All Known Implementing Classes:

public interface MTBSegmentationInterface

Interface for representing 2D and 3D segmentations of image data.

A segmentation representation stores for each position within its domain a class label. Labels are assumed to be of positive value or at least equal to zero. It is possible to declare certain positions 'invisible', for example for the purpose of ignoring them in statistical calculations. In addition, each pixel position within the domain of the segmentation can be assigned an individual weight.

Method Detail

getDimension

MTBSegmentationInterface.SegmentationDimension getDimension()

Returns the dimension of the segmentation.

getSizeX

int getSizeX()

Returns the size of the segmentation domain in x direction.

getSizeY

int getSizeY()

Returns the size of the segmentation domain in y direction.

getSizeZ

int getSizeZ()

Returns the size of the segmentation domain in z direction.

getNumberOfClasses

int getNumberOfClasses()

Returns the number of classes represented by the segmentation.

getMaxLabel

int getMaxLabel()

Returns the maximal label used in the segmentation representation.

Note that the maximal label is not required to coincide with the number of classes represented by the segmentation. Labels should usually, but do not necessarily need to be positive.

isVisible

boolean isVisible(int x,
                  int y)

True, if position (x,y) is visible.

isVisible

boolean isVisible(int x,
                  int y,
                  int z)

True, if position (x,y,z) is visible.

setVisible

void setVisible(int x,
                int y)

Set position (x,y) visible.

setVisible

void setVisible(int x,
                int y,
                int z)

Set position (x,y,z) visible.

setInvisible

void setInvisible(int x,
                  int y)

Set position (x,y) invisible.

setInvisible

void setInvisible(int x,
