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... read more >>
I'd like to invite everyone to check out the new Deep Learning blog that just launched today on MATLAB Central. I happen to know the author, and he's an OK... read more >>
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... read more >>
Today I want to tell you how and why I made these images: After the MATLAB R2014b release, I wrote several blog posts (Part 1, Part 2, Part 3, and Part 4) about the new default colormap, parula, that... read more >>
I saw a presentation last month that mentioned a user request to have the ability to customize regionprops. That is, a user wanted to be able to add their own measurement to regionprops.Today, I'll... read more >>
A MATLAB user recently contacted tech support with a question about the output of fft2. The user had a function, q(x,y), evaluated on an (x,y) grid. The grid evaluation produced a matrix that the... read more >>
A few weeks ago, I wrote about a solver algorithm for the Eight Queens Problem. The post included diagrams like this one. Today I want to show you how I made that diagram in MATLAB. First, let's talk... read more >>
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... read more >>
