Recently, I've been explaining how I made this plot, which is from DIPUM3E (Digital Image Processing Using MATLAB, 3rd ed.): In my July 20 post, I showed one way to compute the spectral colors to... 続きを読む >>

It was a while ago now, but on April 27 I started explaining how I made this plot, which is from DIPUM3E (Digital Image Processing Using MATLAB, 3rd ed.):... 続きを読む >>

Does this line of code make you raise your eyebrows in puzzlement?c = sum(A,[1 2]) If so, you are likely an experienced MATLAB user who does not make a habit of carefully studying the release notes,... 続きを読む >>

Here's an interesting snippet I learned while working on today's blog post: Mathematician Jacob Bernoulli asked for a logarithmic spiral to be engraved on his tombstone. Here's an example of a such a... 続きを読む >>

Today I want to finish up my long-running discussion of Feret diameters. (Previous posts: 29-Sep-2017, 24-Oct-2017, 20-Feb-2018, and 16-Mar-2018.) Recall that the Feret diameter measures the... 続きを読む >>

Last time, I wrote about finding the maximum Feret diameter for an object in a binary image, ending up with this figure: I had computed the convex hull of all the pixel corners, and then I computed... 続きを読む >>

This is the first of a few blog posts about object measurements based on a concept called the Feret diameter, sometimes called the caliper diameter. The diagram below illustrates the concept. Place... 続きを読む >>

Before I dive into today's topic, I want to invite you to come back to the MATLAB Central Blogs page in a couple of weeks. Look for something new to appear related to deep learning.Earlier today, I... 続きを読む >>

On April 20, I wrote about an algorithm for solving the Eight Queens Problem. In this problem, the task is to place eight queens on a chessboard so that none of the queens is attacking any other... 続きを読む >>

Until about two weeks ago, I had given absolutely no thought to the possibility of a relationship between MATLAB and Pokémon Go, this summer's worldwide mobile gaming phenomenon. But then I... 続きを読む >>
