Member Enumeration Documentation

enum lti::regionShapeFeatures::parameters::basisFunctionsType

Basis functions that can be used.

Enumerator:

MPEG7	Use MPEG-7 non-orthogonal basis functions.
OrthoRadial	Similar to the region-shape descriptor of MPEG-7, but with an orthogonal radial basis function.
Zernike	use Zernike moments

Member Function Documentation

virtual functor::parameters* lti::regionShapeFeatures::parameters::clone

(

)

const [virtual]

returns a pointer to a clone of the parameters

Reimplemented from lti::globalFeatureExtractor::parameters.

parameters& lti::regionShapeFeatures::parameters::copy

(

const parameters &

other

)

copy the contents of a parameters object

Parameters:

other

the parameters object to be copied

Returns:

a reference to this parameters object

Reimplemented from lti::globalFeatureExtractor::parameters.

const char* lti::regionShapeFeatures::parameters::getTypeName

(

)

const [virtual]

returns name of this type

Reimplemented from lti::globalFeatureExtractor::parameters.

parameters& lti::regionShapeFeatures::parameters::operator=

(

const parameters &

other

)

copy the contents of a parameters object

Parameters:

other

the parameters object to be copied

Returns:

a reference to this parameters object

virtual bool lti::regionShapeFeatures::parameters::read	(	ioHandler &	handler,
		const bool	complete = true
	)			[virtual]

read the parameters from the given ioHandler

Parameters:

	handler	the ioHandler to be used
	complete	if true (the default) the enclosing begin/end will be also written, otherwise only the data block will be written.

Returns:

true if write was successful

Reimplemented from lti::functor::parameters.

virtual bool lti::regionShapeFeatures::parameters::write	(	ioHandler &	handler,
		const bool	complete = true
	)			const [virtual]

write the parameters in the given ioHandler

Parameters:

	handler	the ioHandler to be used
	complete	if true (the default) the enclosing begin/end will be also written, otherwise only the data block will be written.

Returns:

true if write was successful

Reimplemented from lti::functor::parameters.

Member Data Documentation

basisFunctionsType lti::regionShapeFeatures::parameters::basisFunctionSet

Which basis function set should be used.

Default: MPEG7

int lti::regionShapeFeatures::parameters::maskSize

In order to achieve scale invariance, the given mask will always be first scaled to fit into square mask of the given size at one side.

Default size: 65

bool lti::regionShapeFeatures::parameters::polar

Specify if the computed coefficients should be in cartesic form (false) (i.e.

real and imaginary parts) or polar form (true) (i.e. magnitude and phase).

Default value: true (i.e. polar form: magnitude and phase)

point lti::regionShapeFeatures::parameters::size

size of the descriptor matrix.

The x component will correspond to the number of angular frequencies to be used, and the y component to the number of radial frequencies.

The feature vectors will have size.x*size.y elements.

For Zernike moments the matrix is symmetric with (size.y,size.y)

Default value: (12 , 3)
