Member Function Documentation

virtual functor::parameters* lti::axLocalRegions::parameters::clone

(

)

const [virtual]

returns a pointer to a clone of the parameters

Reimplemented from lti::transform::parameters.

parameters& lti::axLocalRegions::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::transform::parameters.

const char* lti::axLocalRegions::parameters::getTypeName

(

)

const [virtual]

returns name of this type

Reimplemented from lti::transform::parameters.

parameters& lti::axLocalRegions::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::axLocalRegions::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::axLocalRegions::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

int lti::axLocalRegions::parameters::binsInOrientationHistogram

Number of bins used in the orientation histogram.

Default value 32

int lti::axLocalRegions::parameters::firstLevel

first level to consider.

Must be greater 0 and smaller or equal than lastLevel.

Default: 2

int lti::axLocalRegions::parameters::firstMaximumFilterSize

To detect the local maxima, a lti::maximumFilter is used.

The size of the kernel used for the firstLevel is the one given here. It should be an odd number.

Default value: 5

int lti::axLocalRegions::parameters::lastLevel

last level to consider.

Must be greater or equal than firstLevel

Default: 6

float lti::axLocalRegions::parameters::maximumFilterAdaption

The size of the used kernel can be reduced for each higher level in the pyramid.

This value should be less or equal 1.0. Internally, the kernel value used will be always rounded to an odd integer number greater or equal 3.

Default value: 1.0, i.e. do not change the filter size.

double lti::axLocalRegions::parameters::orientationWindowFactor

The gaussian used as window for the orientation histograms will have a std.

deviation equal to this factor multiplied with the std. deviation of the location scale.

Default value: 3

vector<float> lti::axLocalRegions::parameters::saliencyThreshold

Saliency threshold values per level.

The elements of the vector should be between 0 and 1. The element of the vector with the same index as a any given level of the internally computed pyramid will be multiplied with the maximum value in that level. Only those locations which surpass this value are then considered as relevant and inserted in the locations list. The size of the vector should be at least lastLevel+1. Otherwise, the last value will be taken for all the remaining levels.

Default value: vector of size 1 with the value 0.1,
