Survey of Temporal Brightness Artifacts in Video Tone Mapping

Abstract : High Dynamic Range video acquisition and display are now achievable thanks to recent advances in the HDR field. Tone Mapping Operators convert HDR images to Low Dynamic Range ones. However, most of these operators were designed for images and do not take into account the temporal consistency inherent in a video sequence. Consequently, the appearance of temporal artifacts impairs the quality of the tone mapped video content. We propose, in this article, to classify temporal artifacts into different types: flickering, temporal contrast and object incoherency. Then, we describe some techniques designed to solve these issues and the temporal artifacts that they generate. Finally, we conclude by differentiating the interactive and automatic tone mapping requirements.
