smooth

Built-in command

Arguments:

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.

Examples of use:

• Example #1

image.jpg repeat 3 smooth 40,0,1,1,2 done

Command: image.jpg repeat 3 smooth 40,0,1,1,2 done
