Then particle filter and mean shift are combined using the model to track the infrared small target.
首先根据红外小目标的特点,建立灰度统计直方图分布模型对目标进行描述,采用基于Bhattacharyya系数定义的距离进行相似性度量,建立目标观测模型,然后通过这个模型将粒子滤波和均值位移方法结合起来,实现对红外小目标的跟踪。
Comparing the mean shift method and MSPF,we find MSPF successfully coped with partial occlusion of target in the image sequence process,and accurately carried on the track to the infrared small target.
