CalibrateRobertson
---------------------------
.. ocv:class:: CalibrateRobertson : public ExposureCalibrate
Inverse camera response function is extracted for each brightness value by minimizing an objective function as linear system.
This algorithm uses all image pixels.

MergeRobertson
---------------------------
