PCA Constructor (InputArray, InputArray, PCAFlags, Double)

public PCA(
	InputArray data,
	InputArray mean,
	PCAFlags flags,
	double retainedVariance
)

Public Sub New ( 
	data As InputArray,
	mean As InputArray,
	flags As PCAFlags,
	retainedVariance As Double
)

public:
PCA(
	InputArray^ data, 
	InputArray^ mean, 
	PCAFlags flags, 
	double retainedVariance
)

new : 
        data : InputArray * 
        mean : InputArray * 
        flags : PCAFlags * 
        retainedVariance : float -> PCA

Parameters

data

Type: OpenCvSharpInputArray
input samples stored as matrix rows or matrix columns.

mean

Type: OpenCvSharpInputArray
optional mean value; if the matrix is empty (noArray()), the mean is computed from the data.

flags

Type: OpenCvSharpPCAFlags
operation flags; currently the parameter is only used to specify the data layout (PCA::Flags)

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.
