public class CvStatModel
extends Object

Base class for statistical models in ML.

class CvStatModel

// C++ code:

public:

/ * CvStatModel(); * /

/ * CvStatModel(const Mat& train_data...); * /

virtual ~CvStatModel();

virtual void clear()=0;

/ * virtual bool train(const Mat& train_data, [int tflag,]..., const

Mat& responses,...,

[const Mat& var_idx,]..., [const Mat& sample_idx,]...

[const Mat& var_type,]..., [const Mat& missing_mask,]

...)=0;

• /

/ * virtual float predict(const Mat& sample...) const=0; * /

virtual void save(const char* filename, const char* name=0)=0;

virtual void load(const char* filename, const char* name=0)=0;

virtual void write(CvFileStorage* storage, const char* name)=0;

virtual void read(CvFileStorage* storage, CvFileNode* node)=0;

};

In this declaration, some methods are commented off. These are methods for which there is no unified API (with the exception of the default constructor). However, there are many similarities in the syntax and semantics that are briefly described below in this section, as if they are part of the base class.

Method Detail

load

public void load(String filename,
        String name)

Loads the model from a file.

The method load loads the complete model state with the specified name (or default model-dependent name) from the specified XML or YAML file. The previous model state is cleared by "CvStatModel.clear".

Parameters:

filename - a filename

name - a name

See Also:

org.opencv.ml.CvStatModel.load

load

public void load(String filename)

Loads the model from a file.

The method load loads the complete model state with the specified name (or default model-dependent name) from the specified XML or YAML file. The previous model state is cleared by "CvStatModel.clear".

Parameters:

filename - a filename

See Also:

org.opencv.ml.CvStatModel.load

save

public void save(String filename,
        String name)

Saves the model to a file.

The method save saves the complete model state to the specified XML or YAML file with the specified name or default name (which depends on a particular class). *Data persistence* functionality from CxCore is used.

Parameters:

filename - a filename

name - a name

See Also:

org.opencv.ml.CvStatModel.save

save

public void save(String filename)

Saves the model to a file.

The method save saves the complete model state to the specified XML or YAML file with the specified name or default name (which depends on a particular class). *Data persistence* functionality from CxCore is used.

Parameters:

filename - a filename

finalize

protected void finalize()
                 throws Throwable

Overrides:

finalize in class Object

Throws:

Throwable
