摘要

本文介绍了一种对缓慢运动（＞０．１象素／帧）的斑点目标质心进行高精度跟踪的方法．该法通过对图象序列中目标质心位置和帧间位移测量误差的分析，提出了改进的滤波模型，有效抑制了图象空间量化噪声和灰度噪声的影响，获得了高精度的斑点目标运动参数．

Abstract

A new centroid tracking method with high accuracy for small and slowly moving target is presented It is based on measurements of target image centroid position and offset from image sequenccs. An improved filtering model is proposed for real time processing of the measurement data to reduce the effect of image intensity and discretization noise. Subpixel tracking accuracy is achieved.
