Method Summary

Modifier and Type	Method and Description
boolean	dialogItemChanged(ij.gui.GenericDialog gd, java.awt.AWTEvent e) Read the video frame rate from user input
boolean	doDialog() Displays the dialog with the input field for the frame rate
void	run(ij.process.ImageProcessor theIp) For this class, displays the dialog to get the frame rate.
int	setup(java.lang.String arg, ij.ImagePlus imp) Indicate that we need greyscale images and also that the original image is not changed ( a new output image is generated instead)

Field Detail

gd

protected static ij.gui.GenericDialog gd

Reference to the dialog shown in this plugin

imp

protected ij.ImagePlus imp

Holds a reference to the primary ImagePlus object associated with this plugin

ip

protected ij.process.ImageProcessor ip

image processor at the time of starting the analysis

frame_rate

public static double frame_rate

Video frame rate, in frame/s

Constructor Detail

LocalFrequency

public LocalFrequency()

Method Detail

dialogItemChanged

public boolean dialogItemChanged(ij.gui.GenericDialog gd,
                                 java.awt.AWTEvent e)

Read the video frame rate from user input

Specified by:

dialogItemChanged in interface ij.gui.DialogListener

setup

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

Indicate that we need greyscale images and also that the original image is not changed ( a new output image is generated instead)

Specified by:

setup in interface ij.plugin.filter.PlugInFilter

run

public void run(ij.process.ImageProcessor theIp)

For this class, displays the dialog to get the frame rate. Then pefroms stack projection with division by 255 to get the number of beats, which is then extrapolated to beats per minute. Output: Creates a plain image with the xy dimensions of the stack, showing the local beating calcium wave frequency (32 bit)

Specified by:

run in interface ij.plugin.filter.PlugInFilter

doDialog

public boolean doDialog()

Displays the dialog with the input field for the frame rate

Returns:

true upon success, false otherwise (including user cancel)
