Description:
Smooth selected images anisotropically using diffusion PDE's, with specified field of
diffusion tensors.
interpolation can be
{ 0:nearest | 1:linear | 2:runge-kutta }.
Default values:
sharpness=0.7, anisotropy=0.3, alpha=0.6, sigma=1.1, dl=0.8, da=30, precision=2, interpolation=0 and fast_approx=1.
This command has a tutorial page.
