ImageStatistics

[Lenka Polaskova]

Hello,
I am writting a new plugin in java and I need to get and use image statistics displayed in measurements result table. For now I use a method getStatistics() that allows me to measure Area, Mean, Mode, Min, Max, StdDev, RX, RY statistics and save them into my variables. But the measurements result table offers to read other statistics such as IntDen, RawDen, XM, YM and else. Also a command Color Histogram displays a measurements result table, where statistics such as red mean, red mode, green mean and else are. Please can someone tell me how could I get these orther statistics and save them in variables or text window?
I would be very grateful for advice
Lenka

Hi Lenka,

you can have a look at ij.plugin.filter.Analyzer, method 'saveResults' to see how the values not directly available from the ImageStatistics are calculated:

E.g. you will there find:
  rt.addValue(ResultsTable.INTEGRATED_DENSITY,stats.area*stats.mean);
So, the integrated density is stats.area*stats.mean, with 'stats' being the ImageStatistics.

Hello
thank a lot for your quick response, now it works. But unfortunatelly,
there is another problem. I cannot achieve an image type convertion from
8-bit grayscale to RGB. I've tried to call ip.convertToRGB() method or
IJ.run("RGB Color") method but without any luck. Any ideas?

Hi Lenka,

first a general remark: please start a new thread for a new problem, don't
simply reply to an unrelated topic.

Both of your versions to convert an image to RGB should work:
  ImageProcessor myNewRgbProcessor = ip.convertToRGB();
and, if the image is the current foreground image,
  IJ.run("RGB Color");
It would be better to specify also the ImagePlus (here named imp), in case
a simultaneous process changes the foreground image (remember that Java is
multi-threaded):
  IJ.run(imp, "RGB Color");
Thereafter, of course, you have to use imp.getProcessor() to get the
converted ImageProcessor.
