The GroupMatching type exposes the following members.

Constructors
  NameDescription
Public methodGroupMatching
Creates a new GroupMatching object.

Properties
  NameDescription
Public propertyClasses (Inherited from GroupMatchingT.)
Public propertyMinimumNeighbors
Gets or sets the minimum number of neighbors necessary to keep a detection. If a rectangle has less neighbors than this number, it will be discarded as a false positive.
(Inherited from GroupMatchingT.)
Protected propertyThreshold
Gets the minimum distance threshold to consider two rectangles as neighbors. Default is 0.2.

Methods
  NameDescription
Protected methodAverage
Averages rectangles which belongs to the same class (have the same class label)
(Overrides GroupMatchingTAverage(Int32, T, Int32).)
Public methodEquals
Determines whether the specified object is equal to the current object.
(Inherited from Object.)
Protected methodFinalize
Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.
(Inherited from Object.)
Public methodGetHashCode
Serves as the default hash function.
(Inherited from Object.)
Public methodGetType
Gets the Type of the current instance.
(Inherited from Object.)
Public methodGroup
Groups possibly near rectangles into a smaller set of distinct and averaged rectangles.
(Inherited from GroupMatchingT.)
Protected methodMemberwiseClone
Creates a shallow copy of the current Object.
(Inherited from Object.)
Protected methodNear
Checks if two rectangles are near.
(Overrides GroupMatchingTNear(T, T).)
Public methodToString
Returns a string that represents the current object.
(Inherited from Object.)

Extension Methods
  NameDescription
Public Extension MethodHasMethod
Checks whether an object implements a method with the given name.
(Defined by ExtensionMethods.)
Public Extension MethodToTOverloaded.
Converts an object into another type, irrespective of whether the conversion can be done at compile time or not. This can be used to convert generic types to numeric types during runtime.
(Defined by ExtensionMethods.)
Public Extension MethodToTOverloaded.
Converts an object into another type, irrespective of whether the conversion can be done at compile time or not. This can be used to convert generic types to numeric types during runtime.
(Defined by Matrix.)

Remarks
This class can be seen as a post-processing filter. Its goal is to group near or contained regions together in order to produce more robust and smooth estimates of the detected regions.
