	)

static

Display cylinder limbs as two 2D lines with coordinates $(\rho, \theta)$ expressed in the image plane. These coordinates are obtained after perspective projection of the cylinder.

Parameters

rho1,theta1	: Cylinder first limb parameters $(\rho, \theta)$ expressed in the image plane.
rho2,theta2	: Cylinder second limb parameters $(\rho, \theta)$ expressed in the image plane.
cam	: Camera intrinsic parameters.
I	: Image.
color	: Color to use to display the feature.

static

Display an ellipse with parameters $(x, y, n_{20}, n_{11}, n_{02})$ expressed in the image plane. These parameters are obtained after perspective projection of a 3D circle (see vpCircle) or a sphere (see vpSphere).

Parameters

x,y,n20,n11,n02	: Ellipse parameters where: are the normalized coordinates of the ellipse center, respectively along the horizontal and vertical axis in the image plane. $n_{20}, n_{11}, n_{02}$ are the second order centered moments of the ellipse normalized by its area (i.e., such that $n_{ij} = \mu_{ij}/a$ where $\mu_{ij}$ are the centered moments and a the area) expressed in the image plane.
cam	: Camera intrinsic parameters.
I	: Image.
color	: Color to use to display the feature.
thickness	: Thickness of the feature representation.
