要旨:
Tremendous progress in the development and accessibility of high dynamic range
(HDR) technology that has happened just recently results in fast proliferation
of HDR synthetic image sequences and captured HDR video. When properly
processed, such HDR data can lead to very convincing and realistic results even
when presented on traditional low dynamic range (LDR) display devices. This
requires real-time local contrast compression (tone mapping) with simultaneous
modeling of important in HDR image perception effects such as visual acuity,
glare, day and night vision. We propose a unified model to include all those
effects into a common computational framework, which enables an efficient
implementation on currently available graphics hardware. We develop a post
processing module which can be added as the final stage of any real-time
rendering system, game engine, or digital video player, which enhances the
realism and believability of displayed image streams.
