| 摘 要： | 本文介绍一种复杂背景中目标图像的提取与高精度目标形心跟踪算法。通过对贝叶斯（Ｂａｙｅｓ）风险函数最优化，将图像分成多灰度层次的目标与背景，进而得到多灰度阀值，并考虑目标像素之间的连通性，将图像进行二值化，有效抑制了孤立噪声点对分割的影响。根据分离后二值图像，得到了跟踪窗中目标形心估值误差表达式，进而得到一种将目标跟踪窗口不断向目标形心移动的高精度形心跟踪算法。

| Abstract: | This paper presents an algorithm for target image extraction and high precious target centroid tracking in complex environment.The division of the image into several layers of gray level is optimized by minimizing the Bayes risk.The expression of image centroid estimation error is obtained according to binary image, and then a tracking algorithm with high accuracy is developed based on the error expression. |
