Good questions. Once the image is thresholded, the result is a binary image that consists of background values and blobs or particles of foreground values.

When processing particles, the Area size limit is used to eliminate all particles smaller than the limit. The units are in % of camera view area. Using a percentage allows it to be independent of camera resolution.

The Center and Outer are terms that refer to the 3 point and 2 point targets. The targets have different aspect ratios, and the numbers are also used to classify whether a given particle is believed to be Center or Outer.

Let me know if this is enough info.
