We have presented a set of improvements to the algorithm
that adapts the dictionary of diffusion functions,
modifying and rotating the diffusion tensor profile. Our
proposal simplifies the optimization problems using
linear approximations in the rotations and size of
diffusion profiles are estimated solving simple linear
least-squares sub-problems. We evaluated our method
performance with benchmark data set and we demonstrated
its capabilities using real data.
