• Writing a file reader in MATLAB

    Updated: 2012-02-28 00:00:07
    I'd like to introduce guest blogger Jeff Mather. Jeff started his MathWorks career as an application support engineer. Then, very many moons ago, I hired Jeff as a software developer to work on image and scientific file formats. Jeff's now on the Image Processing Toolbox development team, but as you'll see he still thinks about [...]

  • Digital image processing using MATLAB: writing image files

    Updated: 2012-02-20 15:47:31
    Today's post is part of an ongoing tutorial series on digital image processing using MATLAB. I'm covering topics in roughly the order used in the book Digital Image Processing Using MATLAB. The MATLAB function imwrite writes image data to a variety of different formats including: reads image data from a variety of formats, including JPEG, [...]

  • Saturday morning fun with Cody

    Updated: 2012-02-11 15:35:05
    Early this morning my wife found me in the family room, typing away at my laptop. She glimpsed this diagram on my screen and asked if I was playing chess. "I'm doing MATLAB, Cody, and chess at the same time," I responded. She gave me the "I have a weird husband" look and left to [...]

  • New comment policy

    Updated: 2012-02-07 00:28:31
    I want to let readers know that I'm experimenting with a new comment policy. I started this blog at the beginning of 2006. At first, I left comments open and only filtered out obvious spam. Soon, though, I found that I couldn't handle the volume of comments. Also, most comments were off-topic, which I thought [...]

  • Jobs and such

    Updated: 2012-01-31 18:59:38
    Last week I happened to come across a summary I wrote after completing my first month at MathWorks. This was quite a while a go ... December 1993! I was hired to take over development of the Image Processing Toolbox, which had just shipped version 1.0. From the summary, I see that I spent a [...]

  • Generating Hilbert curves

    Updated: 2012-01-26 04:40:47
    This week I came across some files I wrote about 16 years ago to compute Hilbert curves. A Hilbert curve is a type of fractal curve; here is a sample: I can't remember why I was working on this. Possibly I was anticipating that 16 years in the future, during an unusually mild New England [...]

  • Five years ago: August, September, and October 2006

    Updated: 2012-01-13 20:50:33
    Much of the information I posted in this blog years ago is still useful today. Image processing theory hasn't been completely been overturned since then, and I'm still talking about MATLAB after all. For the benefit of readers who have joined the party more recently, I will occasionally recap the useful bits that I posted [...]
