Methods

	Name	Description
	ComputeQuadraticFormDistance	Computes Signature Quadratic Form Distance of two signatures.
	ComputeQuadraticFormDistances	Computes Signature Quadratic Form Distance between the reference signature and each of the other image signatures.
	Dispose	The dispose function that implements IDisposable interface (Inherited from DisposableObject.)
	DisposeObject	Release the unmanaged memory associated with this PCTSignaturesSQFD object (Overrides DisposableObjectDisposeObject.)
	Equals	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Finalize	Destructor (Inherited from DisposableObject.)
	GetHashCode	Serves as a hash function for a particular type. (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.)
	ReleaseManagedResources	Release the managed resources. This function will be called during the disposal of the current object. override ride this function if you need to call the Dispose() function on any managed IDisposable object created by the current object (Inherited from DisposableObject.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Fields

	Name	Description
	_ptr	A pointer to the unmanaged object (Inherited from UnmanagedObject.)
	_sharedPtr	A pointer to the shared pointer to the unmanaged object (Inherited from SharedPtrObject.)
