public abstract class CalculateLevel
extends NullParametersBean<CalculateLevel>

Calculates a threshold-level from a histogram.

A well-behaved CalculateLevel should implements equals(java.lang.Object) and hashCode(). If this is not possible, these methods should instead throw a run-time exception.

Method Details

calculateLevel

public abstract int calculateLevel(Histogram histogram)
                            throws OperationFailedException

Determines a voxel intensity that can be used for thresholding.

Parameters:

histogram - a histogram of voxel-intensities from which a threshold-level can be derived.

Returns:

the threshold-level.

Throws:

OperationFailedException - if a level cannot be successfully calculated.

equals

public abstract boolean equals(Object obj)
