Hi
I should have been a bit more precise: I'm into astronomy. I'm mostly
interested in noise reduction / signal enhancement and therefore apply
different filters to the image. Some of this operations, like for
example the MedianFilter[] function, take a lot of computation time.

Hi Sarah - what kind of image processing are you considering? What types of
operations are you finding slow in Mathematica?

Subject: [Jchat] J for Image Processing
Hi
I'm new to J (and virtually to programming in general). I have just finished
reading the J Primer. For my PHD I need to do some image processing. I was
wondering whether J was a good choice for image processing, since the
language works so fine with arrays. At the moment, I'm mostly using Wolfram
Mathematica, which I like a lot, but it is also very slow.
Is J fast? Does there already exist a library for image processing tasks?
Any help is appreciated!
Sarah
