Steve on Image Processing

Upslope area code is now available

After my last upslope area post, I decided that I had enough of the algorithm details worked out to produce a set of working M-files. Although I have a few more posts to go, I've already uploaded the M-files to the MATLAB Central File Exchange. If you've been following this topic with interest, then I suggest that you download the files and give them a try. Each function in the set has one or more examples in the M-file help. You might also want to try Wolfgang's code, which is also on the File Exchange.

If you downloaded my files since I originally posted them last week, you might want to download them again, because I modified upslope_area.m based on early feedback. See the Readme.txt file for details.

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).
