Steve on Image Processing

October 12th, 2007

Category and archive links

We recently changed the view when you click on a category in the sidebar on the right. I haven't used categories much, but the other bloggers (Loren on the Art of MATLAB, Doug's Pick of the Week, and Inside the MATLAB Desktop) have been.

The new view presents a much more concise summary of all the posts in the category. To take advantage of the new view, I've created two new categories: upslope area and spatial transforms. I'll probably add others later on.

There's also an "Archives" link on the sidebar. This view shows all of the blog's post titles, sorted by month.

Try these links on the MATLAB Central blogs. You might find some useful content that you missed.

    Hi Steve,

    Thanks for keeping up with this BLOG, it is really fun and has been helpful for me in my work. If I think of any interesting ideas for topics, I’ll email ‘em to you.

    Best to all of you guys at the MathWorks!
