10. Take the anisotropic diffusion scheme (see Section 7.8):
I
1 + [ I / T ] 2
∂φ
t = div
.
Show that if I < T, the edges are blurring and if I > T they become
sharper.
11. Let us suppose h and g as constants in the GVFmodel given by the equation:
u
t = g u + h ( f u ) .
Consider the stationary solution and take the Fourier transform of the
corresponding stationary equation to analyze the GVF in the frequency
space.
