Estimating fiber orientation distribution from diffusion MRI with spherical needlets
Hao Yan, Owen Carmichael, Debashis Paul +1
We present a novel method for estimation of the fiber orientation distribution (FOD) function based on diffusion-weighted Magnetic Resonance Imaging (D-MRI) data. We formulate the…

Geometric kernel smoothing of tensor fields
Owen Carmichael, Jun Chen, Debashis Paul +1
In this paper, we study a kernel smoothing approach for denoising a tensor field. Particularly, both simulation studies and theoretical analysis are conducted to understand the eff…
