Abstract:Digitally acquired high dynamic range (HDR) video baseband signal can take 10
to 12 bits per color channel. It is economically important to be able to reuse
the legacy 8 or 10-bit video codecs to efficiently compress the HDR video.
Linear or nonlinear mapping on the intensity can be applied to the baseband
signal to reduce the dynamic range before the signal is sent to the codec, and
we refer to this range reduction step as a baseband quantization. We show
analytically and verify using test sequences that the … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
