A macro something like the following should work. Note that it assumes, like the NIH Image version, that objects are black and background is white and that black pixels have a value of 255.

-wayne

  macro "Fractal Dilation" {
     iterations = 64;
     run("Clear Results");
     setOption("BlackBackground", false);
     run("Make Binary"); // needed if image is not binary
     for (i=0; i<=iterations; i++) {
        showProgress(i, iterations);
        getRawStatistics(n, mean, min, max, std, hist);
        setResult("i*2+1", i, i*2+1);
        setResult("hist[255]", i, hist[255]);
        setResult("hist[255]/(i*2+1)", i, hist[255]/(i*2+1));
        run("Options...", "iterations=1 count=1 do=Dilate");
      }
     updateResults;
  }
