The cover image shows a thresholded nonwoven fabric image which was processed
by applying a coherence-enhancing anisotropic diffusion filter (see Section 5.2 for
more details). The goal was to visualize the quality relevant adjacent fibre struc-
tures, so-called stripes. The displayed equations describ e the basic structure of
nonlinear diffusion filtering in the continuous, semidiscrete, and fully discrete set-
ting. Their theoretical foundations are treated in Chapters 2–4.
