High dynamic range (HDR) imaging has been the focus of interest for scientific, technical, and artistic communities in recent years. Progress in capture and display technologies, combined with increasing availability of processing power in both professional and consumer devices, as well as the continuing drive for more photorealistic and higher quality image and video content, have attracted further attention to HDR imaging. One can argue that HDR imaging could lead to the next revolution in image and video representation, similar to past transitions from grayscale to color, standard definition to high definition, and 2-D to 3-D. This special section is composed of seven original contributions aimed at providing readers with some of the latest developments and emerging technologies in the HDR image- and video-processing chain, either at component level, underlying fundamentals, or end-to-end and system issues.
