摘要:
提出了基于多直线特征的全局运动估计算法,该算法利用直线段来估计局部区域的运动参数,再根据局部运动参数和相应的权系数估计全局运动参数.作为应用,采用平均值滤波法对图像序列轨迹进行了滤波.通过比较滤波前后的运动轨迹,计算出图像序列中帧的抖动参数; 并利用补偿技术对图像帧进行抖动补偿,获得了稳定的图像序列输出.
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.
