Hello, I am a lecturer/researcher for image processing (photogrammetry and remote sensing) and since three or four years I am increasingly, meanwhile almost exclusively, using J.
As my main interests are in understanding/explaining algorithms and developing new ones, I am not much of a library user - if there is a lack of it in J, it does not bother me too much. I put of lot of stuff together myself meanwhile, including a few tutorials. Of course some of the available packages for mathematics and statistics are highly relevant for image processing too. For visualisation I export my results into whatever is suitable. I am very enthusiastic about J and its cababilities for image processing. J can be quite fast if you avoid explicit looping through the lines and columns of the image. Currently I am working on a camera-projector system where one of the issues is to find correspondences between 768*1024 projector pixels and 3072*4608 camera pixels (in a picture of a scene illuminated by the projector) and I didn't feel any desire to go back to C yet. I would be interested being in touch with image processing J-ers, via the forum or offline.

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!
