    Sample Code for Image Masking in OpenCV:

    Typedef struct CvHistogram


    int          type;

    CvArr*   bins;

    float     thresh[CV_MAX_DTM] [2]; /* for uniform histograms*/

    float** thresh2; /* for non-uniform histograms */

    CvMatND mat; /* embedded matrix header for array histograms */



    IplImage* mask;

    mask = cvCreateImage( cvGetSize (hsv), IPL_DEPTH_8U, 1);

    cvZero (mask);

    cvRectangle (mask, cvPoint (10,10), cvPoint (100,100), cvScalarAll (255), CV_FILLED);

    cvCalcHist (planes, hist, 0, mask);     //Compute Histogram OpenCV Projects
