Select these parameters to compute the major and minor axes of the equivalent ellipses of objects. The equivalent ellipse is defined as an ellipse that has the same moments of inertia as the corresponding object. The technique utilized in computations of binary moments depends on the type of measurements. In Blob Measurements the pixel-based algorithm is used, while in Contour Measurements the integration of area under the object's outline is performed.
AxisMajor returns the major axis of the object's equivalent ellipse in calibrated units.
AxisMinor returns the minor axis of the object's equivalent ellipse in calibrated units.
Aspect returns the ratio of the major axis divided by the minor axis.
