Abstract
A method, apparatus, and non-transitory computer readable medium for video tone mapping. The method includes receiving the video and determining parameters of a tone mapping function defined by a Bezier curve for processing the video. The method also includes generating, by at least one processor, a tone mapped video by applying the tone mapping function to the video using the determined parameters.
