OpenCV 3.0.0 MSER Binary Mask

Question

I am trying to use MSER algorithm in OpenCV 3.0.0 beta to extract text regions from an image. At the end I need a binary mask with the detected MSER regions, but the algorit

Answer 1

I found the solution! Just loop over all the points and draw them!

void mserExtractor (const Mat& image, Mat& mserOutMask){
    Ptr<MSER> mserExtractor  = MSER::create();

    vector<vector<cv::Point>> mserContours;
    vector<KeyPoint> mserKeypoint;
    vector<cv::Rect> mserBbox;
    mserExtractor->detectRegions(image, mserContours,  mserBbox);

    for (vector<cv::Point> v : mserContours){
        for (cv::Point p : v){
            mserOutMask.at<uchar>(p.y, p.x) = 255;
        }
    }
}
