Cv2PCAComputeVar Method (InputArray, InputOutputArray, OutputArray, Double)

PCA of the supplied dataset.

Namespace: OpenCvSharp
Assembly: OpenCvSharp (in OpenCvSharp.dll) Version: 1.0.0

Syntax

public static void PCAComputeVar(
	InputArray data,
	InputOutputArray mean,
	OutputArray eigenvectors,
	double retainedVariance
)

Public Shared Sub PCAComputeVar ( 
	data As InputArray,
	mean As InputOutputArray,
	eigenvectors As OutputArray,
	retainedVariance As Double
)

public:
static void PCAComputeVar(
	InputArray^ data, 
	InputOutputArray^ mean, 
	OutputArray^ eigenvectors, 
	double retainedVariance
)

static member PCAComputeVar : 
        data : InputArray * 
        mean : InputOutputArray * 
        eigenvectors : OutputArray * 
        retainedVariance : float -> unit

Parameters

data: Type: OpenCvSharpInputArray
input samples stored as the matrix rows or as the matrix columns.
mean: Type: OpenCvSharpInputOutputArray
optional mean value; if the matrix is empty (noArray()), the mean is computed from the data.
eigenvectors: Type: OpenCvSharpOutputArray
eigenvectors of the covariation matrix
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.
