Class BackgroundSubtracter
java.lang.Object
ij.plugin.filter.BackgroundSubtracter
- All Implemented Interfaces:
- PlugInFilter
public class BackgroundSubtracter
- extends java.lang.Object
- implements PlugInFilter
Implements ImageJ's Subtract Background command. Based on
the NIH Image Pascal version by Michael Castle and Janice
Keller of the University of Michigan Mental Health Research
Institute. Rolling ball algorithm inspired by Stanley
Sternberg's article, "Biomedical Image Processing",
IEEE Computer, January 1983.

BackgroundSubtracter
public BackgroundSubtracter()
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. 'imp' is the currently active image.
This method should return a flag word that specifies the
filters capabilities.
- 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. ImageJ will lock the image before calling
this method and unlock it when the filter is finished.

showDialog

subtractRGBBackround
public void subtractRGBBackround(ColorProcessor ip,
int ballRadius)
subtractBackround
public void subtractBackround(ImageProcessor ip,
int ballRadius)
- Implements a rolling-ball algorithm for the removal of smooth continuous background
from a two-dimensional gel image. It rolls the ball (actually a square patch on the
top of a sphere) on a low-resolution (by a factor of 'shrinkfactor' times) copy of
the original image in order to increase speed with little loss in accuracy. It uses
interpolation and extrapolation to blow the shrunk image to full size.
