Detailed Description
SoIntensityIntegralQuantification2d engine computes pixel intensity integral.
For an introduction, see section Analysis.
In the continuous case, intensity integral is defined as:
![\[ V(X)=\int_{R^2}I(x,y)dxdy\]](form_268.png)
In the discrete case, intensity integral is approximated by the sum of the pixel intensities in X:
![\[ V(X)=\sum_{i,j}I(x_i,y_j)\]](form_269.png)
where 
= the intensity of pixel of coordinates 
On a gray level image, this engine computes the sum of gray values in the image. This engine's computations take into account the pixel size.
