手持式摄像机在使用时常常会受到使用者有意无意抖动的影响,从而影响成像效果,造成录制视频的不稳定及跳动问题,尤其是在使用者在一场景中特写或者跟踪某一具体目标时,使用者通常不能准确定位到或者估计出运动目标的位置,从而造成目标在视频中位置的不稳定,造成视频的主观效果变得不理想。
为了解决这一问题,我们需要设计一种算法来识别这种无意义的运动并设法通过补偿的方式来使得场景中的目标物体保持位置稳定的状态。
手持式摄像机捕获的视频通常都会受到抖动的影响,这严重的影响视频的主观效果。

卡尔曼滤波器是一个对动态系统的状态序列进行线性最小误差估计的算法,一般用于线性系统。一般在运动跟踪领域中摄像机相对于目标物体运动有时属于非线性系统,但由于在一般运动跟踪问题中图像采集时间间隔较短,可近似将单位时间内目标在图像中的运动看作匀速运动,采用卡尔曼滤波器可以实现对目标运动参数的估计。-Kalman filter is a state sequence of linear dynamic systems smallest error estimation algorithm for lin
