Class FractalBoxCounter
java.lang.Object
ij.plugin.filter.FractalBoxCounter
- All Implemented Interfaces:
- PlugInFilter
public class FractalBoxCounter
- extends java.lang.Object
- implements PlugInFilter
Calculate the so-called "capacity" fractal dimension. The algorithm
is called, in fractal parlance, the "box counting" method. In the
simplest terms, the routine counts the number of boxes of a given size
needed to cover a one pixel wide, binary (black on white) border.
The procedure is repeated for boxes that are 2 to 64 pixels wide.
The output consists of two columns labeled "size" and "count". A plot
is generated with the log of size on the x-axis and the log of count on
the y-axis and the data is fitted with a straight line. The slope (S)
of the line is the negative of the fractal dimension, i.e. D=-S.
A full description of the technique can be found in T. G. Smith,
Jr., G. D. Lange and W. B. Marks, Fractal Methods and Results in Cellular Morphology,
which appeared in J. Neurosci. Methods, 69:1123-126, 1996.

FractalBoxCounter
public FractalBoxCounter()
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.
- Specified by:
run
in interface PlugInFilter
s2ints
public int[] s2ints(java.lang.String s)
- Breaks the specified string into an array
of ints. Returns null if there is an error.
