摘要
采用时一空梯度法,建立一种估计图像序列中目标偏移值的相关跟踪算法。该算法采用一维相关,而且两个方向相关运算可以并行独立运算,适于硬件实现,计算速度大大高于常规相关跟踪算法,具有很强的实时性,仿真结果还表明该算法具有较高跟踪精度,且对噪声不敏感。
This paper develops a realtime correlation tracking algorithm based on the spatio-timporal gra- dient method for estimating the displacement.Only one dimensional correlation is employed and the caculation on two directions is parallel and independent.The properties make it easy to design and implement it in a highly parallel fashion.The speed is highly superior to the speed of conventional correlation algorithm.The simualtion results show the algorithm has good tracking performance and good noise immunity.
