Syntax

public class PCA : DisposableCvObject

Public Class PCA

The PCA type exposes the following members.

Constructors

	Name	Description
	PCA	Initializes a new instance of the PCA class
	PCA(InputArray, InputArray, PCAFlag, Double)	Initializes a new instance of the PCA class
	PCA(InputArray, InputArray, PCAFlag, Int32)	Initializes a new instance of the PCA class

Properties

	Name	Description
	AllocatedMemory	Gets or sets a memory address allocated by AllocMemory. (Inherited from DisposableObject.)
	AllocatedMemorySize	Gets or sets the byte length of the allocated memory (Inherited from DisposableObject.)
	CvPtr	Native pointer of OpenCV structure (Inherited from DisposableCvObject.)
	Eigenvalues	eigenvalues of the covariation matrix
	Eigenvectors	eigenvalues of the covariation matrix
	IsDisposed	Gets a value indicating whether this instance has been disposed. (Inherited from DisposableObject.)
	IsEnabledDispose	Gets or sets a value indicating whether you permit disposing this instance. (Inherited from DisposableObject.)
	Mean	mean value subtracted before the projection and added after the back projection

Methods

	Name	Description
	AllocGCHandle	Pins the object to be allocated by cvSetData. (Inherited from DisposableObject.)
	AllocMemory	Allocates the specified size of memory. (Inherited from DisposableObject.)
	BackProject(InputArray)	reconstructs the original vector from the projection
	BackProject(InputArray, OutputArray)	reconstructs the original vector from the projection
	Compute	operator that performs PCA. The previously stored data, if any, is released
	ComputeVar	operator that performs PCA. The previously stored data, if any, is released
	Dispose	Releases the resources (Inherited from DisposableObject.)
	Dispose(Boolean)	Releases the unmanaged resources used by the PCA and optionally releases the managed resources (Overrides DisposableCvObjectDispose(Boolean).)
	Equals	(Inherited from Object.)
	Finalize	Destructor (Inherited from DisposableObject.)
	GetHashCode	(Inherited from Object.)
	GetType	(Inherited from Object.)
	MemberwiseClone	(Inherited from Object.)
	NotifyMemoryPressure	Notifies the allocated size of memory. (Inherited from DisposableObject.)
	Project(InputArray)	projects vector from the original space to the principal components subspace
	Project(InputArray, OutputArray)	projects vector from the original space to the principal components subspace
	ThrowIfDisposed	If this object is disposed, then ObjectDisposedException is thrown. (Inherited from DisposableObject.)
	ToString	(Inherited from Object.)

Fields

	Name	Description
	dataHandle	Gets or sets a handle which allocates using cvSetData. (Inherited from DisposableObject.)
	ptr	Data pointer (Inherited from DisposableCvObject.)
