Panoramic video stabilization algorithm based on spherical transformation

The acquisition of panoramic videos usually suffers from undesirable jitters due to deviations and rotations of the cameras. According to the characteristics of spherical panorama, an algorithm aimed to stabilize panoramic videos is proposed in this paper. For each frame, the algorithm estimates the Euler angle of the panoramic camera. With the mapping between spherical panorama and sphere, it then projects each panoramic frame onto a spherical surface, transforms them with the Euler angles of the camera and gets the corrected frames. The sequence of the corrected frames constitutes a stabilized video. The experimental results show that the algorithm corrects the jitters and improves the stability of panoramic video. 1548-7741/
