Opencv中将CvMat转为IplImage

  Opencv中将CvMat转为IplImage，并在内存获得起头指针，而不用cvSaveImage(),贴上代码

IplImage * imgg = NULL;
    imgg = cvCreateImage(cvSize(modelF[0].Matrix->cols,modelF[0].Matrix->rows),IPL_DEPTH_8U,1);
    
    float ve;
    for(int n = 0; n < modelF[0].Matrix->rows; n++){
        for(int m = 0; m < modelF[0].Matrix->cols; m++){
            ve = CV_MAT_ELEM(*(modelF[0].Matrix),float,n,m);
            CV_IMAGE_ELEM(imgg,uchar,n,m) = (uchar)cvRound(ve);
        }
    }

　cvNamedWindow("imgg",CV_WINDOW_AUTOSIZE);
　cvShowImage("imgg",imgg);
　cvWaitKey(0);

 注意这里的cvSize类的用法，cvSize(int width,int height) 是先输入图像矩阵的列，再输入行
