Motion Blur Target Tracking Method Based on Efficient Second-Order Minimization

针对运动模糊严重时容易导致目标跟踪失败的问题,提出了基于高效二阶最小化(ESM)的模板匹配目标跟踪算法.首先提出一种运动模糊模板匹配的图像构造模型.然后引入ESM算法,在ESM算法基础上,用改进的高效二阶最小化(ESM-MB)算法跟踪运动模板.引入摄像头快门估计时间作为参数,提出了自适应不同快门速度所引起的不同的运动模糊的ESM-MB-ST跟踪算法.最后,通过真实视频序列的跟踪实验,验证了提出的ESM-MB算法及ESM-MB-ST算法具有更强的鲁棒性与实时性.

As severe motion blur will lead to the failure of target tracking, an ESM-based template matching target tracking algorithm was proposed. First, an image structure model of motion-blurred template matching was presented. Then, the ESM algorithm was introduced and motion template was tracked based on ESM-MB. Subsequently, camera shutter estimated time was introduced as a parameter and self-adaptive ESM-MB-ST tracking algorithm of motion blur caused by different shutter speed was proposed. Finally, the real video sequence tracking experiments indicated that the proposed ESM-MB algorithm and the ESM-MB-ST algorithm had a better robustness and real-time ability.
