feedback algorithm with “infinite” gain in the loop (simulation)

          The feedback was simulated with K=50000 (see p.5). It was sufficient to achieve perfect discounting the illumination.

The feedback algorithm with amplification in the loop performs perfect colour constancy: returns output images which do not depend on the illumination.
