Image reproduced adaptively for low ambient light (dark room scenario -- left) and high ambient light (sunlight scenario -- right). The display adaptive tone mapping can account for screen reflections when generating images that optimize visible contrast.
We propose a tone mapping operator that can minimize visible contrast distortions for a range of output devices, ranging from e-paper to HDR displays. The operator weights contrast distortions according to their visibility predicted by the model of the human visual system. The distortions are minimized given a display model that enforces constraints on the solution. We show that the problem can be solved very efficiently by employing higher order image statistics and quadratic programming. Our tone mapping technique can adjust image or video content for optimum contrast visibility taking into account ambient illumination and display characteristics. We discuss the differences between our method and previous approaches to the tone mapping problem.
The operator is available as a part of the pfstmo/pfstools package. To download the source code, go to the Source Forge file release page and download the latest release of pfstmo (and pfstools if you do not have them installed). To compile the operator you need to install GSL library and header files.
