Enum Constant Detail

classSize

public static final CalcSegmentationStatistics.CalcTargets classSize

Size of individual regions.

classMean

public static final CalcSegmentationStatistics.CalcTargets classMean

Average intensity values of all regions.

For a single region R the average intensity is calculated as follows:

\begin{equation*} \mu(R) = \frac{1}{\sum_{(x,y,z) \in R} w(x,y,z)} \sum_{(x,y,z) \in R} w(x,y,z) \cdot I(x,y,z) \end{equation*}

w is a function assigning an individual weight to each pixel.

classVar

public static final CalcSegmentationStatistics.CalcTargets classVar

Intensity variance within each region.

A region's intensity variance is calculated as follows:

\begin{equation*} \sigma(R) = \frac{1}{\sum_{(x,y,z) \in R} w(x,y,z)} \sum_{(x,y,z) \in R} w(x,y,z) \cdot (I(x,y,z)-\mu(R))^2 \end{equation*}

w is a function assigning an individual weight to each pixel.

Method Detail

values

public static CalcSegmentationStatistics.CalcTargets[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (CalcSegmentationStatistics.CalcTargets c : CalcSegmentationStatistics.CalcTargets.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static CalcSegmentationStatistics.CalcTargets valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
