Some of my fellow MATLAB Central bloggers have already talked about the MATLAB R2012a release. Usually, I like to scan the release notes and pick out just a few things that particularly... read more >>

Today's post is part of an ongoing tutorial series on digital image processing using MATLAB. I'm covering topics in roughly the order used in the book Digital Image Processing Using... read more >>

Blog reader Mike posed the following question recently: If you have a bunch of point locations (for example, object centroids), how you make a binary image containing just those ... read more >>

In this post in the Exploring shortest paths series, I make things a little more complicated (and interesting) by adding constraints to the shortest path problem. Last time, I showed this... read more >>

In my previous posts on Exploring shortest paths (November 1, November 26, and December 3), I have noted several times that there isn't a unique shortest path (in general) between one object and... read more >>

In part 2 of Exploring shortest paths, I noted a problem with using the 'quasi-euclidean' distance transform to find the shortest paths between two objects in a binary image.... read more >>

Earlier this month I started exploring the question of computing the shortest path from one object in a binary image to another. I described the following basic algorithm: ... read more >>

Today I want to tell a little image processing algorithm story related to my post last week about the new bwconvhull function in the Image Processing Toolbox. The developer (Brendan)... read more >>

I've been intending to mention a new function bwconvhull that was introduced in the Image Processing Toolbox last spring in the R2011a release. Now that R2011b is out, I figure I better... read more >>
