Select these parameters to compute radii of objects. The radius at a given point of object's boundary is defined as the distance between the Centroid and the boundary point. Radii are obtained by tracing all the points at the object's outside boundary or contour.
RMax returns the maximum distance from the center of gravity to the boundary.
RMin returns the minimum distance from the center of gravity to the boundary.
RAvrg returns the mean distance from the center of gravity to the boundary, or the best fit radius.
RRatio returns the ratio of the maximum radius divided by the minimum radius.
The parameters are calculated in calibrated units.
