SoInertiaMomentProcessing2d measures the resistance of an object to changes in its motion around a given axis of rotation.
This class computes a measure of an object's resistance to changes in its rotational motion. The moment of inertia of an object on a given axis describes how difficult it is to change its angular motion around that axis.
For a point mass m the moment of inertia I is simply m times the square perpendicular distance r from the axis of rotation:
On a digital image a pixel intensity can be considered as a mass. Then for an object of a binary image, m is a constant equal to 1. Thus, the moment of inertia is the sum of the square perpendicular distances from the axis:
Where:
The rotation axis is defined by a point (rotationCenterX and rotationCenterY) and an orientation (rotationAngle).
