A fast video stitching method for motion-compensated frames in compressed video streams

摘要

We propose a fast video stitching method based on global motion tracking for motion-compensated frames, which can construct high definition or panorama video from standard definition video streams. Our method consists of two stages. The first stage calculates projection matrix between stitched frames coarsely by compensating for global motion of each input video stream. Since the result of the first stage may include some matching error, fine adjustment is performed in the second stage.
