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... 更多内容 >>

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... 更多内容 >>

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... 更多内容 >>

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... 更多内容 >>

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... 更多内容 >>

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... 更多内容 >>

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... 更多内容 >>

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... 更多内容 >>

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... 更多内容 >>

At MathWorks, we almost never talk in detail about product features before they are released. That's why this week's Art of MATLAB blog caught my eye. Guest blogger Dave Bergstein describes in some detail how we expect support for string arrays to evolve in the future. If you do a lot of data analysis or text processing in MATLAB, it is worth your while to take a look at Dave's post.... 更多内容 >>
