the field split into two, u = u1 + u2, one penalised in its differences and one in its Laplacian, which keeps both a step and a slope: the infimal convolution of first and second order total variation

Input

smoothingLength spatial smoothing scale for the first-order part
alpha dimensionless regularisation weight, overriding smoothingLength
beta regularisation weight for the second-order part; None derives it from the smoothing length
threshold misorientation cutoff in radians; default 15*degree
eps transition scale used to regularise absolute-value penalties
maxIter maximum iteration count; default 20
tol angular stopping tolerance in radians; default 0.001*degree
