    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.
