# Feret Diameters and Antipodal Vertices3

Last time, I wrote about finding the maximum Feret diameter for an object in a binary image, ending up with this figure:... read more >>

# Feret Diameter: Introduction8

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 the object to be measured inside the jaws of a caliper, with the caliper oriented at a specified... read more >>

# Customizing REGIONPROPS With Your Own Measurements12

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.... read more >>

# Frequency Samples for the Output of FFT21

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 user passed to fft2. The user's question: what are the spatial frequencies associated with the elements... read more >>

# Chessboards, Implicit Expansion, REPELEM, and Unicode Chess Queens1

A few weeks ago, I wrote about a solver algorithm for the Eight Queens Problem. The post included diagrams like this one.... read more >>

# The Eight Queens Problem – Generating All Solutions

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 queen. Here is one solution.... read more >>

# The Future of String Arrays in MATLAB

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.... read more >>
