一种新的快速相关精跟踪算法

A novel fast and accurate correlation tracking algorithm

文中针对瞄准吊舱中前视红外成像跟踪的工作状态，提出了一种新的相关跟踪算法。该算法采用一维直方图快速搜索和二维多级亚采样精定位方案，使算法的实时实现成为可能，该算法还利用图像系列的相关性，采用隔帧修正累积误差的方法，有效地提高了系统的跟踪精度。最后，给出实验结果，结果与理论相符。

This paper presents a novel correlation tracking algorithm on the basis of the ForwardLooking Infrared Imagery tracking work state of the aimming cabin.This algorithm adoptsthe one-dimension histogram quick Search and two-dimension multistage subsample accuratepositioning methods,which make it possible to realize realtime processing.It has also effective-ly improved the System's tracking precision by frame jump modifying cumulative errors with asequence of images.Finally,this paper gives some experimental results which are in accordwith theoritical results.
