Parameter
Description
Density change
Light to Dark
Detects as an edge any position within the specified region that changes from
white to black.
Dark to Light
Detects as an edge any position within the specified region that changes from
black to white.
Measurement methods
Projection
A projection is formed based on the gray level, and any position of intersection
between the gray level value and the threshold (edge level) is detected as an
edge.
This detection method is used when you must process an image with exces-
sive noise or when the edges are blurry.
Differentiation
A differentiated waveform is created that represents the amount of change in
gray level between neighboring pixels. The maximum value of the differenti-
ated waveform that exceeds the threshold (edge level) is detected as an edge.
This detection method is used for low-contrast images.
Parameter
Setting
Description
Edge level
Range: 0 to 100
Default: 50
Set the color change level to detect as an edge.
The edge point is found based on a threshold that is set for a color change.
If you change the edge level, perform teaching again.
Edge Level
An edge is detected in the following way.
1. The color change distribution of the entire measurement region is determined.
2. The minimum color change is 0
%
. The maximum color change is 100
%
.
3. The location where the color change intersects with the edge level is detected as the edge.
