Thanks Chris, Noel, Wayne and Gary

I know how to do the 3x3 pixel averaging smooth now, which can be done
by either the convolution kernel or mean.  

I am still trying the local adaptive thresholding using the methods
suggested.

3x3 averaging can be performed through Process -> Filter -> Mean.

Some sort of "adaptive thresholding" can be performed with the plug-in
'No-threshold' histogram-based image segmentation available at:
www.univ-reims.fr/INSERM514/ImageJ

but some adaptation will be necessary to make it work on stacks.
