Detailed Description

Functionality computation for centered moment feature. Computes the interaction matrix associated with vpMomentCentered.

The interaction matrix for the feature is defined in [23], equation (17). This vpFeatureMoment, as well as it's corresponding moment primitive is double-indexed. The interaction matrix $ L_{\mu_{ij}} $ is obtained by calling vpFeatureMomentBasic::interaction (i,j) and is associated to $ \mu_{ij} $ obtained by vpFeatureMomentCentered::get (i,j).

vpFeatureMomentCentered computes interaction matrices all interaction matrices up to vpMomentObject::getOrder()-1.

Attention
The maximum order reached by vpFeatureMomentBasic is NOT the maximum order of the vpMomentObject, it is one unit smaller. For example if you define your vpMomentObject up to order n then vpFeatureMomentBasic will be able to compute interaction matrices up to order n-1 that is $ L_{m_{ij}} $ with $ i+j<=n-1 $.

This feature depends on:

Member Function Documentation

void vpFeatureMomentCentered::compute_interaction ( void  )
virtual

Computes interaction matrix for centered moment. Called internally. The moment primitives must be computed before calling this. This feature depends on:

Reimplemented from vpFeatureMoment.

unsigned int vpBasicFeature::dimension_s ( )

Return the dimension of the feature vector $\bf s$.

void vpFeatureMoment::display ( const vpCameraParameters &  cam,
const vpImage< unsigned char > &  I,
const vpColor &  color = vpColor::green,
unsigned int  thickness = 1 
) const
virtualinherited

Not implemented since visual representation of a moment doesn't often make sense.

Implements vpBasicFeature.

void vpFeatureMoment::display ( const vpCameraParameters &  cam,
const vpImage< vpRGBa > &  I,
const vpColor &  color = vpColor::green,
unsigned int  thickness = 1 
) const
virtualinherited

Not implemented since visual representation of a moment doesn't often make sense.

Implements vpBasicFeature.

Definition at line 128 of file vpFeatureMoment.cpp.

vpBasicFeature * vpFeatureMoment::duplicate ( ) const
virtualinherited

Duplicates the feature into a vpGenericFeature harbouring the same properties. The resulting feature is of vpMomentGenericFeature type. While it still can compute interaction matrices and has acces to it's moment primitive, it has lost all precise information about its precise type and therefore cannot be used in a feature database.

Returns
The corresponding feature.

vpColVector vpBasicFeature::error ( const vpBasicFeature &  s_star,

Compute the error between two visual features from a subset of the possible features.

Returns
Interaction matrix corresponding to the moment

vpMatrix vpFeatureMoment::interaction ( const unsigned int  select = FEATURE_ALL)
virtualinherited

Retrieves the interaction matrix. No computation is done.

Parameters
select: Feature selector.
Returns
The corresponding interaction matrix.

There is no rule about the format of the feature selector. It may be different for different features. For example, for vpFeatureMomentBasic or vpFeatureMomentCentered features, select may refer to the $ (i,j) $ couple in the $ j \times order + i $ format, but for vpFeatureMomentCInvariant the selector allows to select couples $ (i,j,k,l...) $ in the following format: 1 << i

  • 1 << j + 1 << k + 1 << l.

void vpFeatureMoment::update ( double  A_,
double  B_,
double  C_ 
)
inherited

Updates the interaction matrices with the image plane the camera is facing. The plane must be in the format: $ \frac{1}{Z}=Ax+By+C $ . The moment primitives MUST be updated before calling this function.

This method also computes the interaction matrix. Therefore, you must call vpFeatureMoment::update before calling vpFeatureMoment::interaction.

Attention
The behaviour of this method is not the same as vpMoment::update which only acknowledges the new object. This method also computes the interaction matrices.
Parameters
A_: A coefficient of the plane.
B_: B coefficient of the plane.
C_: C coefficient of the plane.
