Setting Up the Locate Blob Tool

The flow of the basic setting operation of the Locate Blob Tool is as follows.

 

  1. Add the Locate Tool to the image area.
  2. Change the tool from Locate Shape to Locate Blob.
  3. Adjust the search ROI around the blob you want to locate.

  4. Adjust the Locate Blob parameters. The parameters are the same as those of the Count Tool, which also uses Blob algorithms. See Blob Count Tool Parameters for details about settings.

  5. Train the tool to use the blob as a locator by clicking on the Train icon. The blob with the largest area is output as the detection target. A green outline is graphically displayed for the blob with the largest area. Other blobs are graphically displayed in yellow.

 


Note: The Locate Blob Tool can be enabled for ROI rotation by clicking the rotation icon at the upper left of the parameters view.
