/* NOTES
|
|
|
|
*
|
|
|
|
* The method used here is similar to the lighting invariant correctin
|
|
|
|
* method but slightly different: we do not divide the RGB components,
|
|
|
|
* but substract them I2 = I0 - I1, where I0 is the sample image to be
|
|
|
|
* corrected, I1 is the reference pattern. Then we solve DeltaI=0
|
|
|
|
* (Laplace) with I2 Dirichlet conditions at the borders of the
|
|
|
|
* mask. The solver is a unoptimized red/black checker Gauss-Siedel
|
|
|
|
* with an over-relaxation factor of 1.8. It can benefit from a
|
|
|
|
* multi-grid evaluation of an initial solution before the main
|
|
|
|
* iteration loop.

|
|
|
*
|
2011-10-18 03:47:01 +08:00
|
|
|
* I reduced the convergence criteria to 0.1% (0.001) as we are
|
|
|
|
* dealing here with RGB integer components, more is overkill.
