Brett: You certainly an impressive collection of useful demos, tutorials, and utilities. I can't say that I've used any so far but I may have a need later this year for clusterImg. I've just recommended it to someone in Answers: http://www.mathworks.com/matlabcentral/answers/90645#comment_175059 And I've often recommended your deleteOutlier submission. I tend to hang out at Answers more these days because of the ability to edit my posts and to attach files and images, neither of which I can do in the Newsgroup, so I only wander over to the newsgroup about once a week or so.
expandAxes also looks like something I might be able to use, and I'll have to experiment around with SegmentTool when I get a chance.
I also have a collection of about 130 general purpose demos, tutorials, and utilities that I've written, many in response to newsgroup or Answers postings. Some day I'll post them all in something like a "grab bag of image processing demos" because I think they could help a lot of people. One advantage that they have is that they are code that runs, whereas code given in the help or on Steve's blogs is broken up with a lot of helpful explanation. I do have some explanation in comments in my code but of course it's not extensive like you could give in a blog or the help documentation, but then those helpful explanations make running the code a tedious multi-step process of pasting multiple different sections of code. It might be nice if when you give code in a blog or the help that you can simply copy and paste without having to comment out a bunch of non-code explanations in between the code that runs.
As you know I do usability sessions and Reeve knows how to get on touch with me. I would definitely be very excited if you or the Mathworks could develop the 3D color gamut visualizer application and would love to test that. I was just showing off the one in ImageJ to a color short course I was teaching in Venezuela 4 days ago. We've also had discussions with your imaging team and our imaging team and perhaps it's time to do that again. And every time I come up with a new idea, I add it to my wish list and send it off to Jeff and Mara. It's great that your team is so responsive! Image Analyst.
