Methods

	Name	Description
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	ToBase64	Converts the binary descriptor to base64.
	ToBinary	Converts the binary descriptor to a string of binary values.
	ToHex	Converts the binary descriptor to string of hexadecimal values.
	ToIntPoint	Converts the feature point to a IntPoint.
	ToPoint	Converts this object into a IntPoint.
	ToPointF	Converts this object into a PointF.
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Operators

	Name	Description
	(FastRetinaKeypoint to Point)	Performs an implicit conversion from FastRetinaKeypoint to Point.

Extension Methods

	Name	Description
	HasMethod	Checks whether an object implements a method with the given name. (Defined by ExtensionMethods.)
	IsEqual	Compares two objects for equality, performing an elementwise comparison if the elements are vectors or matrices. (Defined by Matrix.)
	To(Type)	Overloaded. 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.)
	ToT	Overloaded. 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.)
