Select the detection direction.
Draw a dotted-line rectangle around the search area.
In order to enhance detection performance, make the Y dimension as
short as possible.
Set the width of the edge (1 to 8) and the flat (1 to 16), as well as the
difference in the light level (0 to 255).
Select whether to employ artifact processing or not.
