1、IplImage转Cvmat
IplImage* src = cvLoadImage（"rice.bmp",0）; CvMat* mat=cvCreateMat(src->height,src->width,CV_32SC1); cvConvert(src,mat);
或者：
Cvmat matObj;
* mat=cvGetmat(src,&matObj);2、Cvmat转IplImage
IplImage* pImg = cvCreateImage(cvGetSize(mat),8,1); cvGetImage(matI,pImg); cvSaveImage("rice1.bmp",pImg);

使用函数cvGetMat和cvGetImage，首先要创建矩阵头，和图像头，数据共享。
例：
IplImage,CvMat圖形矩陣空間
#include <cv.h> #include <highgui.h> #include <stdio.h> int main() { IplImage *Image1; IplImage *Image2; CvMat *Matrix1; CvSize Size1; Image1=cvLoadImage("footpath.jpg",1); Size1=cvGetSize(Image1); Image2=cvCreateImageHeader(Size1,IPL_DEPTH_8U,3); Matrix1=cvCreateMatHeader(Size1.height,Size1.width,CV_8UC3); cvGetMat(Image1,Matrix1); cvFlip(Matrix1,Matrix1,1); cvGetImage(Matrix1,Image2); cvNamedWindow("footpath (Flip)",1); cvShowImage("footpath (Flip)",Image2); cvWaitKey(0); cvReleaseImage(&Image1); cvReleaseImageHeader(&Image2); cvReleaseMatHeader(&Matrix1); cvDestroyWindow("footpath (Flip)"); }
