public class SoAreaQuantification2d
extends SoImageVizEngine

SoAreaQuantification2d engine SoAreaQuantification2d computes the area of the pixels object. For an introduction, see section Image Analysis.

In the continuous, or theoretical, case, area is defined as:

In the discrete, or actual, case, area is approximated by the number of pixels in X:

Where :

The area measure can be weighted by a size factor which characterizes the area of a single pixel. In which case, the measure is physically homogeneous to the area.

On a binary image, this module returns the number of non zero pixels in the image. Computed area takes into account pixel size.
