Finally, an output image signal G(i, ) is given in Eq. (17).
j
Direction is given in Eq. (18).
Now we present an example.
An input signal is as follows:
"1 1 2
1 2 2
2 2 3_
are as
AjqO',/), AyiO',,/), G(i,/), and 6(1,7) follows:
Ay,(U) = 4
GO,7) = W2
9(/,y)= tan" 1 (4/4) = 45°
In general A* n and Ay n are as follows:
where n < ij < N- n - 1.
Finally, an output image signal GO",/) is as given in Eq. (21).
The direction angle 60",/) is given in Eq. (22).
