            **What it does**

            This module can perform addition, subtraction, multiplication, division, or averaging of two or more image intensities, as well as inversion, log transform, or scaling by a constant for individual image intensities.

            Keep in mind that after the requested operations are carried out, the final image may have a substantially different range of pixel intensities than the original. CellProfiler assumes that the image is scaled from 0 – 1 for object identification and display purposes, so additional rescaling may be needed. Please see the RescaleIntensity module for more scaling options.
