High Dynamic Range Image and Video Processing

Tremendous progress in the development and accessibility of high dynamic range (HDR) technology that we witness in recent years creates many interesting opportunities and challenges in computer vision, image processing and graphics.

The goal of this web page is to provide information on a complete pipeline for HDR image and video processing from acquisition, through compression and quality evaluation, to display. We include links to relevant papers and project pages.

We also provide source code of tools useful for HDR image and video manipulation. Finally, we give successful examples of the use of HDR technology in research setups and industrial applications.
