Digital Video Stabilization Based on Block Motion Estimation

This paper presents a video stabilization algorithm based on block motion estimation. The proposed digital video stabilization (DVS) system is composed of motion estimation unit and motion correction unit. Motion estimation unit is based on block matching to estimate global motion parameters and motion correction unit is based on the correcting motion parameters needed to compensate for the jitter and finally warp the image to output a stabilized sequence. The experiments show the performance and correcting reliability of this algorithm.
