Description

I've updated old mser_sample.cpp to work with new 3.0 interface a follows:

vector<vector<Point> > contours;
vector<Rect> boxes;
Ptr<MSER> mser = MSER::create();

mser->detectRegions(yuv, contours, boxes);

where boxes are the optional masks, which marks the areas where MSERs are searched for (according to documentation):
[[http://docs.opencv.org/trunk/modules/features2d/doc/feature_detection_and_description.html]]

Code works as expected, but when I add a mask to limit inspected area:
boxes.push_back ( Rect(100,100,400,300));
it has no influence on result nor algorithm computation time. MSERs are found on the whole image as without any mask.
