| dc.description.abstract | 在虛擬實境用戶體驗中,使用基於圖片渲染的環場視訊越來越普 遍,通過縮時來觀看已經錄好的冗長的視訊则是用戶的普遍選擇。然 而,縮時會放大視訊原本就存在的抖動,沉浸式觀看抖動的視訊更會 使得用戶頭暈和不舒服。
我們的目標是產生穩定的縮時環場視訊。我們第一個提出了一種可 以獲得穩定的縮時環場視訊的方法。我們首先闡述一個基本的視訊穩 定的方法框架以及如何改進使得可以減輕視差帶來的問題。然後我們 提出適用於環場視訊穩定的方法,適用於縮時視訊穩定的方法以及縮 時環場視訊穩定的方法。最後我們回顧最終的完整的處理方法以及驗 證效果。虛擬實境用戶體驗中使用穩定的縮時環場視訊可以得到很好 的效果。 | zh_TW |
| dc.description.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. | en |
