Analyze Particles

[Mohamed Tleis]

Dear Members,

I was wondering whether there is a way to apply "analyze particles" on an
ImageProcessor in my java code, instead of ImagePlus; Currently I am using
the IJ.run command to run the analyzer; But I want to run it only on my
ImageProcessor without having to create an ImagePlus for it;

I had a look at the ij.plugin.filter.Analyzer; but it seems not to have
methods to work with ImageProcessors directly;

Any suggestions?

Best Regards,
M. Tleis

Hi,

here a small example that can be helpful :

plus=IJ.getImage()
rt=ResultsTable.getResultsTable();
if(rt==null) rt=new ResultsTable();
manager=RoiManager.getInstance();
if(manager==null) manager=new RoiManager();

analyser=new
ParticleAnalyzer(ParticleAnalyzer.SHOW_RESULTS+ParticleAnalyzer.ADD_TO_MANAGER,
Measurements.AREA, rt, 10, Double.MAX_VALUE, 0,1);

analyser.analyze(plus);
rt.updateResults(); rt.show("Results");

have a look to class Measurements to selct the measurements and class
ParticleAnalyzer for options with analyse paticles.

Hi Mohammed,

the Particle Analyzer needs to know the spatial image calibration, so it only works with an ImagePlus, not with a bare an ImageProcessor (an ImageProcessor has no spatial calibration).

If you have only an ImageProcessor, you can create an ImagePlus with default calibration from it:

    ImagePlus imp = new ImagePlus("any title", ip);
