Multi-Camera Platform for Panoramic Real-Time HDR Video Construction and Rendering

Yusuf Leblebici, Vladan Popovic, Kerem Seyid, Ömer Cogal, Eliéva Arlette Pignat

High dynamic range (HDR) images are usually obtained by capturing several images of the scene at different exposures. Previous HDR video techniques adopted the same principle by stacking HDR frames in time domain. We designed a new multi-camera platform wh ...
