大津阈值分割法,也称最大类间方差法,利用图像的灰度分布密度函数定义图像的交叉熵。
交叉熵可看作是两个概率系统(即图像背景及目标)的信息量之间的差异。求出的交叉熵越大,则分割效果越好。

背景建模和前景分割的方式把运动车辆提取出来。并进行最近临关联,输出目标轨迹。
MeanShift运动目标跟踪 matlab程序
1.截取跟踪目标矩阵rect
2.求取跟踪目标的加权直方图hist1
3.读取视频序列中的一帧, 先随机取一块与rect等大的矩形,计算加权直方图hist2。
4.计算两者比重函数,如果后者差距过大, 更新新的矩阵中心Y,进行迭代(MeanShift是一种变步长可以迅速接近概率密度峰值的方法),直至一定条件后停止。
