Image processing code on the File Exchange

MATLAB Central, including the MATLAB Central File Exchange, received a significant upgrade last month. With the File Exchange, you have many more ways to find and get notified about files that may interest you. Any search view can be turned into an RSS subscription feed, or into an automatic e-mail notification.

I just added the following searches to my set of RSS feed subscriptions:

Have you found image processing submissions on the File Exchange that you think are especially good? Please share your thoughts with the rest of us; leave a comment.

    hi,
    I need an mfile that detects colors!
    it should say,the color is white,black,brown,blue,…

    Simin—Try John D’Errico’s File Exchange contribution for color name identification.

    Hi Steve,

    I would like to create a binary mask based on a region I draw on top of an image. I know that in R2008b the IP toolbox has functions like createMask to do this. But I am using R2007a. Is it possible to pull this off in 2007a? Thanks.

    Adrian—Sure. That capability has been in the toolbox for 15 years. See functions like roipoly, poly2mask, and getline.

Wrap code fragments inside <pre> tags, like this:

<pre class="code">
a = magic(3);
sum(a)
</pre>

If you have a "<" character in your code, either follow it with a space or replace it with "&lt;" (including the semicolon).
