Notes

• estimated orientations improved by applying a small Gaussian filter on the structure tensor (σ=1)
• parametrization computed using scaling factors as per-triangle stiffness
• tests with varying soft constraint weight s = 1, 0.1, 0.01, 0.1 and attenuation factors p = 1, 1, 1, 10
• global weight is multiplied by per-vertex weights (from structure tensor) computed as w = (1 - abs(L2) ./ max(abs(L2))).^p
