一种快速稳定的对比度跟踪方法

A Fast and Stable Contrast Tracking Method

基于峰值的对比度跟踪方法是军事应用中最常用的目标跟踪方法之一。在分析了该传统方法的不足之后,提出了新的快速稳定的对比度跟踪方法。本文方法利用积分图像大幅减少重复计算,从而加快了寻找峰值的速度;同时,本文方法记录了具有相同最大值或最小值的所有子窗口位置信息,利用这些信息求得目标的当前位置。实验结果表明,与传统方法相比,本文方法的跟踪结果更稳定,计算速度更快。

The contrast tracking method based on the peak is one of target tracking methods most commonly used in millitary applications.This paper proposes a new fast and stable contrast tracking method after analyzing the shortcomings of traditional methods.For the proposed method,the integral image is used to reduce the repeated calculation greatly and speed up the search for the peak.At the same time,the new method records the position information of all sub-windows with the same maximum or minimum,which is used to calculate the current position of the target.The experimental results show:compared with the traditional method,the trcking result of proposed method is more stable and the calculation speed is faster.
