I wrote last week about new features in R2009a related to connected component labeling. There are two new functions, bwconncomp and labelmatrix, as well as additional syntaxes for an existing... read more >>

This is a "small world" story for a mid-summer Friday. Outside work, family, and book writing, I like to play a little tournament chess. I'm just your middle-of-the-pack club player trying... read more >>

I've always had a kind of amateur's fascination with computational geometry, and computational geometry problems do arise in image processing from time to time. I've had just enough experience to... read more >>

Last week I wrote about our desire to reduce the memory used by bwlabel. I also wrote about other issues we hoped to address: The... read more >>

One of the changes we made to the Image Processing Toolbox for R2009a was partially inspired by comments received on this blog. Specifically, several blog readers complained about the... read more >>

Sometimes readers will tell me they had a hard time reproducing results from one of my blog posts, so let me tell you the easiest way to do it. Almost all of my posts that show MATLAB examples have... read more >>

I would like to remind readers about how I handle comments on this blog. (Please note that each MATLAB Central blog author handles comments somewhat differently.) I moderate all comments,... read more >>

In January 2006, the first month of this blog, I wrote the following: "Section 5.11 of Digital Image Processing Using MATLAB covers spatial transformations. I'm interested in expanding this... read more >>

Today is the final post in my continental divide series. In earlier posts I have used the problem of computing the US continental divide as a vehicle for exploring data import, image... read more >>
