There is also some good saliency map work done by Laurent Itti at USC, and most of his code is available on the net.  See here http://ilab.usc.edu/bu/ for his bottom up visual attention code in C++.  I would be nice to see this integrated with ACT-R.

ACT-R does not build a saliency map of the image for you. If this is what you're looking for, this might be of interest:
