Constructor Detail

EllipseDescriptor

public EllipseDescriptor()

Constructor.

EllipseDescriptor

public EllipseDescriptor(int t)

Constructor/

Parameters:

t - Time corresponding to this cell.

EllipseDescriptor

public EllipseDescriptor(EllipseDescriptor other)

Constructor.

Parameters:

other - Cell to copy.

Method Detail

init

public void init(icy.type.point.Point4D center)

Description copied from interface: CellDescriptor

Initialize the cells parameters.

Specified by:

init in interface CellDescriptor

Parameters:

center - Center of the cell. The fourth component is the initial radius.

getParameters

public double[] getParameters()

Description copied from interface: CellDescriptor

Return the normalize parameters of the cell.

Specified by:

getParameters in interface CellDescriptor

setParameters

public void setParameters(double[] parameters)

Description copied from interface: CellDescriptor

Set all the parameters of the cell.

Specified by:

setParameters in interface CellDescriptor

Parameters:

parameters - Normalized parameters. The last element has to be the radius obtained from @ref getParameters().

energy

public double energy()

Description copied from interface: CellDescriptor

Energy of the cell.

Specified by:

energy in interface CellDescriptor

computeEnergy

public double computeEnergy(ImageDescriptor imgInt)

Description copied from interface: CellDescriptor

Compute the energy of the cell. The energy is computed with the formula: \f[ E = \frac{\left(\sqrt(2)\int_{\Omega_{shell}} mask\left(\textbf{x}\right)~d\Omega - \int_{\Omega_{cell}} mask\left(\textbf{x}\right)~d\Omega\right) - \int_{\Omega_{cell}} mask\left(\textbf{x}\right)~d\Omega}{Volume_{cell}} \f] Shell design a scaled version of the cell by a factor \f$\sqrt(2)\f$ and \f$\Omega\f$ is the surface of the cell.

Specified by:

computeEnergy in interface CellDescriptor

isClosedTo

public boolean isClosedTo(CellDescriptor other)

Description copied from interface: CellDescriptor

Test if two cells can be considered as equal.

Specified by:

isClosedTo in interface CellDescriptor

Parameters:

other - Other cell to be compared with. Must be of the same type (EllipseDescriptor or EllipsoidDescriptor).

Returns:

Return true it the two cells are closed enough to be considered as equal.
