摘要
本文介绍一种对运动的斑点目标灰度质心进行高精度跟踪的方法。通过对图象序列中目标质心位置和帧间位移量的测量误差分析，提出了改进的滤波模型，有效地抑制了图象灰度噪声和空间量化误差的影响，提高了斑点目标跟踪精度。
This paper presents a tracking method with high accuracy for moving blob target. The measurement errors of position and shift of target centroid between consecutive images are analysed.An improved filtering model is proposed to suppress the influence of intensity noise and sampling error. And' tracking accuracy is promoted.
