Wrapping up the analysis of Cody solutions 3
Today I'm wrapping up my analysis of the results of my Cody problem on eliminating unnecessary polygon vertices.... 更多内容 >>
Visualizing the floating-point behavior of the point-on-line test 1
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,... 更多内容 >>
Cody problem solvers: simplify a polygon
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... 更多内容 >>
A Cody problem: simplify a polygon 7
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... 更多内容 >>
Walking along a path 5
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.... 更多内容 >>
How im2html works
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 =... 更多内容 >>
New blog – Cleve’s Corner! 2
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... 更多内容 >>
Making an HTML table of pixel values with colored cells 3
Today's post shows 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 =... 更多内容 >>
Shuffling label colors 3
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... 更多内容 >>
