Select these parameters to calculate the sets of the inner and outer radii for each object. The radius at a given point of object's boundary is defined as the distance between the Centroid and the boundary point. A set of radii is obtained from a family of lines diverging from the centroid of the object at evenly spaced angles. The step between consecutive angles is defined by the Angle step option in Measurements Preferences
RadiiIn receives the array of the object's inner radii in calibrated units.
RadiiOut receives the array of the object's outer radii in calibrated units.
To access a specific element of the Radii arrays in the script, use the following syntax:
x= getParamValue("RadiiIn",i)
