public class SoInertiaMomentProcessing2d extends SoImageVizEngine
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:
- x is an object pixel
- p(x) is the orthogonal projection of x onto the axis of rotation.
The rotation axis is defined by a point (
rotationCenterX
androtationCenterY
) and an orientation (rotationAngle
).File format/default:

Field Detail
-
inBinaryImage
public final SoSFImageDataAdapter inBinaryImage
The input binary image. Default value is NULL. Supported types include: binary color image.
-
rotationCenterX
public final SoSFInt32 rotationCenterX
The X coordinate of the rotation axis. Default value is 1024.
-
rotationCenterY
public final SoSFInt32 rotationCenterY
The Y coordinate of the rotation axis. Default value is 1024.
-
rotationAngle
public final SoSFFloat rotationAngle
The orientation of the rotation axis in degrees (not radians). A positive value means that the angle is taken from the positive X axis to the postive Y axis. Default value is 10.0f.
