Exploring shortest paths – wrapping up

For the past several weeks I've been writing about shortest-path problems in image processing: finding the shortest path between two points in an image, with and without constraints. ... read more >>

Exploring shortest paths – part 5 5

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 >>

Exploring shortest paths – part 4

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 >>

Exploring shortest paths – part 3 2

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 >>

Exploring shortest paths – part 2

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 >>

Exploring shortest paths – part 1 9

Blog reader Bogdan asked this question last week: I am trying to find the length and location of the shortest path between objects. It seems like some application of bwdist ... read more >>

Five years ago: May, June, and July 2006

Much of the information I posted in this blog years ago is still useful today. Image processing theory hasn't been completely overturned since then, and I'm still talking about MATLAB... read more >>

Binary image convex hull – algorithm notes 9

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 >>

Binary image convex hull 1

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 >>

Digital image processing using MATLAB: reading image files 1

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 >>
