Hello leo,
You can use several different ways to create mask for image.
If you create images your self you can use alpha-channel as a mask. You need to save image in *.png format, and then load it with flags =-1 in imread. Then split it with cv::split function and path alpha channel as a mask.
If you cannot use alpha channel you can create mask using threshold (http://docs.opencv.org/trunk/modules/imgproc/doc/miscellaneous_transformations.html?highlight=threshold#cv.Threshold)
