MCvERStat Structure
http://www.emgu.com
The ERStat structure represents a class-specific Extremal Region (ER). An ER is a 4-connected set of pixels with all its grey-level values smaller than the values in its outer boundary. A class-specific ER is selected (using a classifier) from all the ER’s in the component tree of the image.
