using namespace std;
using namespace cv;
int main()
{ // cvZero(mat);// mat[0][0]=1;
    IplImage* img=cvLoadImage("image1.jpg");
    IplImage* img1=cvLoadImage("image1.jpg");
    //cout<<img->nChannels;
    // CvArr* mat=cvCreateMat(img->height,img->width,CV_32FC3);
    // cvZero(mat);cvNamedWindow("source");cvNamedWindow("dest");
    cvCanny(img,img1,10,50,3);
    cvShowImage("source",img);
    cvShowImage("dest",img1);
    cvWaitKey();
    return 0;
