Public Methods

Method	Description
Create ( ) : EM	Creates empty EM model.
GetCovs ( ) : OpenCvSharp.Mat[]	Returns covariation matrices. Returns vector of covariation matrices. Number of matrices is the number of gaussian mixtures, each matrix is a square floating-point matrix NxN, where N is the space dimensionality.
GetMeans ( ) : OpenCvSharp.Mat	Returns the cluster centers (means of the Gaussian mixture). Returns matrix with the number of rows equal to the number of mixtures and number of columns equal to the space dimensionality.
GetWeights ( ) : OpenCvSharp.Mat	Returns weights of the mixtures. Returns vector with the number of elements equal to the number of mixtures.
Predict2 ( InputArray sample, OutputArray probs = null ) : Vec2d	Predicts the response for sample
TrainE ( InputArray samples, InputArray means0, InputArray covs0 = null, InputArray weights0 = null, OutputArray logLikelihoods = null, OutputArray labels = null, OutputArray probs = null ) : bool	Estimates Gaussian mixture parameters from the sample set
TrainM ( InputArray samples, InputArray probs0, OutputArray logLikelihoods = null, OutputArray labels = null, OutputArray probs = null ) : bool	Estimates Gaussian mixture parameters from the sample set

Protected Methods

Method	Description
Dispose ( bool disposing ) : void	Clean up any resources being used.
EM ( IntPtr p ) : System	Creates instance by raw pointer cv::ml::EM*

Method Details

Create() public static method

Creates empty EM model.

public static Create ( ) : EM
return	EM

Dispose() protected method

Clean up any resources being used.

protected Dispose ( bool disposing ) : void
disposing	bool	/// If disposing equals true, the method has been called directly or indirectly by a user's code. Managed and unmanaged resources can be disposed. /// If false, the method has been called by the runtime from inside the finalizer and you should not reference other objects. Only unmanaged resources can be disposed. ///
return	void
