Performs Principal Component Analysis of the supplied dataset.

Namespace: Emgu.CV
Assembly: Emgu.CV.World (in Emgu.CV.World.dll) Version: 4.1.1.3497 (4.1.1.3497)

Syntax

public static void PCACompute(
	IInputArray data,
	IInputOutputArray mean,
	IOutputArray eigenvectors,
	double retainedVariance
)

Public Shared Sub PCACompute ( 
	data As IInputArray,
	mean As IInputOutputArray,
	eigenvectors As IOutputArray,
	retainedVariance As Double
)

public:
static void PCACompute(
	IInputArray^ data, 
	IInputOutputArray^ mean, 
	IOutputArray^ eigenvectors, 
	double retainedVariance
)

static member PCACompute : 
        data : IInputArray * 
        mean : IInputOutputArray * 
        eigenvectors : IOutputArray * 
        retainedVariance : float -> unit

Parameters

data: Type: Emgu.CVIInputArray
Input samples stored as the matrix rows or as the matrix columns.
mean: Type: Emgu.CVIInputOutputArray
Optional mean value; if the matrix is empty, the mean is computed from the data.
eigenvectors: Type: Emgu.CVIOutputArray
The eigenvectors.
retainedVariance: Type: SystemDouble
Percentage of variance that PCA should retain. Using this parameter will let the PCA decided how many components to retain but it will always keep at least 2.
