要旨:
The main goal of High Dynamic Range Imaging (HDRI) is precise
reproduction of real world appearance in terms of intensity levels
and color gamut at all stages of image and video processing from
acquisition to display. In our work, we investigate the problem of
lossy HDR image and video compression and provide a number of
novel solutions, which are optimized for storage efficiency or backward
compatibility with existing compression standards. To take
advantage of HDR information even for traditional low-dynamic
range displays, we design tone mapping algorithms, which adjust
HDR contrast ranges in a scene to those available in typical display
devices.
