Method Detail

init

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

Initialize the cells parameters.

Parameters:

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

energy

double energy()

Energy of the cell.

getParameters

double[] getParameters()

Return the normalize parameters of the cell.

setParameters

void setParameters(double[] parameters)

Set all the parameters of the cell.

Parameters:

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

computeEnergy

double computeEnergy(ImageDescriptor imgInt)

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.

Parameters:

mask - Binarized image used to compute the energy of the cell.

isClosedTo

boolean isClosedTo(CellDescriptor other)

Test if two cells can be considered as equal.

Parameters:

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

tolerance - Threshold criterion.

Returns:

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