Different histograms in the macro and Java

[Avital Steinberg]

Hi,
I would like to get the same histogram as the one obtained in Analyze,
histogram - using Javascript, and get the values  obtained when clicking on
"List" in the histogram window in ImageJ. (without displaying the histogram)

The problem is that the command recorder records nothing when I click on
list, so it's not clear to me how to get the values after using the command:

IJ.run(imp, "Histogram", "");

Also, if I use the getHistogram function from the ImageProcessor or
ImagePlus class in the Java API, it gives a different histogram. The bin
width is 1, instead of (xmax - xmin)/nBins bin width. I would like to get
the same histogram as the one in Analyze, histogram.

Is there an easy way to do this?

Thanks,
Avital

Hi Avital,

you could look at ij.gui.HistogramWindow, a class you can use in a plugin
or script and has different constructuctors taking bin, min, max values,
etc. Some of them require you to convert to 32 bit image however.

Or, you could try ImagePlus#getStatistics(int mOptions, int nBins, double
histMin, double histMax) and then get the histogram from
ij.process.ImageStatistics#getHistogram();

Regards,
David

Hi David,
I prefer the second suggestion you gave me, since the HistogramWindow class
has constructors that all display the histogram. (I don't want it to be
displayed)

What does int mOptions mean? This is probably exactly the solution I'm
looking for.

Thanks,
Avital

Hi Avital,

the int mOption comes from the Measurements interface. The constants are
defined in the source below. You can add them to get what you want, e.g. if
you call ImagePlus#getStatistics() without arguments it actually calls
getStatistics( AREA+MEAN+MODE+MIN_MAX).

package ij.measure;

public interface Measurements {

public static final int AREA=1,MEAN=2,STD_DEV=4,MODE=8,MIN_MAX=16,
CENTROID=32,CENTER_OF_MASS=64,PERIMETER=128, LIMIT=256, RECT=512,
LABELS=1024,ELLIPSE=2048,INVERT_Y=4096,CIRCULARITY=8192,
SHAPE_DESCRIPTORS=8192,FERET=16384,INTEGRATED_DENSITY=0x8000,
MEDIAN=0x10000, SKEWNESS=0x20000, KURTOSIS=0x40000, AREA_FRACTION=0x80000,
SLICE=0x100000, STACK_POSITION=0x100000, SCIENTIFIC_NOTATION=0x200000,
ADD_TO_OVERLAY=0x400000, NaN_EMPTY_CELLS=0x800000;
/** Maximum number of calibration standard (20) */
public static final int MAX_STANDARDS = 20;

}
