Today's blog post was written by Spandan Tiwari, a developer on the Image Processing Toolbox team. Thanks, Spandan!... 続きを読む >>

Today I'm combining my blog post with a new problem submission on Cody. The problem is related to the function bwboundaries in the Image Processing Toolbox. This function traces the boundaries of... 続きを読む >>

Last month I was experimenting with an algorithm in which I needed to construct a set of equidistant steps along a path consisting of line segments. (I'll call this a polyline path, or polyline for short.) Today I want to show you how to construct such a path in MATLAB. Along the way I'll show you the function improfile and give you a pointer to a database of sample range images that I found.... 続きを読む >>

On June 2 I showed you how to make a table with image colors and pixels appear when you publish your MATLAB scripts to HTML using the publish function. The result looks like this:rgb =... 続きを読む >>

I've written often here about various computational and visualization techniques involving labeling connected components in binary images. Sometimes I use the function label2rgb to... 続きを読む >>

Last year I posted a few times about the "Jähne test pattern," something that readers then told me was called a zone plate. This is a radial sinusoid pattern with low frequency in... 続きを読む >>
