Constructor & Destructor Documentation

ClassLabelTimeoutFilter::ClassLabelTimeoutFilter ( const unsigned long  timeoutDuration = 1000,
const UINT  filterMode = ALL_CLASS_LABELS 
)

Default Constructor. Sets the timeoutDuration and filterMode parameters.

The timeoutDuration sets how long (in milliseconds) the Class Label Timeout Filter will debounce valid predicted class labels for, after it has viewed the first valid predicted class label which triggers the debounce mode to be activated. A valid predicted class label is simply a predicted class label that is not the default null rejection class label (i.e. a label with the class value of 0). The filterMode parameter sets how the Class Label Timeout Filter reacts to different predicted class labels (different from the predicted class label that triggers the debounce mode to be activated). There are two options for the filterMode: ALL_CLASS_LABELS or INDEPENDENT_CLASS_LABELS. In the ALL_CLASS_LABELS filterMode, after the debounce mode has been activated, all class labels will be ignored until the current timeoutDuration period has elapsed, regardless of which class actually triggered the timeout. Alternatively, in the INDEPENDENT_CLASS_LABELS mode, the debounce mode will be reset if a different predicted class label is detected that is different from the predicted class label that initially triggered the debounce mode to be activated. For instance, if the debounce mode was activated with the class label of 1, and then class 2 was input into the class label filter, then the debounce mode would be reset to class 2, even if the timeoutDuration for class 1 had not expired.

Parameters
timeoutDurationsets the timeoutDuration value (in milliseconds). Default value timeoutDuration=1000
filterModesets the filterMode parameter. Default value filterMode=ALL_CLASS_LABELS

Member Function Documentation

bool ClassLabelTimeoutFilter::deepCopyFrom ( const PostProcessing postProcessing)
overridevirtual

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
postProcessinga pointer to another instance of a ClassLabelTimeoutFilter, 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 ClassLabelTimeoutFilter.cpp.

UINT ClassLabelTimeoutFilter::filter ( const UINT  predictedClassLabel)

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

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

Definition at line 139 of file ClassLabelTimeoutFilter.cpp.

UINT ClassLabelTimeoutFilter::getFilteredClassLabel ( ) const
inline

Get the most recently filtered class label value.

Returns
returns the filtered class label

bool ClassLabelTimeoutFilter::init ( const unsigned long  timeoutDuration,
const UINT  filterMode = ALL_CLASS_LABELS 
)

This function initializes the ClassLabelTimeoutFilter.

Parameters
timeoutDurationsets the timeoutDuration value (in milliseconds)
filterModesets the filterMode parameter
Returns
returns true if the ClassLabelTimeoutFilter was initialized, false otherwise

Definition at line 122 of file ClassLabelTimeoutFilter.cpp.

bool ClassLabelTimeoutFilter::isTimeoutActive ( )

Get if the filter is currently ignorning new inputs because the timeout is active.

Returns
returns true if the timeout mode is active, false otherwise

Definition at line 217 of file ClassLabelTimeoutFilter.cpp.

bool ClassLabelTimeoutFilter::load ( std::fstream &  file)
overridevirtual

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

Parameters
filenamethe name of the file to load the settings from
Returns
returns true if the settings were loaded successfully, false otherwise

Reimplemented from MLBase.

Definition at line 244 of file ClassLabelTimeoutFilter.cpp.

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

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

Parameters
rhsthe rhs instance from which the values will be copied to this this instance of the ClassLabelTimeoutFilter
Returns
returns a reference to this instance of the ClassLabelTimeoutFilter

Definition at line 60 of file ClassLabelTimeoutFilter.cpp.

bool ClassLabelTimeoutFilter::process ( const VectorDouble inputVector)
overridevirtual

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 ClassLabelTimeoutFilter's filter(...) function.

Parameters
inputVectorthe 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 95 of file ClassLabelTimeoutFilter.cpp.

bool ClassLabelTimeoutFilter::reset ( )
overridevirtual

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 ClassLabelTimeoutFilter by re-initiliazing the instance.

Returns
true if the ClassLabelTimeoutFilter was reset, false otherwise

Reimplemented from MLBase.

Definition at line 114 of file ClassLabelTimeoutFilter.cpp.

bool ClassLabelTimeoutFilter::save ( std::fstream &  file) const
overridevirtual

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

Parameters
filenamethe name of the file to save the settings to
Returns
returns true if the settings were saved successfully, false otherwise

Reimplemented from MLBase.

Definition at line 228 of file ClassLabelTimeoutFilter.cpp.

bool ClassLabelTimeoutFilter::setFilterMode ( const UINT  filterMode)

Sets the filterMode parameter, must be a value greater than 0.

The filterMode parameter sets how the Class Label Timeout Filter reacts to different predicted class labels (different from the predicted class label that triggers the debounce mode to be activated). There are two options for the filterMode: ALL_CLASS_LABELS or INDEPENDENT_CLASS_LABELS. In the ALL_CLASS_LABELS filterMode, after the debounce mode has been activated, all class labels will be ignored until the current timeoutDuration period has elapsed, regardless of which class actually triggered the timeout. Alternatively, in the INDEPENDENT_CLASS_LABELS mode, the debounce mode will be reset if a different predicted class label is detected that is different from the predicted class label that initially triggered the debounce mode to be activated.

For instance, if the debounce mode was activated with the class label of 1, and then class 2 was input into the class label filter, then the debounce mode would be reset to class 2, even if the timeoutDuration for class 1 had not expired. If the Class Label Filter has been initialized then the module will be reset.

Parameters
filterModethe new filterMode parameter
Returns
returns true if the filterMode parameter was updated, false otherwise

Definition at line 303 of file ClassLabelTimeoutFilter.cpp.

bool ClassLabelTimeoutFilter::setTimeoutDuration ( const unsigned long  timeoutDuration)

Sets the timeoutDuration parameter, must be a value greater than 0.

The timeoutDuration sets how long (in milliseconds) the Class Label Timeout Filter will debounce valid predicted class labels for, after it has viewed the first valid predicted class label which triggers the debounce mode to be activated. A valid predicted class label is simply a predicted class label that is not the default null rejection class label (i.e. a label with the class value of 0). If the Class Label Filter has been initialized then the module will be reset.

Parameters
timeoutDurationthe new timeoutDuration parameter
Returns
returns true if the timeoutDuration parameter was updated, false otherwise
