ShapeROI, which handles ROIs with separated regions, does not currently
provide a way to iterate over each region (but it easily could; it's
just not implemented).

Since you are using the Threshold to define ROIs, use the "Analyze -
Analyze Partices" first, with the desired output as separate ROIs (aka
"outlines" and tick on the checkbox "add to manager"). Then from the ROI
Manager that opens push "Measure" to measure all ROIs. Be sure to select
the proper image first, as others may have opened as a result of the
particle analysis.
