Method Summary

Modifier and Type	Method and Description
boolean	initEnergy(SnakeOptimizerCoupled o) Init routine which is called once before the energy is actually used.
boolean	requiresCounterClockwiseContourSorting() Ask energy if contour points need to sorted counter-clockwise.

Method Detail

initEnergy

boolean initEnergy(SnakeOptimizerCoupled o)
            throws MTBSnakeException

Init routine which is called once before the energy is actually used.

In this routine global parameter settings can be handled or other initialization stuff be done. Snake optimizers are supposed to call this routine once before they actual use of the energy. If no stuff needs to be done in advance the routine should at least return true.

Parameters:

o - Calling snake optimizer.

Returns:

true if init was successful

Throws:

MTBSnakeException

updateStatus

void updateStatus(SnakeOptimizerCoupled o)
           throws MTBSnakeException

Update internal state of energy object prior to querying derivatives and so on.

Throws:

MTBSnakeException

requiresCounterClockwiseContourSorting

boolean requiresCounterClockwiseContourSorting()

Ask energy if contour points need to sorted counter-clockwise.

Returns:

If true, the energy expects a counter-clockwise sorting.

requiresOverlapMask

boolean requiresOverlapMask()

Ask energy if an overlap mask for all snakes jointly optimized is required.

Returns:

If true, the energy expects an overlap mask to be available.
