Detailed Description

Gabor kernel used for various computer vision tasks.

This class encapsulates a complex Gabor kernel used for various computer vision tasks such as texture segmentation, motion analysis, and object recognition. It is essentially a complex sinusoid enveloped within a gaussian. See the discussion in

Andreas Klein, Forester Lee, and Amir A. Amini, "Quantitative Coronary Angiography with Deformable Spline Models", IEEE-TMI 16(5):468-482, October 1997.

for a basic discussion including additional references.

This implementation was contributed as a paper to the Insight Journal http://hdl.handle.net/1926/500

Member Function Documentation

unsigned long itk::Object::AddObserver ( const EventObject event,
Command  
) const [inherited]

This is a global flag that controls whether any debug, warning or error messages are displayed.

unsigned long itk::Object::AddObserver ( const EventObject event,
Command  
) [inherited]

Allow people to add/remove/invoke observers (callbacks) to any ITK object. This is an implementation of the subject/observer design pattern. An observer is added by specifying an event to respond to and an itk::Command to execute. It returns an unsigned long tag which can be used later to remove the event or retrieve the command. The memory for the Command becomes the responsibility of this object, so don't pass the same instance of a command to two different objects

static void itk::LightObject::BreakOnError (  )  [static, inherited]

This method is called when itkExceptionMacro executes. It allows the debugger to break on error.

virtual void itk::GaborKernelFunction::CalculateImaginaryPartOff (  )  [virtual]
virtual void itk::GaborKernelFunction::CalculateImaginaryPartOn (  )  [virtual]
virtual LightObject::Pointer itk::Object::CreateAnother (  )  const [virtual, inherited]
virtual void itk::Object::DebugOff (  )  const [virtual, inherited]

Turn debugging output off.

virtual void itk::Object::DebugOn (  )  const [virtual, inherited]

Turn debugging output on.

virtual void itk::LightObject::Delete (  )  [virtual, inherited]

Delete an itk object. This method should always be used to delete an object when the new operator was used to create it. Using the C delete method will not work with reference counting.

double itk::GaborKernelFunction::Evaluate ( const double &  u  )  const [inline, virtual]

Evaluate the function.

Implements itk::KernelFunction.

Definition at line 64 of file itkGaborKernelFunction.h.

virtual bool itk::GaborKernelFunction::GetCalculateImaginaryPart (  )  const [virtual]
Command* itk::Object::GetCommand ( unsigned long  tag  )  [inherited]

Get the command associated with the given tag. NOTE: This returns a pointer to a Command, but it is safe to asign this to a Command::Pointer. Since Command inherits from LightObject, at this point in the code, only a pointer or a reference to the Command can be used.

bool itk::Object::GetDebug (  )  const [inherited]

Get the value of the debug flag.

virtual double itk::GaborKernelFunction::GetFrequency (  )  const [virtual]
static bool itk::Object::GetGlobalWarningDisplay (  )  [static, inherited]

This is a global flag that controls whether any debug, warning or error messages are displayed.

const MetaDataDictionary& itk::Object::GetMetaDataDictionary ( void   )  const [inherited]
Returns:
A constant reference to this objects MetaDataDictionary.
MetaDataDictionary& itk::Object::GetMetaDataDictionary ( void   )  [inherited]
Returns:
A reference to this objects MetaDataDictionary.
Warning:
This reference may be changed.
virtual unsigned long itk::Object::GetMTime (  )  const [virtual, inherited]

Return this objects modified time.
