Advanced Edge Teach
The minimum contrast criteria for the other edge algorithms can be changed from the system default to
user-defined values if desired by using the Advanced edge teach functions. Click Advanced to display the
Advanced Edge Teach dialog box.
The contrast values of the current edge are shown in the data fields and on the graph of the edge. The low
and high edge contrast values are shown in the Edge Strength fields, and the current minimum contrast
value for edge recognition is shown in the Min Contrast field and on the graph by a green horizontal line.
Clicking the Teach button enters the minimum contrast criterion for the selected edge algorithm into the
Min Contrast field.
Typically, the edge criterion entered by the system is adequate to provide excellent edge recognition for
most applications. However, the criterion for the selected edge algorithm can be changed by entering a
new value into the Min Contrast field and then clicking OK.
