A couple of weeks ago I asked if anyone could guess what this "equation" means on my office whiteboard: It's related to the color management approach standardized by the International... read more >>

[Guest blogger Jeff Mather, a developer on the Image and Geospatial team, is also an avid amateur photographer. He published this essay on his personal blog earlier this year and graciously allowed... read more >>

This is the final post in a series discussing the algorithm underlying Image Processing Toolbox functions poly2mask and roipoly. (See Part 1 and Part 2.) There are several desirable... read more >>

Every now and then, a visitor to my office will ask, "Hey, what does that equation on your whiteboard mean?" So how about it, dear readers? What does "B = PCS" mean? Post your... read more >>

Last week I posted a link to some bilateral filtering MATLAB code on the Web. A commenter quickly pointed out that there was also an implementation available on the MATLAB Central File... read more >>

Loren and I frequently use the MATLAB publish feature to create our blog posts. Back in October, we started using some JavaScript in our blogs so you could click on a link to get the original... read more >>

I'm familiar with two basic ways to determine whether a point is inside a polygon. The first is to compute the winding number, which is the number of times that a closed curve encircles the... read more >>

This looks interesting: Medical Image Processing: Bilateral Filtering in MATLAB. It includes MATLAB code.
By the way, we have been experiencing blog database problems in the last 12 hours or so. We... read more >>

This is the first of several blogs about the algorithm behind poly2mask and roipoly. poly2mask takes a set of polygon vertices and produces a binary mask image. The binary mask has 1s for... read more >>

We had a visitor from Harvard Medical School and Massachusetts General Hospital here at MathWorks headquarters in November. Alex Tyrrell is a postdoctoral fellow at the Edwin Steele Laboratory... read more >>
