If Use Inspection Levels is not selected all found models are classified as
accepted. All models that fulfill the conditions specified for the Search
Parameters will be classified.
Limit Search Region limits the search area for the blob analysis. Only objects
within this area will be found.
Note
Tune the blob tool by pressing Search and the blob algorithm lists all the
blobs. Adjust the size threshold limit to filter out blobs that are too large
or too small. Tune other parameters if necessary..

Morphological settings:
• Erode reduces or eliminates object features, increases the thickness
of holes within an object. This operation replaces each pixel in the
image with the maximum value of the pixels and each of its eight vertical
and horizontal neighbors.
• Dilation reduces or eliminates holes within an object, increases the
thickness of an object’s features. This operation replaces each pixel
in the image with the minimum value of the pixel and each of its eight
vertical and horizontal neighbors.
• Closing eliminates holes. Preserves small features. An erosion
operation is applied to the image, followed by a dilation operation.
