Setting Up the Blobs Counting Tool

After selecting the tool, you will need to choose the type of region and then configure it in the image where you expect to detect the blob feature(s):

Note: When choosing blobs to use for your inspection, try to select blobs that have a high contrast between light and dark pixels.

From the Region Type drop-down menu, select the type of region: Rectangle (default), Circle, Annulus or Polygon. Position and configure the region within the image where you expect the blob(s) to appear; make sure that the boundaries of the region cover the blob(s) and their possible locations. To help the performance of the tool, create smaller regions; larger regions require longer to inspect. If you’re not using a fixture, ensure that the blob(s) are present in roughly the same location in every image, or the region is large enough to account for the expected movement of the features.

Note: After adding the tool, you can change the type of region by right-clicking the region in the image and selecting the desired shape from the Change Region to option.

Press the OK button to confirm the region (press the Cancel button to not add the tool to the job).
With the tool initially configured, load several images and adjust the tool's parameters, as needed, to compensate for your expected ranges of variations.
Finally, if desired, use the tool's Input/Output properties to share tool data between other tools and/or other external devices.
