Method Detail

countPixelsOfClass

public int countPixelsOfClass(int[][] CLASSES,
                              int classNumber)

Counts the pixel of a given object class in the given object CLASSES-map of the image.

Parameters:

CLASSES - A 2-dimensional Array containing the colour classification information for each pixel in the image.

classNumber - An Integer to count all pixel belonging to one object class.

Returns:

An Integer containing all pixel of the specified colour identified in the image.

morphologyTransform

public int morphologyTransform(int[][] CLASSES,
                               int classNumber)

Counts the pixel of a given object class. Also applies the morphological operation "opening" to lower the noise level.

Parameters:

CLASSES - A 2-dimensional Array containing the colour classification information for each pixel in the image.

classNumber - An Integer to count all pixel belonging to one object class.

Returns:

An Integer containing all pixel of the specified colour identified in the image.

drawImageScaling

public void drawImageScaling(ij.ImagePlus img,
                             double pixelPerMM)

Sets the scaling according to the given pixel-per-millimeter calibration and draws a calibration bar into the given image of 100mm length.

Parameters:

img - An ImagePlus object containing the analysed image.

pixelPerMM - An Integer to define how many pixel correspond to how many millimetre in the image.

drawContour

public void drawContour(int[][] CLASSES,
                        ij.ImagePlus img,
                        int classNumber)

Draws the outline around all areas of a specified class into the specified image. This is achieved by edge detection on a binary mask image of the given class, and by transferring those edges into the original image.

Parameters:

CLASSES - A 2-dimensional Array containing the colour classification information for each pixel in the image.

img - An ImagePlus object containing the analysed image.

classNumber - An Integer to count all pixel belonging to one object class.

drawRegions

public void drawRegions(ij.ImagePlus img,
                        java.util.ArrayList<java.util.Hashtable<java.lang.String,java.lang.String>> regions)

Visualises the regions by drawing them as rectangular or oval shapes into the specified image.

Parameters:

img - An ImagePlus object containing the analysed image.

regions - An ArrayList containing the region parameters in a Hashtable.

displayClassificationData

public ij.ImagePlus displayClassificationData(int[][] CLASSES,

                                              java.lang.String title,
                                              int classNumber)

Displays the CLASSES classification data, but only for the chosen class.

Parameters:

title - The image title.

classNumber - An Integer to count all pixel belonging to one object class.

Returns:
