Fast and Robust High Dynamic Range Image Generation with Camera and Object Movement
Thorsten Grosch · 2006
High dynamic range (HDR) images play an impor-tant role in todays computer graphics: Typical ap-plications are the improved display of a photograph with a tone mapper and the relighting of a virtual object in a natural environment using an HDR en-vironment map. Generating an HDR image usually requires a sequence of photographs with different exposure times which are combined to a single im-age. In practice two problems occur when taking an image sequence: The camera is moving or ob-jects are moving during the sequence. This results in a blurry HDR image due to the camera move-ment and moving objects appear multiple times as ghost images in the combined image. In this paper,
