Blobtrack 运行
例程的命令行参数传递规则：
blobtrack.exe [fg=<fg_name>] [bd=<bd_name>]
[bt=<bt_name>] [btpp=<btpp_name>]
[bt_corr=<bt_corr_way>]
[trackgen=<btgen_name>]
[track=<track_file_name>]
[scale=<scale val>]
[noise=<noise_name>] [IVar=<IVar_name>]
[res=<res_file_name>] [FGTrainFrames=<FGTrainFrames>]
<yml_file video1 video2 video3>|<avi_file>
blobtrack的各模块CvFGDetector，CvBlobDetector，CvBlobTracker，CvBlobTrackGen，CvBlobTrackPostProc，CvBlobTrackAnalysis中有许多内部参数可以初始化(否则将用缺省值)。通过命令行参数初始化这些模块的参数的格式分别为：
[fg:<参数名1>=<参数值1>] [fg:<参数名2>=<参数值2>]
[bd:<参数名1>=<参数值1>] [bd:<参数名2>=<参数值2>]
[bt:<参数名1>=<参数值1>] [bt:<参数名2>=<参数值2>]
[btgen:<参数名1>=<参数值1>] [btgen:<参数名2>=<参数值2>]
[btpp:<参数名1>=<参数值1>] [btpp:<参数名2>=<参数值2>]
[bta:<参数名1>=<参数值1>] [bta:<参数名2>=<参数值2>]
当以这种方式从命令行输入参数时，set_params()函数便会把参数值赋值到相应模块的相应参数。例如CvFGDetector中有个参数是char * alpha1,设需要处理的avi文件位于D:\test.avi，则我们在命令行键入如下命令:
blobtrack.exe bt=test_bt.avi D:\test.avi fg:alpha1=3.14
则运行程序blobtrack.exe，对D盘的test.avi视频进行运动跟踪处理，并将CvFGDetector模块的内部参数alpha1用3.14来初始化。实际上，各个模块的内部参数很多，具体的可以通过语句“ char* param = pM->GetParamName(j); ”来查询。
以上大约是opencv1.0的，我在用opencv2.0。写下
myblobtrack fg=FG_1 bd:Hmin=0.05 bd:Wmin=0.05 btavi=test_bt.avi 2.avi
我自己暂时用的就是运行myblobtrack.exe,对2.avi进行处理，将blobentrance detection的模式最小长宽改为0.05，写test_bt.avi 文件做输出。
