Abstract
We describe algorithms for authoring and viewing high-resolution immersive videos. Given a set of cameras designed to be aligned more or less at the same nodal point, we first present a process for stitching seamlessly synchronized streams of videos into a single immersive video corresponding to the video of the abstract multi-head camera. We describe a general registration technique on to geometric envelopes based on minimizing a novel appropriate objective function, and detail our compounded image synthesis algorithm of multi-head cameras. Several new environment maps with low discrepancy are presented. Finally, we give details of the viewer implementation. Experimental results on both real and synthetic immersive videos are shown.
