正样本pos.dat内容格式如下：
D:\face\posface\pic1.bmp 1 0 0 20 20
D:\face\posface\pic10.bmp 1 0 0 20 20
D:\face\posface\pic100.bmp 1 0 0 20 20
D:\face\posface\pic1000.bmp 1 0 0 20 20
D:\face\posface\pic1001.bmp 1 0 0 20 20
D:\face\posface\pic1002.bmp 1 0 0 20 20
D:\face\posface\pic1003.bmp 1 0 0 20 20
D:\face\posface\pic1004.bmp 1 0 0 20 20
D:\face\posface\pic1005.bmp 1 0 0 20 20
D:\face\posface\pic1006.bmp 1 0 0 20 20
D:\face\posface\pic1007.bmp 1 0 0 20 20
D:\face\posface\pic1008.bmp 1 0 0 20 20
D:\face\posface\pic1009.bmp 1 0 0 20 20
命令行输入指令：
opencv_createsamples -vec pos.vec -info pos.dat -num 2707 -w 20 -h 20
感觉像是路径不对，但换了各种路径组合还是不对，大侠们帮帮忙啊！！！
