Detailed Description

Functionality computation for centered and normalized moment feature. Computes the interaction matrix associated with vpMomentGravityCenterNormalized.

It computes the interaction matrices for $ (x_n,y_n) $ . The interaction matrix for the moment feature has the following expression:

In the discrete case:
$L_{x_n} = { \left[ \begin {array}{c} -Ax_{{n}}\theta+ \left( x_{{n}}e_{{1,1}}-y_{ {n}} \right) B-a_{{n}}C\\ \noalign{\medskip}Ax_{{n}}e_{{1,1}}+Bx_{{n}} \theta\\ \noalign{\medskip} \left( -a_{{n}}-w_{{y}} \right) A+Bw_{{x}} \\ \noalign{\medskip}a_{{n}}e_{{1,1}}{\it NA}+ \left( \eta_{{1,0}}e_{{ 1,1}}+\eta_{{0,1}}-e_{{2,1}}-x_{{g}}e_{{1,1}}+\eta_{{0,1}}\theta \right) x_{{n}}+ \left( \eta_{{1,0}}-x_{{g}}\theta \right) y_{{n}}-{ \frac {x_{{n}}\eta_{{0,3}}}{{\it NA}}}\\ \noalign{\medskip} \left( -1+ \theta \right) a_{{n}}{\it NA}+ \left( e_{{1,2}}+x_{{g}}-\eta_{{0,1}}e _{{1,1}}-2\,\eta_{{1,0}}+e_{{3,0}}+ \left( -x_{{g}}+\eta_{{1,0}} \right) \theta \right) x_{{n}}+e_{{1,1}}x_{{g}}y_{{n}}-a_{{n}} \\ \noalign{\medskip}y_{{n}}\end {array} \right] }^t L_{y_n} = { \left[ \begin {array}{c} \left( 1-\theta \right) y_{{n}}A+y_{{n}}e_{ {1,1}}B\\ \noalign{\medskip} \left( -x_{{n}}+y_{{n}}e_{{1,1}} \right) A+ \left( -1+\theta \right) y_{{n}}B-a_{{n}}C\\ \noalign{\medskip}-Aw_ {{y}}+ \left( -a_{{n}}+w_{{x}} \right) B\\ \noalign{\medskip}\theta\,a _{{n}}{\it NA}+ \left( -e_{{2,1}}+\eta_{{1,0}}e_{{1,1}}+\eta_{{0,1}}-x _{{g}}e_{{1,1}}+ \left( \eta_{{0,1}}-y_{{g}} \right) \theta \right) y_ {{n}}+a_{{n}}-{\frac {y_{{n}}\eta_{{0,3}}}{{\it NA}}} \\ \noalign{\medskip}-a_{{n}}e_{{1,1}}{\it NA}-x_{{n}}\eta_{{0,1}}+ \left( e_{{1,2}}+y_{{g}}e_{{1,1}}-\eta_{{0,1}}e_{{1,1}}+x_{{g}}+e_{{3 ,0}}-2\,\eta_{{1,0}}+ \left( -x_{{g}}+\eta_{{1,0}} \right) \theta \right) y_{{n}}\\ \noalign{\medskip}-x_{{n}}\end {array} \right] }^t$
In the dense case:
$L_{x_n} = { \left[ \begin {array}{c} -a_{{n}}C-1/2\,Ax_{{n}}-By_{{n}} \\ \noalign{\medskip}1/2\,Bx_{{n}}\\ \noalign{\medskip} \left( -a_{{n} }-w_{{y}} \right) A+Bw_{{x}}\\ \noalign{\medskip} \left( 4\,\eta_{{1,0 }}-1/2\,x_{{g}} \right) y_{{n}}+4\,a_{{n}}\eta_{{1,1}}+4\,x_{{n}}\eta_ {{0,1}}\\ \noalign{\medskip} \left( -4\,\eta_{{1,0}}+1/2\,x_{{g}} \right) x_{{n}}+ \left( -1-4\,\eta_{{2,0}} \right) a_{{n}} \\ \noalign{\medskip}y_{{n}}\end {array} \right] }^t L_{y_n} = { \left[ \begin {array}{c} 1/2\,Ay_{{n}}\\ \noalign{\medskip}-1/2\,By_{ {n}}-a_{{n}}C-Ax_{{n}}\\ \noalign{\medskip}-Aw_{{y}}+ \left( -a_{{n}}+ w_{{x}} \right) B\\ \noalign{\medskip}4\,\theta\,a_{{n}}{\it NA}+ \left( 4\,\eta_{{0,1}}-1/2\,y_{{g}} \right) y_{{n}}+a_{{n}} \\ \noalign{\medskip} \left( -4\,\eta_{{1,0}}+1/2\,x_{{g}} \right) y_{ {n}}-4\,a_{{n}}\eta_{{1,1}}-4\,x_{{n}}\eta_{{0,1}} \\ \noalign{\medskip}-x_{{n}}\end {array} \right] }^t$
with:
- $e_{i,j}=\frac{\mu_{i,j}}{NA}$
- $NA=\mu_{2,0}+\mu_{0,2}$
- $\theta=\frac{\eta_{0,2}}{NA}$
- $\eta$ is the centered and normalized moment.

These interaction matrices may be selected afterwards by calling vpFeatureMomentGravityCenterNormalized::interaction. The selection is done by the following methods: vpFeatureMomentGravityCenterNormalized::selectXn for $L_{x_{n}}$ and vpFeatureMomentGravityCenterNormalized::selectYn for $L_{y_{n}}$ . You can use these shortcut selectors as follows:

task.addFeature(db_src.getFeatureGravityNormalized(),db_dst.getFeatureGravityNormalized(),vpFeatureMomentGravityCenterNormalized::selectXn() | vpFeatureMomentGravityCenterNormalized::selectYn());

The behaviour of this feature is very similar to vpFeatureMomentGravityCenter which also contains a sample code demonstrating a selection.

This feature is often used in moment-based visual servoing to control the planar translation parameters.

Minimum vpMomentObject order needed to compute this feature: 2 in dense mode and 3 in discrete mode.

		double	A_,

	)

inline

Initializes the feature with information about the database of moment primitives, the object plane and feature database.

A_	: Plane coefficient in a $A \times x+B \times y + C = \frac{1}{Z}$ plane.
B_	: Plane coefficient in a $A \times x+B \times y + C = \frac{1}{Z}$ plane.
C_	: Plane coefficient in a $A \times x+B \times y + C = \frac{1}{Z}$ plane.

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.

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_,

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.
