Implements ImageJ's Analyze Particles command.

        for each line do
                for each pixel in this line do
                        if the pixel value is "inside" the threshold range then
                                trace the edge to mark the object
                                do the measurement
                                fill the object with a color outside the threshold range
                        else
                                continue the scan

Constructor Detail

ParticleAnalyzer

public ParticleAnalyzer(int options,
                        int measurements,
                        ResultsTable rt,
                        double minSize,
                        double maxSize,
                        double minCirc,
                        double maxCirc)

Constructs a ParticleAnalyzer.

Parameters:

options - a flag word created by Oring SHOW_RESULTS, EXCLUDE_EDGE_PARTICLES, etc.

measurements - a flag word created by ORing constants defined in the Measurements interface

rt - a ResultsTable where the measurements will be stored

minSize - the smallest particle size in pixels

maxSize - the largest particle size in pixels

minCirc - minimum circularity

maxCirc - maximum circularity

ParticleAnalyzer

public ParticleAnalyzer(int options,
                        int measurements,
                        ResultsTable rt,
                        double minSize,
                        double maxSize)

Constructs a ParticleAnalyzer using the default min and max circularity values (0 and 1).

Default constructor

Method Detail

setup

public int setup(java.lang.String arg,
                 ImagePlus imp)

Description copied from interface: PlugInFilter

This method is called once when the filter is loaded. 'arg', which may be blank, is the argument specified for this plugin in IJ_Props.txt or in the plugins.config file of a jar archive containing the plugin. 'imp' is the currently active image. This method should return a flag word that specifies the filters capabilities.

For Plugin-filters specifying the FINAL_PROCESSING flag, the setup method will be called again, this time with arg = "final" after all other processing is done.

Specified by:

setup in interface PlugInFilter

run

public void run(ImageProcessor ip)

Description copied from interface: PlugInFilter

Filters use this method to process the image. If the SUPPORTS_STACKS flag was set, it is called for each slice in a stack. With CONVERT_TO_FLOAT, the filter is called with the image data converted to a FloatProcessor (3 times per image for RGB images). ImageJ will lock the image before calling this method and unlock it when the filter is finished. For PlugInFilters specifying the NO_IMAGE_REQUIRED flag and not the DONE flag, run(ip) is called once with the argument null.

Specified by:

run in interface PlugInFilter

showDialog

public boolean showDialog()

Displays a modal options dialog.

analyze

public boolean analyze(ImagePlus imp)

Performs particle analysis on the specified image. Returns false if there is an error.

analyze

public boolean analyze(ImagePlus imp,
                       ImageProcessor ip)

Performs particle analysis on the specified ImagePlus and ImageProcessor. Returns false if there is an error.

saveResults

protected void saveResults(ImageStatistics stats,
                           Roi roi)

Saves statistics for one particle in a results table. This is a method subclasses may want to override.

drawParticle

protected void drawParticle(ImageProcessor drawIP,
                            Roi roi,
                            ImageStatistics stats,
                            ImageProcessor mask)

Draws a selected particle in a separate image. This is another method subclasses may want to override.

getOutputImage

public ImagePlus getOutputImage()

Returns the "Outlines", "Masks", "Elipses" or "Count Masks" image, or null if "Nothing" is selected in the "Show:" menu.

setHideOutputImage

public void setHideOutputImage(boolean hideOutputImage)

Set 'hideOutputImage' true to not display the "Show:" image.

savePreferences

public static void savePreferences(java.util.Properties prefs)

Called once when ImageJ quits.
