Today I'm starting an regular, occasional series with tutorial material on digital image processing using MATLAB. I'm going
to look at topics in roughly the order used in the book Digital Image Processing Using MATLAB, Gatesmark Publishing, 2009, [...]

I just realized that it's been more than three years since I explained the way I handle comments on this blog. It's probably time for an update as many readers are new since then.
I moderate comments on this blog. That is, when you add a comment to the post, it doesn't appear on the blog [...]

Much of the information I posted in this blog years ago is still useful today. Image processing theory hasn't been completely
overturned since then, and I'm still talking about MATLAB after all. For the benefit of readers who have joined the party

Today I want to take the test pattern I created last time and subject it to a variety of frequency-based filters.
In this post I'll be using a variety of frequency design and frequency-response visualization tools in MATLAB, Signal Processing
Toolbox, and [...]

Earlier today I told you that I was feeling a little dense because I couldn't figure out the right parameters to use in the tanh term of
this test pattern:
(This is equation 10.63 in Practical Handbook on [...]

Last week I talked about the so-called Jähne test pattern and how I found a description of it in Practical Handbook on Image Processing for Scientific Applications, by Bernd Jähne, CRC Press, 1997. This equation was given in the book:
And here's a [...]

The July 2011 issue of MATLAB Digest is out, and an article by Martin Knapp-Cordes and Bill McKeeman caught my eye. It describes improvements to the MATLAB tic and toc functions. It also describes some general principles and specific techniques associated with trying to measure elapsed time in standard seconds on a computer. It turns [...]
