Built-in command

Arguments:

• amplitude[%]>=0,_sharpness>=0,0<=_anisotropy<=1,_alpha[%],_sigma[%],_dl>0,_da>0,_precision>0,_interpolation,_fast_approx={ 0:No | 1:Yes }    or
• nb_iterations>=0,_sharpness>=0,_anisotropy,_alpha,_sigma,_dt>0,0    or

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.
