Abstract
Image-based rendered panoramic videos are used in virtual reality user experiences commonly. Long videos recorded in situations and speed up watching by a created time-lapse video is a natural choice for users. Videos will be further shaking because of the time warping. Immersion viewing shaking videos are bring dizzy and uncomfortable for users. Our goal is the time-lapse panoramic videos stabilization. Our paper propose the first method which can perform time-lapse panoramic videos stabilization well. We propose a traditional video stabilization framework and how to use Laplacian mesh warping method to correction the parallax error of the frames first. Then we optimize the proposed framework to fit panoramic videos well. After that, we extend the basic framework by an optimized frames selection method to generating time-lapse videos. Finally, we go through our approaches and evaluation by using several input videos. Using stabilized panoramic videos in virtual reality user experiences provide good results.
