| MCvERStat Structure |
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.

SyntaxThe MCvERStat type exposes the following members.
Methods| Name | Description | |
|---|---|---|
 | Equals | Indicates whether this instance and a specified object are equal. (Inherited from ValueType.) |
 | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
| GetCenter |
Get the center of the region
|
| GetHashCode | Returns the hash code for this instance. (Inherited from ValueType.) |
| GetType | Gets the type of the current instance. (Inherited from Object.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| ToString | Returns the fully qualified type name of this instance. (Inherited from ValueType.) |
