cortex.polyutils.Surface.mean_curvature

Surface.mean_curvature()

Compute mean curvature of this surface using the Laplace-Beltrami operator. Curvature is computed at each vertex. It’s probably pretty noisy, and should be smoothed using smooth().

Negative values of mean curvature mean that the surface is folded inward (as in a sulcus), positive values of curvature mean that the surface is folded outward (as on a gyrus).

Returns:

curv1D ndarray, shape (total_verts,)

The mean curvature at each vertex.
