ENH: Drop FSL BET to estimate the "outskin" (head) mask #1105

Closed oesteban closed 1 year ago

oesteban commented 1 year ago

This PR contributes toward #1032 by eliminating the need for FSL BET. This implementation requires Dipy for the nonlinear means denoising.

BTW - the nonlinear means denoising could be leveraged to calculate the sigma of the snr calculations more precisely, obtaining much better estimates.

By using an implementation closer to the gradient-based of (Mortamet, 2009), there is no more need for BET.
