Today's post is about this picture, which is from the paper "Classroom Examples of Robustness Problems in Geometric Computations," by L. Kettner, K. Mehlhorn, S. Pion, S. Schirra, and C. Yap,... 더 읽어보기 >>

A couple of weeks ago I posted about how one might want to simplify the output of bwboundaries in order to remove unneeded vertices in the output boundaries. That is, turn this polygon: into this... 더 읽어보기 >>

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... 더 읽어보기 >>

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.... 더 읽어보기 >>

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 =... 더 읽어보기 >>

All of us MathWorkers who hang out on MATLAB Central are very excited that MATLAB creator and MathWorks cofounder Cleve Moler has just become the latest MATLAB Central blogger.I think I first started... 더 읽어보기 >>

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... 더 읽어보기 >>

On my list of potential blog topics today I saw just this cryptic item labeled dftmtx. Hmm, the MATLAB dftmtx function. But have I written about this function before? I better double-check by... 더 읽어보기 >>
