I tried this code.... But it says height and width are uninitialized...

What Modification in the code by Microsoft Kinect D2D sample has to be made to connect it with openCV?

I got this code from a site.....

cvSetData(img,(BYTE*) pBuffer, img->widthStep);
Mat &m = Mat(img);
Mat &hsv = Mat();
vector<Mat> mv = vector<Mat>(3,Mat(cvSize(640,480),CV_8UC1));
cvtColor(m,hsv,CV_BGR2HSV);
cvtColor(hsv,m,CV_HSV2BGR);//*/
IplImage iplimg(m);
cvNamedWindow("rgb",1);
cvShowImage("rgb",&iplimg);

But here it is not told how to initialize the "img".... Help!!
