利用MATLAB负折射率材料 导纳矩阵法(Negative refractive index materials using MATLAB admittance matrix)

这是用粒子滤波算法进行视频跟踪的源程序 初始参数已近设好了，直接运行就可以了 有兴趣的朋友可以吧它改成差帧定位 省的换个视频就要手调一次参数 为了能运算快些 算法的核心代码是用C++编的 用MEX文件转化成dll数据 在matlab中调用的 希望对大家有所参考和帮助 也希望大家有好的想法，我们一起讨论和改进 有 用粒子滤波进行视频跟踪现在国内做的还不多 需要改进的地方也很多 还需大家共同努力啊，哈哈 由于本人用的视频太大，上传了半天传不上去，只有把视频删了 下了本程序的朋友，要自己找个视频放到文件夹内 并在程序中吧读视频语句的文件名改成你所放视频的文件名 比如你视频的文件名是myvideo.avi，则程序中 video = myvideo.avi 注意视频文件的格式一定要是.avi的哦 (err)
