Configuring Blob Analyzer Properties
The Blob Analyzer tool determines which areas of an image will be output as blobs by applying
Image Segmentation and Area constraints.
l The Blob Analyzer can find any number of blobs in a single image.
l Because the Blob Analyzer relies on differences in pixel grey-level (or color) values to
divide the region of interest into blob and background areas, efficient blob detection
depends on the appropriate choice of a segmentation mode.
NOTE: Before configuring the Blob Analyzer, execute the tool at least once and verify that
the tool is being positioned correctly in the image.
Segmentation Parameters
To configure Blob Settings:
1. Under the Properties section of the interface, click Segmentation Parameters.
2. Click the browse icon .
3. The Segmentation Mode window opens, as shown in the following figure.
This window provides blob constraint parameters and a graphical editor for configuring
image segmentation thresholds.
4. Set the Minimum Area and Maximum Area constraints.
These specify the area of the smallest and largest areas of valid blobs.
5. Select an Image Segmentation mode. See Selecting the Image Segmentation Mode
for details.
6. Configure the Threshold function for the selected segmentation mode. See Con-
figuring Thresholds for details.
