Stabilizing Omnidirectional Videos Using 3D Structure and Spherical Image Warping

This paper addresses the problem of stabilizing spherical videos. Whereas various techniques have been proposed to stabilize conventional videos, this work is the first approach proposed for omnidirectional videos. We introduce a method for extracting the camera path and 3D information of the environment. A desired smooth stabilized path is obtained by modifying the original camera path. We propose a method for synthesizing a stabilized video with respect to the desired path. Each output frame is generated by warping a single frame from the input video. Experiments on real data show that the proposed approach removes shakes and jitters from omnidirectional videos successfully.
