Despite considerable progress in HDR image tone mapping for the past decade, little work has been done for HDR video. For applications such as film post-production, the capability of local tone manipulation is highly regarded by the content creators. This paper presents an interactive tone mapping scheme for HDR video sequences. It provides a simple scribble/ stroke based interface for local tone manipulation and is capable of propagating user input information throughout a video sequence by using Gaussian mixture model (GMM) and edge preserving filtering. The experimental results demonstrated its effectiveness for HDR video tone mapping as well as its flexibility for users to easily and intuitively manipulate the appearance of the video while maintaining temporal consistency. ©2010 Crown.
