This week I came across some files I wrote about 16 years ago to compute Hilbert curves. A Hilbert curve is a type of fractal curve; here is a sample: I can't... 続きを読む >>

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

Blog reader Asadullah posted the following question last week on my old post about batch processing: I am trying to process some images by following the MATLAB demo. After getting the... 続きを読む >>

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. ... 続きを読む >>

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... 続きを読む >>

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... 続きを読む >>

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.... 続きを読む >>

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: ... 続きを読む >>

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 ... 続きを読む >>
