You can get the ResultsTable using
ResultsTable rt = ResultsTable.getResultsTable();
You can get a list of the ROIs using
Overlay rois = imp.getOverlay();
if you use the show="Overlay Outlines" option that was added to the particle analyzer in ImageJ 1.44b. This works because because an Overlay is basically just a list of ROIs.
Here is an example:
imp = IJ.openImage("
http://rsb.info.nih.gov/ij/images/blobs.gif");
IJ.setAutoThreshold(imp, "MaxEntropy");
IJ.run("Set Measurements...", "area mean");
IJ.run(imp, "Analyze Particles...", "show=[Overlay Outlines] clear");
rois = imp.getOverlay();
rt = ResultsTable.getResultsTable();
for (i=0; i<rois.size(); i++)
IJ.log(i+" "+rois.get(i)+", area="+rt.getValue("Area", i));
