I played with them for a bit (not very carefully), and here is what I would suggest.
1. Reduce the noise in the images (using something like filters->enhance->despeckle) 2. Try to sharpen it a little because this usually ends up slightly blurred (using something like filters->enhance->unsharp mask) You need to play with steps 1 and 2 until you get something you're happy with. 3. I then tried to convert the image to a vector format, and I used autotrace for this. Here [ http://emphaticallystatic.org/blogimages/eldstripador.png ] is a sample of a zoomed section showing the sorts of results you can achieve. You can do much better if you take a bit more time coming up with the right values for the numerous settings and choices for denoising and sharpening.
