Class Mask

java.lang.Object

omero.gateway.util.Mask

public class Mask
extends java.lang.Object

Provides some utility methods for dealing with mask ROIs.

Method Summary

Modifier and Type	Method and Description
static MaskData	createCroppedMask(boolean[][] mask) Creates a mask ROI; automatically crop to its bounding box.
static MaskData	createCroppedMask(int[][] mask) Creates a mask ROI; automatically crop to its bounding box.
static java.util.List<MaskData>	createCroppedMasks(int[][] masks) Creates mask ROIs from the given integer array where each single mask ROI is specified by a specific integer.
static java.util.List<MaskData>	createCroppedMasks(int[] masks, int width) Creates mask ROIs from the given integer array where each single mask ROI is specified by a specific integer.
static int[][]	fold(int[] array, int length) Breaks a one-dimensional array into 'length' chunks, forming a two-dimensional array, e.g.
static int[]	unfold(int[][] array) Transforms a 2 dimensional array into a one dimensional array; the opposite of the fold method.

Method Detail

createCroppedMask

public static MaskData createCroppedMask(int[][] mask)

Creates a mask ROI; automatically crop to its bounding box. (sets X, Y, width and height accordingly)

Parameters:

mask - The binary mask (int[width][height]) covering the whole image

Returns:

The mask ROI

createCroppedMask

public static MaskData createCroppedMask(boolean[][] mask)

Creates a mask ROI; automatically crop to its bounding box. (sets X, Y, width and height accordingly)

Parameters:

mask - The binary mask (boolean[width][height]) covering the whole image

Returns:

The mask ROI

createCroppedMasks

public static java.util.List<MaskData> createCroppedMasks(int[][] masks)

Creates mask ROIs from the given integer array where each single mask ROI is specified by a specific integer.

Parameters:

masks - The masks (int[width][height]) covering the whole image.

Returns:

The mask ROIs

createCroppedMasks

public static java.util.List<MaskData> createCroppedMasks(int[] masks,
                                                          int width)

Creates mask ROIs from the given integer array where each single mask ROI is specified by a specific integer.

Parameters:

masks - The masks covering the whole image.

width - The width of the image

Returns:

The mask ROIs

fold

public static int[][] fold(int[] array,
                           int length)

Breaks a one-dimensional array into 'length' chunks, forming a two-dimensional array, e.g.

 int[] x = 0 1 2 3 4 5 6 7 8 9

 using length = 4 will be transformed to

 int[][] y =
 [0 1 2 3]
 [4 5 6 7]
 [8 9 0 0]
 

Parameters:

array - An int array

length - The length of the chunks

Returns:

Two dimensional array

unfold

public static int[] unfold(int[][] array)

Transforms a 2 dimensional array into a one dimensional array; the opposite of the fold method. E.g.

 int[][] y =
 [0 1 2 3]
 [4 5 6 7]
 [8 9 0 0]

 would transformed into

 int[] x = 0 1 2 3 4 5 6 7 8 9 0 0
 

Parameters:

array - An int array

Returns:

The one dimensional array
