Abstract: This thesis addresses the problem of digital video stabilization. Videos captured by hand-held devices (e.g., cell-phones or DVs) often appear remarkably shaky. Digital video stabilization improves the video quality by removing unwanted camera motions. In this thesis, three different methods are presented. We first address video stabilization by adopting a depth camera. We show that the depth can facilitate both camera motion estimation and frame warping, thus make the video stabilization a much well posed problem. Then, we present a video stabilization approach named as bundled camera paths, in which multiple 2D camera paths are proposed to represent camera motions. Its mesh-based , spatially-variant motion representation allows us to fundamentally handle parallax issues. Finally, we present a novel motion model, SteadyFlow, which is a specific optical flow by enforcing strong spatial coherence. Our experiments demonstrate the effectiveness of our stabilization methods on real word challenging videos.
