Related Topics Configuring Blob Analyzer Properties Configuring Blob Analyzer Properties - Advanced Blob Analyzer Results 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.
