R is not a very heavy duty image processing program,
but the pixmap library have some aplications to use .ppm .pgm as matrix
you can manipulate them in numeric processes.
I use R for some small image processing and it works fine for teaching
objectives. (Walsh transform, fft,
Low pass filter, High pass filters (Lapplace), etc)
with images not bigger that 768*768.
Hope will help.
