Ok, so here you could try replace 'nearest' by 'bilinear' or 'bicubic'.
I believe those are the most common choices for image resampling
(because when you plot an image and then save it, there is a resampling
involved).
(http://matplotlib.org/api/pyplot_api.html#matplotlib.pyplot.imshow for
the other options)

Of course, it's also worth playing the dpi argument of savefig, as
suggested by Eric.

Pierre
