OpenCV中CV_SVM中单类如何实现代码？

Question

我现在想利用CV_SVM中的ONE_CLASS进行单类分类方法，但是又不知道该怎么样使用函数以及具体参数的设置。
以下是我参照多类别分类的代码，但是运行时报错，希望懂得人给点指导。

#include "stdafx.h"
#include
#include
#include
#include
#include

using namespace std;

int main(int arg,char **argv)
{
const int s=1000;
int size= 400;
int i,j,svm_num;

IplImage *img;
img = cvCreateImage(cvSize(size,size),IPL_DEPTH_8U,3);

cvZero(img);

CvSVM svm = CvSVM();
CvSVMParams param;
CvTermCriteria criteria;

CvRNG rng = cvRNG(time(NULL));
CvPoint pts[s];
float data[s*2];

float space[s*2];
int res[s];

CvMat data_mat,res_mat;
CvScalar rcolor;
const float *support;

int n=0;
for (i=0; i<s; i++)
{
    pts[i].x = cvRandInt(&rng) %size;
    pts[i].y = cvRandInt(&rng) %size;
    if ((pts[i].y > 50 && pts[i].y < 100) && (pts[i].x >50 &&pts[i].x<100)) //根据指定位置设定想要的范围，这些也是仅有的正样本。
    {
        cvLine(img, cvPoint(pts[i].x - 2,pts[i].y-2), cvPoint(pts[i].x+2,pts[i].y+2),CV_RGB(255,0,0));
        cvLine (img, cvPoint (pts[i].x + 2, pts[i].y - 2), cvPoint (pts[i].x - 2, pts[i].y + 2), CV_RGB (255, 0, 0));
        res[n] =1; //记录样本
        space[n*2] = float(pts[i].x)/size; 
        space[n*2 +1] = float(pts[i].y)/size;
        n++;
    }
    else
    {
        cvLine(img, cvPoint(pts[i].x - 2,pts[i].y-2), cvPoint(pts[i].x+2,pts[i].y+2),CV_RGB(0,255,0));
        cvLine (img, cvPoint (pts[i].x + 2, pts[i].y - 2), cvPoint (pts[i].x - 2, pts[i].y + 2), CV_RGB (0,255, 0));
    }

}

cvNamedWindow("SVM",CV_WINDOW_AUTOSIZE);
cvShowImage("SVM",img);
cvWaitKey(0);

float *data1 = new float[n*2];
int *res1 = new int[n];
for(i=0; i<n; i++)
{
   data1[i*2] = space[i*2];
   data1[i*2+1] =space[i*2+1];
   res1[i] = res[i];
}

/* for (i=0; i<s; i++)
{
data[i 2] = float(pts[i].x) /size ;
data[i*2 + 1] = float(pts[i].y)/size;
}/

cvInitMatHeader(&data_mat, s , 2 ,CV_32FC1, data1);
cvInitMatHeader(&res_mat, s , 1,CV_32SC1 , res1);

criteria = cvTermCriteria(CV_TERMCRIT_EPS, 1000, FLT_EPSILON);

//参数设置ONE_CLASS
param = CvSVMParams(CvSVM::ONE_CLASS, CvSVM::RBF, 10.0 , 8.0 , 1.0, 10.0, 0.5, 0.1,NULL,criteria);
//这个地方有错，不知道是参数问题 还是用法问题?
//对样本进行训练
svm.train(&data_mat,&res_mat,NULL,NULL,param);

svm_num  = svm.get_support_vector_count();
for (i=0; i<svm_num; i++)
{
    support = svm.get_support_vector(i);
    cvCircle (img, cvPoint ((int) (support[0] * size), (int) (support[1] * size)), 5, CV_RGB (200, 200, 200));
}
cvNamedWindow ("SVM", CV_WINDOW_AUTOSIZE);
cvShowImage ("SVM", img);
cvWaitKey (0);
return 1;

}

opencv不是开源的么，你把源代码搞出来看看
或者参考一下啊这个
