Train Mode Train a New Color: trains a new color using the current settings
Add To The Trained Color: trains a new color using the current settings
and adds it to the Trained Color List. Pixels are in range if they are in
range for any color in the list.
Color Difference
Method
Color Difference Includes Intensity: the Maximum Allowed Color Differ-
ence value uses all 3 dimensions of color and therefore includes inten-
sity differences.This setting is faster and works well when the lighting is
controlled.
Separate Color and Intensity Differences: uses both Maximum Allowed
Color Difference and the Intensity Difference Range setting. The inten-
sity and chromaticity (hue and saturation) information is separated.
Intensity Difference Range indicates the allowed variation, plus or minus,
from the trained intensity. The Maximum Allowed Color Difference indi-
cates only the allowed chromaticity difference.
Use Red, Green, and Blue Ranges: uses the Red Range, Green Range,
and Blue Range input properties
Maximum Allowed
Color Difference
This is the maximum difference allowed between a pixel color in the
inspected image area and the Trained Color.
Intensity Difference
Range
The allowed variation, plus or minus, from the trained intensity. The
parameters are start and end.
Red Range The range used for red when Color Difference Method is set to Use Red,
Green, and Blue Ranges. The parameters are start and end.
Green Range The range used for green when Color Difference Method is set to Use
Red, Green, and Blue Ranges. The parameters are start and end.
Blue Range The range used for blue when Color Difference Method is set to Use
Red, Green, and Blue Ranges. The parameters are start and end.
Exclude Border
Blobs
When true, border blobs are excluded from the output list (see “Border
Blobs” on page 3-96)
Fill Blob Holes When true, any holes in the found blobs are filled to create a single blob.
This can save time on images with many extra blobs.
Enable Width Filter When true, blobs within the Width Range are excluded from the output
list
Width Range Blob minimum and maximum width
Enable Height Filter When true, blobs within the Height Range are excluded from the output
list
Height Range Blob minimum and maximum height. The parameters are start and end.
Enable Area Filter When true, blobs within the Area Range are excluded from the output list
Area Range Blob minimum and maximum Area. The parameters are start and end.
Required Number
of Blobs
If the number of found blobs (based on the filter settings) is within this
range, the Passed output is set to true. The parameters are start and
end.
