Constructor & Destructor Documentation

ClassLabelChangeFilter::ClassLabelChangeFilter ( )

Default Constructor.

Definition at line 28 of file ClassLabelChangeFilter.cpp.

ClassLabelChangeFilter::ClassLabelChangeFilter ( const ClassLabelChangeFilter & rhs )

Copy Constructor.

Copies the values from the rhs ClassLabelChangeFilter to this instance of the ClassLabelChangeFilter.

Parameters

rhs	the rhs from which the values will be copied to this this instance of the ClassLabelChangeFilter

Definition at line 40 of file ClassLabelChangeFilter.cpp.

ClassLabelChangeFilter::~ClassLabelChangeFilter ( )

virtual

Default Destructor

Definition at line 58 of file ClassLabelChangeFilter.cpp.

Member Function Documentation

bool ClassLabelChangeFilter::deepCopyFrom ( const PostProcessing * postProcessing )

virtual

Sets the PostProcessing deepCopyFrom function, overwriting the base PostProcessing function. This function is used to deep copy the values from the input pointer to this instance of the PostProcessing module. This function is called by the GestureRecognitionPipeline when the user adds a new PostProcessing module to the pipeline.

Parameters

postProcessing a pointer to another instance of a ClassLabelChangeFilter, the values of that instance will be cloned to this instance

Returns: true if the deep copy was successful, false otherwise

Reimplemented from PostProcessing.

Definition at line 75 of file ClassLabelChangeFilter.cpp.

UINT ClassLabelChangeFilter::filter ( UINT predictedClassLabel )

This is the main filter function which filters the input predictedClassLabel.

Parameters

predictedClassLabel the predictedClassLabel which should be filtered return returns the filtered class label

Definition at line 130 of file ClassLabelChangeFilter.cpp.

bool ClassLabelChangeFilter::getChange ( )

Get if the class label just changed.

Returns: returns true if the class label just changed, false otherwise

Definition at line 228 of file ClassLabelChangeFilter.cpp.

UINT ClassLabelChangeFilter::getFilteredClassLabel ( )

inline

Get the most recently filtered class label value.

Returns: returns the filtered class label

Definition at line 154 of file ClassLabelChangeFilter.h.

bool ClassLabelChangeFilter::init ( )

This function initializes the ClassLabelChangeFilter.

Returns: returns true if the ClassLabelChangeFilter was initialized, false otherwise

Definition at line 119 of file ClassLabelChangeFilter.cpp.

bool ClassLabelChangeFilter::loadModelFromFile ( std::string filename )

virtual

This loads the post processing settings from a file. This overrides the loadSettingsFromFile function in the PostProcessing base class.

Parameters

filename the name of the file to load the settings from

Returns: returns true if the settings were loaded successfully, false otherwise

Reimplemented from PostProcessing.

Definition at line 177 of file ClassLabelChangeFilter.cpp.

bool ClassLabelChangeFilter::loadModelFromFile ( std::fstream & file )

virtual

This loads the post processing settings from a file. This overrides the loadSettingsFromFile function in the PostProcessing base class.

Parameters

filename the name of the file to load the settings from

Returns: returns true if the settings were loaded successfully, false otherwise

Reimplemented from PostProcessing.

Definition at line 192 of file ClassLabelChangeFilter.cpp.

ClassLabelChangeFilter & ClassLabelChangeFilter::operator= ( const ClassLabelChangeFilter & rhs )

Assigns the equals operator setting how the values from the rhs instance will be copied to this instance.

Parameters

rhs	the rhs instance from which the values will be copied to this this instance of the ClassLabelChangeFilter

Returns: returns a reference to this instance of the ClassLabelChangeFilter

Definition at line 62 of file ClassLabelChangeFilter.cpp.

bool ClassLabelChangeFilter::process ( const VectorDouble & inputVector )

virtual

Sets the PostProcessing process function, overwriting the base PostProcessing function. This function is called by the GestureRecognitionPipeline when any new input data needs to be processed (during the prediction phase for example). This function calls the ClassLabelChangeFilter's filter(...) function.

Parameters

inputVector the inputVector that should be processed. This should be a 1-dimensional vector containing a predicted class label

Returns: true if the data was processed, false otherwise

Reimplemented from PostProcessing.

Definition at line 94 of file ClassLabelChangeFilter.cpp.

bool ClassLabelChangeFilter::reset ( )

virtual

Sets the PostProcessing reset function, overwriting the base PostProcessing function. This function is called by the GestureRecognitionPipeline when the pipelines main reset() function is called. This function resets the ClassLabelChangeFilter by re-initiliazing the instance.

Returns: true if the ClassLabelChangeFilter was reset, false otherwise

Reimplemented from PostProcessing.

Definition at line 111 of file ClassLabelChangeFilter.cpp.

bool ClassLabelChangeFilter::saveModelToFile ( std::string filename ) const

virtual

This saves the post processing settings to a file. This overrides the saveSettingsToFile function in the PostProcessing base class.

Parameters

filename the name of the file to save the settings to

Returns: returns true if the settings were saved successfully, false otherwise

Reimplemented from PostProcessing.

Definition at line 143 of file ClassLabelChangeFilter.cpp.

bool ClassLabelChangeFilter::saveModelToFile ( std::fstream & file ) const

virtual

This saves the post processing settings to a file. This overrides the saveSettingsToFile function in the PostProcessing base class.

Parameters

filename the name of the file to save the settings to

Returns: returns true if the settings were saved successfully, false otherwise

Reimplemented from PostProcessing.

Definition at line 163 of file ClassLabelChangeFilter.cpp.
