CvSVM的用法

#include "cv.h"
#include "highgui.h"
#include "cxcore.h"
#include <ml.h>
#include <stdio.h>

using namespace std;int main()
{

	float label[6]={1,1,1,2,2,2};
	float traind[6][2]={{170,60},{175,65},{180,70},{155,45},{160,45},{157,50}};
	float testd[2]={175,65};

	CvMat matl,matd,mtestd;
	cvInitMatHeader(&matl,6,1,CV_32FC1,label);
	cvInitMatHeader(&matd,6,2,CV_32FC1,traind);
	cvInitMatHeader(&mtestd,1,2,CV_32FC1,testd);
	
	CvSVM svm=CvSVM();
	svm.train(&matd,&matl,NULL,NULL);
	float f = svm.predict(&mtestd);
	printf("f:  %d\n", int(f));

	return 0;
