Filters and shared boundary networks for smoothing reconstructed grain boundaries.

Class or function Description
boundaryFilter the base of the boundary smoothing filters: smooth(V, net, h) moves the free vertices V of a boundary network sampled at the spacing h, the fixed ones stay
laplaceFilter repeated local averaging, the default
taubinFilter smoothing without the shrinking: every smoothing pass is followed by a slightly larger unshrinking one with a negative step, so the gain over the pair, (1 - lk)(1 - mk), is about one over the low frequencies and the area is given back
curvatureFilter the smooth boundary as the minimiser of |V - V0|^2 + alpha |L V|^2, where L V is how far a vertex sits off the line through its neighbours
huberFilter smooth grain boundaries with a Huber curvature penalty that preserves sharp corners
boundaryNetwork the network the smoothing runs on: only the vertices the boundaries use, their neighbours in compressed form, and which of them may not move
