Member Function Documentation

bool MovementDetector::clear ( )
virtual

This overrides the clear function in the ML base class. It will completely clear the ML module, removing any trained model and setting all the base variables to their default values.

Returns
returns true if the module was cleared succesfully, false otherwise

Reimplemented from MLBase.

Definition at line 84 of file MovementDetector.cpp.

bool MovementDetector::loadModelFromFile ( std::fstream &  file)
virtual

This loads a trained MovementDetector model from a file. This overrides the loadModelFromFile function in the ML base class.

Parameters
filea reference to the file the MovementDetector model will be loaded from
Returns
returns true if the model was loaded successfully, false otherwise

Reimplemented from MLBase.

Definition at line 126 of file MovementDetector.cpp.

bool MovementDetector::predict_ ( VectorFloat &  inputVector)
virtual

This is the main prediction interface for all the GRT machine learning algorithms. This should be overwritten by the derived class.

Parameters
inputVectora reference to the input vector for prediction
Returns
returns true if the prediction was completed succesfully, false otherwise (the base class always returns false)

Reimplemented from MLBase.

Definition at line 29 of file MovementDetector.cpp.

bool MovementDetector::reset ( )
virtual

This overrides the reset function in the ML base class. It will reset the MovementDetector, setting the state back to the search timeout and resetting the movementIndex to zero.

Returns
returns true if the module was reset succesfully, false otherwise

Reimplemented from MLBase.

Definition at line 94 of file MovementDetector.cpp.

bool MovementDetector::saveModelToFile ( std::fstream &  file) const
virtual

This saves the trained MovementDetector model to a file. This overrides the saveModelToFile function in the ML base class.

Parameters
filea reference to the file the MovementDetector model will be saved to
Returns
returns true if the model was saved successfully, false otherwise

Reimplemented from MLBase.

Definition at line 106 of file MovementDetector.cpp.
