Detailed Description

ImageViz SoIntensityIntegralQuantification2d engine computes pixel intensity integral.

For an introduction, see section Analysis.

In the continuous case, intensity integral is defined as:

\[ V(X)=\int_{R^2}I(x,y)dxdy\]

In the discrete case, intensity integral is approximated by the sum of the pixel intensities in X:

\[ V(X)=\sum_{i,j}I(x_i,y_j)\]

where $I(x_i,y_j)$ = the intensity of pixel of coordinates $x_i,y_j$

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.
