◆ apply_autocolor()

static void apply_autocolor ( dt_iop_module_t * self )

static

Optimization loop : We try to find the CDL curves that neutralize the 3 input color patches, while not affecting the overall lightness. But this is a non-linear overconstrained problem with tainted inputs, so the best we can do is a numerical optimization. To do so, we compute each parameter of each RGB curve from the input color and the 2 other parameters. Then, we loop over the previous optimization until the difference between 2 updates is insignificant. This would need a proper stopping criterion based on convergence analysis, but it would be overkill here since it should converge usually in 20 iterations, and maximum in 100. Also, the convergence has not been proven formally. For better color accuracy, we compute on luminance corrected RGB values (after the main factors corrections). To avoid divergence, we constrain the parameters between +- 0.25 around the neutral value. Experimentally, nothing good happens out of these bounds.
