In dynamic planar imaging, extraction of signals specific to structures is complicated by structures superposition. Due to overlapping, signals extraction with classic regions of interest (ROIs) methods suffers from inaccuracy, as extracted signals are a mixture of targeted signals. Partial volume effect raises the same issue in dynamic tomography. Source separation methods, such as factor analysis of dynamic sequences, have been developed to unmix such data. However, the underlying problem is…

Spatially Constrained Online Dictionary Learning for Source Separation
A spatially constrained dictionary learning source separation algorithm that uses e.g. high resolution segmentation map or regions of interest defined by an expert to regularise the source contribution estimation and is easily adaptable to different applications by adding or modifying the constraints on the sources properties in the optimisation problem.
Bayesian Non-Negative Matrix Factorization With Adaptive Sparsity and Smoothness Prior
This work forms the problem using a probabilistic model and estimates all its parameters using the variational Bayes method, using the fact that the assumptions of sparsity and smoothness are different forms of prior covariance matrix modeling to avoid ad hoc combination of these assumptions using weighting coefficient.
Low-Element Image Restoration Based on an Out-of-Order Elimination Algorithm
An image restoration method for underdetermined blind-source separation based on an out-of-order elimination algorithm and the fast independent component analysis (FastICA) algorithm is proposed, which can effectively and completely extract all the source signals.

Factor Analysis of Dynamic Sequence with Spatial Prior for 2D Cardiac Spect Sequences Analysis
A new objective function using soft spatial prior knowledge is developed for unmixing SPECT sequences and its efficiency and robustness to the choice of priors are illustrated with tests on synthetic dataset.
Bayesian Blind Separation and Deconvolution of Dynamic Image Sequences Using Sparsity Priors
A novel blind source separation method based on probabilistic model of dynamic image sequences assuming each source dynamics as convolution of an input function and a source specific kernel (modeling organ impulse response or retention function) and solved by the Variational Bayes method.
