pub fn simplify_tractogram(
input: &Tractogram,
opts: &SimplifyOptions,
) -> Result<(Tractogram, SimplifyStats)>Expand description
Build a new Tractogram from input with each streamline simplified
to a Catmull-Rom-fittable control polygon. Preserves the source header
(so spatial metadata round-trips) and writes the
FITTED_MARKER_KEY marker.
When opts.group is set, only streamlines belonging to that group are
kept; output groups are remapped to the new (compacted) streamline
indices.
