Detailed Description

Class to extract local extrema in the image.

The extrema can either be accessed as a List of points in the image where they occur or as an Image with the extrema marked with single pixel dots of intensity value 255. The image registered with this class stays un-modified during and after the extraction.

Public Member Functions
	ImExtrema (void)
	Default constructor.
	ImExtrema (const iptk::Image &im)
	Image registering constructor.
	ImExtrema (const ImExtrema &ip)
	Copy constructor Though this constructor does not look like a reference copier, the image data is shared between the passed object(i.e the parameter to the copy constructor) and the new object.
virtual	~ImExtrema ()
	Do nothing destructor.
virtual void	process (void)
	The function which does the actual extraction of the extrema.
iptk::Image	getMaxImage (void)
	Returns the spotted maxima image.
iptk::Image	getMinImage (void)
	Returns the spotted minima image.
tutk::List< gutk::Point >	getExtrema (void)
	Returns a List of extremum pixels.
tutk::List< gutk::Point >	getMaxima (void)
	Returns a List of maximum pixels.
tutk::List< gutk::Point >	getMinima (void)
	Returns a List of minimum pixels.

Constructor & Destructor Documentation

iptk::ImExtrema::ImExtrema (  void   )

Default constructor. An object created using the default constructor should set the image by using the setImage member function.

iptk::ImExtrema::ImExtrema (  const iptk::Image &  im  )

Image registering constructor. The image is autmatically registered at the construction stage.

virtual iptk::ImExtrema::~ImExtrema (   )  [virtual]

Do nothing destructor. Destructor does nothing at all as the default destructor would have been sufficient.

Member Function Documentation

tutk::List< gutk::Point > iptk::ImExtrema::getExtrema (  void   )

Returns a List of extremum pixels. For a valid result, this function should be called only after a call to the process member function.

tutk::List< gutk::Point > iptk::ImExtrema::getMaxima (  void   )

Returns a List of maximum pixels. For a valid result, this function should be called only after a call to the process member function.

iptk::Image iptk::ImExtrema::getMaxImage (  void   )

Returns the spotted maxima image. For a valid result, this function should be called only after a call to the process member function.

tutk::List< gutk::Point > iptk::ImExtrema::getMinima (  void   )

Returns a List of minimum pixels. For a valid result, this function should be called only after a call to the process member function.

iptk::Image iptk::ImExtrema::getMinImage (  void   )

Returns the spotted minima image. For a valid result, this function should be called only after a call to the process member function.

virtual void iptk::ImExtrema::process (  void   )  [virtual]

The function which does the actual extraction of the extrema. The extrema are extracted only at the call to this function. Implements iptk::NeighbourhoodStatisticsFilter.
