Diffusion weighted magnetic resonance imaging is widely used in the study of the structure of the fiber pathways in brain white matter. In this work we present a new method for denoising intra---voxel axon fiber tracks. In order to improve local (voxelwise) estimations, we use the general---purpose segmentation method called Entropy---Controlled Quadratic Markov Measure Field Models. Our proposal is capable of spatially---regularize multiple axon fiber orientations (intra-voxel orientations). In order to provide the best as possible local axon orientations to our spatial regularization procedure, we evaluate two optimization methods for fitting a Diffusion Basis Function model. We present qualitative results on real human Diffusion Weighted MRI data where the ground---truth is not available, and we quantitatively validate our results by synthetic experiments.
