# How to used MSER in OpenCV2.4.2 to detect regions?

We know that MSER(Maximally stable extremal region)was to detect affine regions between stereo images(http://en.wikipedia.org/wiki/Maximally*stable*extremal_regions).I just could get points(x pixel coordinate and y pixel coordinate) using MserFeatureDetector,However，I extremmely like to get region parameters besides points,such format: u(pixel coordinate x ),v(pixel coordinate y),a,b,c(a,b and c are affine region parameters),ellipse would be drawn by a,b and c.Is any friend would help me to solve the problem?
