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
