We compare two recently developed statistical tractography methodologies by Carmichael and Sakhanenko [2, 3] on a series of artificial but mimicking reality datasets. Both methodologies are used to model diffusion tensor imaging (DTI) and high angular resonance diffusion imaging (HARDI), which are popular brain imaging techniques. The approach based on a higher order tensor model dominates the approach based on a standard matrix model in all scenarios including wide and narrow fibers, single and crossing fibers.
