Member Data Documentation

bool lti::axOGDFeature::parameters::computeEdgeOrientation

If true, the angles in the thetaX channels will be fixed to be perpendicular to the edges.

If false, these angles will be keeped to represent the phase of the energy components as described in the original paper.

Note that this parameter only changes the content of the channels thetaX returned by apply(const channel&,channel&,channel&) and apply(const channel&,channel&,channel&,channel&,channel&) methods.

Default value: true

bool lti::axOGDFeature::parameters::considerPhase

If true, the feature vector will contain also phase information which is NOT rotation invariant.

Default: false

bool lti::axOGDFeature::parameters::gaussian

Use Gaussian kernel.

If gaussian is true, for the local features a gaussian kernel is used, with the given size (windowSize) and variance. If false, a square kernel is used, with the given windowSize. Default: true

int lti::axOGDFeature::parameters::levels

Number of levels used.

Default 4

int lti::axOGDFeature::parameters::ogdOrder

Order of the derivative being used.

The valid range by now is 1 or 2. Default: 2

int lti::axOGDFeature::parameters::ogdSize

Size of the ODG filter kernels used.

Default: 13

double lti::axOGDFeature::parameters::ogdVariance

Variance of the base gaussian used in the OGDs Default: 2.0.

bool lti::axOGDFeature::parameters::voices

Specify if a second set of levels should be generated, using a standard deviation equal to the one of the original set multiplied with a factor sqrt(2).

This allows a better resolution of the "resolution"-axis. Default: true

int lti::axOGDFeature::parameters::windowSize

Window size for the extraction of local features.

This is the size of the gaussian kernel is "gaussian" is true, or the size of the square window, if a faster square kernel is chosen. Default : 13 (13x13 window)

double lti::axOGDFeature::parameters::windowVariance

If "gaussian" is true, this value gives the variance to be used.

Default: -1 (i.e. use default variance for the given windowSize
