Re: Image processing prototype software

The cost of MATLAB wasn't too much of an issue for me (I fall into that
class you mentioned of scientists working for large companies). The
two main complaints I have against MATLAB are (1) no user interface
suitable for interactively exploring and playing around with your image
(which limits what many people in my company can do with it since
they're not really programmers), and (2) it often takes dozens or
hundreds of lines of code to do what literally took 1 or two lines in
Optimas (a now defunct package that had a lot of higher level
functionality in it).

ImageJ has a fairly user friendly user interface, for as much as it
has, although it doesn't have much. It does have a large user
community and it seems like anything I want to do is not built in and I
have to go online looking for a user-written plugin that is similar to
what I want and that I can adapt to fit my needs. Often these are
things that I think should be already built in. (Disclaimer: I haven't
used ImageJ in the past 2 years -- because of that.)

MATLAB has a similar user community, which I've used more than the
ImageJ one, but it seems like there are a lot of macros submitted that
are half baked. There are some good ones out there but a lot of them
are simple or lame like a grad student worked on them for a few minutes
and thought it might be fun to upload it before it was thoroughly
generalized (made generic), tested, or documented (commented).

From what I've seen at symposia, MATLAB could be the most widely used.
I think that is because universities already have it to teach linear
algebra and they can just spend a few extra bucks to get the
ImageProcessing Toolbox so they go with that. Reduces the learning
time and cost as compared to getting a different package, even though
there might be other packages out there that are better in terms of
having higher level functionality. ImageJ might be the second most
widely used, or it might be the first - I don't know of any stats on
that.

I think ImageAnalyst is being too hard on matlab. I think it has most
of the features you mentioned. The problems he mentions are more than
made up by the speed with which you can get code working and the wide
availability of free code developed by users.

The main problem with matlab is that it is expensive. It's a tool for
professionals and most of their customers work at companies where the
cost is trivial compared with the wages they pay their engineers. They
do have low cost packages for students.
