Interactive tone mapping for high dynamic range video
Abstract:
A user interactive video tone mapping method is provided that can be used for the tone reproduction of high dynamic range (HDR) content on low dynamic range (LDR) displays. The method comprises the steps of selecting a frame of a video sequence; providing a user interface for a user to manually apply scribble marks to the frame; manually applying N scribble marks to the frame, N being a whole number of value 1 or greater; and tone mapping the video sequence responsive to the scribble marks.
