(a) Vertical edge
(b) Vertical edge enhancement
Figure 11. Example of Edge Enhancement 2 (Vertical edge)
(a) Two-dimensional edge
(b) Two-dimensional edge enhancement
Figure 12. Example of Edge Enhancement 3 (Two-dimensional edge)
Using N, VH and E registers, a convolution of 3 x 3 size can be achieved as shown in Figure 10, Figure 11
and Figure 12. An edge image can be obtained by taking the difference between the center pixel P and
the neighbor Mn, Ms, Mw and Me.
