Detailed Description

Maximal Stable Extremal Regions class.

The class implements MSER algorithm introduced by J. Matas. Unlike SIFT, SURF and many other detectors in OpenCV, this is salient region detector, not the salient point detector.

It returns the regions, each of those is encoded as a contour.
