a) Original dataset. b,c) Magnitude data denoising by b) MPPCA; c) adapting GSVS. d,e) Complex data denoising by d) adapting MPPCA; e) GSVS. Top: denoising results in an exemplary slice and orientation at $b=10\text{ms}/\mu {\text{m}}^2$. Mid and bottom: estimates of the spherical harmonic power for the same shell and slice respectively for orders $l=0$ and $l=8$. All results correspond to the optimal aspect ratio $\hat{\gamma }=0.85$.
