cortex.polyutils.Surface.smooth

Surface.smooth(scalars, factor=1.0, iterations=1)

Smooth vertex-wise function given by scalars across the surface using mean curvature flow method (see http://brickisland.net/cs177fa12/?p=302).

Amount of smoothing is controlled by factor.

Parameters

scalars1D ndarray, shape (total_verts,)

A scalar-valued function across the cortex, such as the curvature supplied by mean_curvature.

factorfloat, optional

Amount of smoothing to perform, larger values smooth more.

iterationsint, optional

Number of times to repeat smoothing, larger values smooths more.

Returns

smscalars1D ndarray, shape (total_verts,)

Smoothed scalar values.
