High Dynamic Range Imaging

Research topics

Video Tone Mapping, Tone Expansion and Tone Retargeting

With HDR imaging come two new technologies:

  1. Tone Mapping: compression of the dynamic range of HDR content to SDR
  2. Tone Expansion: upscaling the dynamic of a SDR content to HDR

We are involved in both topics. And more generally we are addressing scientific and technical challenges. Our main goals are to:

  1. preserve artistic intent of original HDR/SDR media when compressed/upscaled to SDR/HDR
  2. understand and model brightness comfort

Our major contributions in these domains are:
