Adaptive reduction of the dynamics of HDR video sequences

A new generation of acquisition devices with high dynamics is rapidly overcoming the limitations of current hardware. The dynamic range of visualisation devices is lower by some orders of magnitude with respect to acquisition hardware. Dedicated algorithms are needed to fill the gap between the high dynamics of acquired scenes and the low dynamic range of visualisation devices. We propose a novel approach to reduce adaptively the dynamics of video sequences to fit the display range. Our algorithm takes into account time relationships between neighbouring frames to avoid annoying artifacts.
