After I run:

ip.setThreshold(stats.mean-multiplier*stats.stdDev,    
2**imp.getBitDepth(), ImageProcessor.RED_LUT)

I have the thresholds associated with the image. I even see the correct
overlay.
However, I cannot figure how to apply these thresholds to the image in
order to create a binary image.

IJ.run(imp, "Convert to Mask", " background=Dark black")

applies one of the automatic threshholding methods, (even though I
removed that option from the argument list).

I tried also, ip.setBinaryThreshold(), but it does not appear to do what
I want (I am not quite sure what it does)

How are thresholds used to create a binary image?

Thanks again in advance
