Abstract
To utilize the full potential of new high dynamic range (HDR)
displays, a system for the enhancement of bright luminous objects in
video sequences is proposed. The system classifies clipped
(saturated) regions as lights, reflections or diffuse surfaces using
a semi-automatic classifier and then enhances each class of objects
with respect to its relative brightness. The enhancement algorithm
can significantly stretch the contrast of clipped regions while
avoiding amplification of noise and contouring. We demonstrate that
the enhanced video is strongly preferred to non-enhanced video, and
it compares favorably to other methods.
