Detailed Description

Maximally stable extremal region extractor. :

The class encapsulates all the parameters of the MSER extraction algorithm (see http://en.wikipedia.org/wiki/Maximally_stable_extremal_regions). Also see http://code.opencv.org/projects/opencv/wiki/MSER for useful comments and parameters description.

Note

(Python) A complete example showing the use of the MSER detector can be found at opencv_source_code/samples/python2/mser.py
