The Blob Settings Window
Setting Blob Area Constraints
Area constraints define the Minimum Area and Maximum Area of valid blobs.
Area constraints are useful for separating potential blobs from background regions, or from
other blobs having similar pixel values.
All modes use Minimum Area and Maximum Area for identifying valid blobs.
Selecting the Image Segmentation Mode
The Blob Analyzer applies image segmentation to categorize pixels within the region of inter-
est as blob or background. The segmentation mode you choose depends on the nature of the
images and the relationship between blob data and background data.
All modes except the two HSL modes provide a graph used to specify bounds for the seg-
mentation. (For information on HSL, see Creating and Configuring Color Filters on page 369.)
Dark Segmentation
The Dark Segmentation mode is used to extract dark blobs on a light back-
ground.
l
All pixels with values to the left of the threshold function are potential
blob regions.
l
All pixels with values to the right of the threshold are background.
l Blobs include all pixels with a value equal to the threshold value.
