20 Oct 2009 freehanddraw Draw smooth lines freehand on images or plots; return the handle and xy data of the line object. Author: Brett Shoelson

I had been using this with R2008b and discovered that it's still "broken" in R2009b, but thanks to Paul Groot's helpful comment, it's now working again. However, now that the Image Processing Toolbox has imfreehand(), maybe you could use that instead.

Ditto what us said.

20 Mar 2009 imdisp Display multiple images as a montage of subplots Author: Oliver Woodford

One note of warning. If you call this function from within your m-file code for your GUI, it will blow away everything on your GUI - it will not automatically pop up a new window. To avoid this, I simply put the lines
figure;
imdisp(montageCellArray, 'Border', [.01 .01]);
into my code. This will bring up a new blank figure (which will get replaced by the montage of images rather than my GUI.)

Secondly, I'd like to see the option of having the base file name as a caption on each image.

Third, it should do a better job of sizing the window. Mine pops up with the bottom edge under the Windows task bar, and tons of space on the right and left edge of the screen. Ideally there would be an option to size it to some fraction of the screen, such as 90% of the size in both x and y direction, or even fully maximized (no border).

Looking forward to the captions....

10 Jan 2009 fdep: a pedestrian function dependencies finder FDEP dissects ML files and iteratively looks for all user defined functions used during runtime Author: us

I just downloaded it and it looks very nice. However I'd like you to fix the bug where it's locating the wrong module. I have a main module and it calls 8 other modules, 7 of which are in the same folder as the main module. However, module #2 you list as being one of the same name that I happen to have in another folder. I'm not sure why you're seeing that one first - MATLAB doesn't, it sees and runs the proper one which is in the same module as the main module. For example, in folder1, I have m-files myFile and mySubFile1, mySubFile2, etc. But in folder2, there is also a mySubFile1 and this is the one that your program is finding instead of the mySubFile1 in folder1.

A few more suggestions on the list GUI:
1. Replace the [John D'] button with a scroll bar or two small buttons to increase and decrease the font size.
2. I'd also like to see tooltips on your 6 buttons (right off the bat, it's not obvious what some of them do).
3. I'd like it to start with a GUI rather than a 2-steps command line process.
4. The Image Processing Toolbox is incorrectly called "images" in the toolboxes listbox.
5. A longer and more descriptive name than the short and cryptic "fdep" would be nice. And what does "pedestrian" have to do with it? Is that word needed?

Here's what MATLAB reports for my toolboxes:
MATLAB Version 7.7 (R2008b)
Image Processing Toolbox Version 6.2 (R2008b)
MATLAB Builder NE Version 3.0 (R2008b)
MATLAB Compiler Version 4.9 (R2008b)
Signal Processing Toolbox Version 6.10 (R2008b)
ToolBox EXAMPLE_SCRIPTS Version 1.0.0

Just my 2 cents on a well done program.

29 Aug 2009 BlobsDemo Image Processing Tutorial to demonstrate the basic concepts to beginner users. Author: Image Analyst us

an excellent and exceptionally well commented image processing demo by a seasoned ML user and senior CSSM citizen...

a few changes i'd make:
- put it into a function
  -> no need for the bad CLEAR ALL...
- make the figure size smaller -and-
- put an ECHO ON/OFF at the beginning/end of the demo
  -> for users to be able to enjoy the comments during run-time...

just a few thoughts
