Blob Sort Order

Once you select a Sort method, you need to define a Sort Order:

• If Position is selected for the Sort method, then Blob order is based on the x,y coordinates of the

centroids and the options are—

• Left most
• Top most
• Right most
• Bottom most

• For any of the other options, Blob order is based on Increasing or Decreasing value of the parameter

selected. For example, if Perimeter and Increasing is selected, the smallest perimeter Blob will be
Blob #1.

Blob Filter

The Blob filter allows you to more accurately select a specific Blob to locate and to use for positioning other
Vision tools. Filter modifies the Blob count based on Computed Statistics criteria so that, for example, only
circular Blobs (compactness) or symmetric Blobs (eccentricity) are included in the Blob count.

When you click the Preset button, the sensor uses the selected Blob to preset the filter values so that only the
selected Blob will subsequently be identified by the sensor. This reduces the time it would take to manually
enter values. When the sensor is in Run mode, you should use the runtime filter results to fine-tune these
settings.
