HDR Imaging From Differently Exposed Multiview Videos
Vikas Ramachandra, Matthias Zwicker, Truong Thao Nguyen · 2008
A procedure for obtaining high dynamic range (HDR) videos from multiple differently exposed image sequences from a camera array is explored. It is observed that using information along both viewspace (camera) and temporal axes results in a good estimate of the HDR image sequence. Images captured at longer exposures are subject to motion blur. A novel motion deblurring scheme is proposed, prior to the actual HDR mapping process. This involves a multiscale directional structure preservation procedure which uses information from adjacent views along camera-space and frames along time. The proposed deblurring scheme works in spite of illumination variations between images.
