Detailed Description

This class provides some possibilites to visualize the given SOFM.

If the drawer is an instance of ltiDraw<T>, you have to set the background color of the image that is used to a value that is different from the drawing colors in the colormap.

virtual functor* lti::SOFM2DVisualizer::clone

(

)

const [virtual]

returns a pointer to a clone of this functor.

Implements lti::functor.

template<typename T >

bool lti::SOFM2DVisualizer::componentPlane	(	drawBase< T > &	drawer,
		const SOFM2D &	som,
		const int &	comp
	)			const [inline]

Draws one component of the given som.

(

const SOFM2DVisualizer &

other

)

copy data of "other" functor.

Parameters:

other

the functor to be copied

Returns:

a reference to this functor object

Reimplemented from lti::functor.

template<typename T >

bool lti::SOFM2DVisualizer::drawClasses	(	drawBase< T > &	drawer,
		const SOFM2D &	som,
		const dmatrix &	data,
		const ivector &	ids
	)			const [inline]

draws distribution of data colored according to ids.

Parameters:

	drawer	the drawing object
	som	the som to draw
	data	the
	ids	the ids according to the data

Returns:

true if apply successful or false otherwise.

template<typename T >

bool lti::SOFM2DVisualizer::drawHits	(	drawBase< T > &	drawer,
		const SOFM2D &	som,
		const dmatrix &	data
	)			const [inline]

Classifies the given data with the som and draws the distribution of the hits where the data points were classified in the som.

virtual const char* lti::SOFM2DVisualizer::getTypeName

(

)

const [virtual]

returns the name of this type ("SOFM2DVisualizer")

Reimplemented from lti::functor.

SOFM2DVisualizer& lti::SOFM2DVisualizer::operator=

(

const SOFM2DVisualizer &

other

)

alias for copy member

Parameters:

other

the functor to be copied

Returns:

a reference to this functor object

Reimplemented from lti::functor.

template<typename T >

bool lti::SOFM2DVisualizer::sammonsMapper	(	drawBase< T > &	drawer,
		const SOFM2D &	som
	)			const [inline]

Applies a sammons mapping to the given som and draws the resulting grid.

Please not that the sammonsMapping does not respect the orientation in the image plane. Thus, the result might be rotated by an arbitrary angle.

template<typename T >

bool lti::SOFM2DVisualizer::uMatrix	(	drawBase< T > &	drawer,
		const SOFM2D &	som
	)			const [inline]

Draws the unified distane matrix of the given som.
