【Abstract】 Multi line based global motion estimation algorithm is proposed. It derives the global motion parameters from local motion parameters, which are estimated through line segment analysis, and their respective weights. Using this algorithm, the trajectory of image sequence is worked out. Comparison between original trajectory and the one that is filtered with mean value, vibration parameters are generated. Then the stable image sequence can be obtained by compensating image frames with the vibration parameters.更多还原
