一种自动改变窗口尺寸的跟踪算法

摘要

A practical tracking system is required to update the appearance change of moving objects while the moving object is tracked. In order to solve the problem that CamShift algorithm could not catch the distinct scale change target inaccurately. The search window size is predicted based on original algorithm in this paper,and also the object centroid position. Experimental results demonstrated that the improved algorithm could select the proper size of the tracking window in the scenarios that not only the object scale increases but the scale decreases as well.%在动态目标跟踪过程中,实用的跟踪系统要求能实时地适应运动目标的外观变化,为了解决CamShift算法在跟踪尺度变化的目标的不准确问题,本文在原算法基础上预测搜索窗口的尺寸,同时也对运动目标质心位置进行预测.实验结果表明,改进的算法对尺寸逐渐逐渐增大的目标都能自动选择合适的跟踪窗口大小.
