We propose a Multi-resolution Discrete Search method to
estimate white matter microstructure based on three key
ideas: 1) A Multi-resolution Discrete Search to
determine the Principal Diffusion Directions; 2) The
parameter-free determination of the number of axon
bundles using the Bayesian Information Criterion and 3)
A Simultaneous Denoising and Fitting procedure to
achieve robustness with respect to noise.
