Matlab and Octave
Matlab is a software system for dealing with matrix calculations.
Since images can be seen as large matrices, it has some image and
signal processing capabilities built in, for example, a nice
Fourier transform (which is good, since the iff version does not seem to work).
It also has a lot of nice graphical capabilities, and can
be used for massaging and presenting data.
Basically you type "matlab" at the system and it comes up.
Advantages: lots of bells and whistles, very user friendly, nice graphics.
Disadvantages: Runs as an environment, which means you have to everything
from inside it, so interfacing can be tricky, though seems to
work ok once you figure out how.
A bit of a memory pig - it doesn't always clean up unused storage very well.
An alternative is to use something called
Octave, which has a lot of the functionality and comes with gnu, so we
have unlimited users.
There are a couple of manuals in the software lab, and a good online
help system.
