### Setting Up the Blob Count Tool

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

1. Add a Count Tool to the image area.
2. Adjust the measurement area to cover the area where you expect the object to move. For best results, make this ROI as large as possible.
3. The outline information of detected blobs is displayed graphically. If the intended blob is not detected, adjust the blob selection, threshold, image preprocessing, etc. See the Blob Count Tool Parameters section for configuration details.
4. Acceptance criteria can be set for the number of detected blobs. See the judgment condition section of the Blob Count Tool Parameters.

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

Precautions for Correct Use: When switching between Blob Count and Shape Count, the links between tool outputs and GDS tags are lost. This is because the underlying components that make up the Count Tool are completely removed and then recreated whenever you change the tool’s capability.
