Why not use octave for image processing? It can be run from within Sage, and its image processing toolbox is very mature and functional. >From what I've seen of PIL, its functionality is outstripped by octave. -Alasdair On Jan 10, 1:11 am, lfmartins wrote: > I'm trying to do image processing i

Thanks, I will try it. What I want do is pretty simple, simply open an image, add noise to it and try error-correcting codes. I was able to do it easily with PIL. I am actually thinking of what to use for bit operations, etc. My plan is to simply use Numpy, but octave may be an alternative. On S

Sure, once I actually write them. So far I just experimented with the stuff. On Sat, Jan 10, 2009 at 12:25 PM, David Joyner wrote: > > On Sat, Jan 10, 2009 at 11:54 AM, Luiz Felipe Martins > wrote: >> >> Thanks, I will try it. >> >> What I want do is pretty simple, simply open an image, add noi

Yes, that's octave. As far as I know it only uses ImageMagick for reading and writing files, and it may well be able to read and write PBM/PGM/PPM natively. But if you're using linux, then you'll have ImageMagick available. I don't know if there's a windows port. -Alasdair On Jan 11, 12:20 am
