conversion of cvMat to IplImage

Question

I have two programs, one which accepts an Image as a matrix and does the processing like tracking objects using contour detection.The second program takes image as an array(IplImage) and counting no. of objects.But I want to merge these programs to count as well as track these objects.How can I merge them ?

In the following code left is CvMat, left1 is IplImage. In this way you can manually convert cvmat to IplImage.

for (int y=0;y<height1;y++)
          {
                   uchar* leftdata=(uchar*)(left->data.ptr+y*left->step);
                   uchar* left1data=(uchar* )(left->imageData+y*left1step);
               for (int x=0;x<width1;x++)
                   left1data[x]=leftdata[x];
          }
