Abstract:
A method, apparatus, and non-transitory computer readable medium for video tone mapping. The method includes processing a video using at least first and second tone mapping functions to generate at least first and second tone mapped videos and identifying an amount of local contrast in one or more areas of each of the at least first and second tone mapped videos. The method further includes determining an amount of each of the at least first and second tone mapped videos to include in an output tone mapped video based at least in part on comparison of the identified amount of local contrast for each of the at least first and second tone mapped videos and generating the output tone mapped video in accordance with the determined amount of each of the at least first and second tone mapped videos.
