant mixture model for diffusion weighted MRI: application to image denoising
High angular resolution diffusion imaging is an increasingly important image modality. The nature of the diffusion data makes mixtures of probability distributions particularly suitable for modeling its signals. In this paper, we introduce Bayesian finite mixture models for studying the diffusion field. We apply a spatially variant mixture model to study prior distributions on the model paramet...
متن کاملSURE Guided Gaussian Mixture Image Denoising
The Gaussian mixture is a patch prior that has enjoyed tremendous success in image processing. In this work, by using Gaussian factor modeling, its dedicated expectation maximization (EM) inference, and a statistical filter selection and algorithm stopping rule, we develop SURE (Stein’s unbiased risk estimator) guided piecewise linear estimation (S-PLE), a patch-based prior learning algorithm c...
متن کاملA Bayesian approach for image denoising in MRI
Magnetic Resonance Imaging (MRI) is a notable medical imaging technique that is based on Nuclear Magnetic Resonance (NMR). MRI is a safe imaging method with high contrast between soft tissues, which made it the most popular imaging technique in clinical applications. MR Imagechr('39')s visual quality plays a vital role in medical diagnostics that can be severely corrupted by existing noise duri...
متن کاملImage Segmentation using Gaussian Mixture Model
Abstract: Stochastic models such as mixture models, graphical models, Markov random fields and hidden Markov models have key role in probabilistic data analysis. In this paper, we used Gaussian mixture model to the pixels of an image. The parameters of the model were estimated by EM-algorithm. In addition pixel labeling corresponded to each pixel of true image was made by Bayes rule. In fact,...
