I have written here, as well as in Digital Image Processing Using MATLAB, about using image processing operations to implement Conway's Game of Life. MATLAB creator Cleve Moler has written about... read more >>

I was looking today at an old post, "A Lab-based uniform color scale" (09-May-2006). I wanted to provide an update to illustrate that it is easier to convert from Lab to RGB colors now than it was... read more >>

Today, I'm continuing my recent theme of thinking about peak-finding in images. When I wrote the first one (19-Aug-2021), I didn't realize it was going to turn into a series. This might be the last... read more >>

Last time, I introduced the idea of a regional maximum. Today, I want to add a concept that makes the regional maximum more useful: suppressing very small local maxima, possibly present only because... read more >>

A recent algorithm discussion on the Image Processing Toolbox development team reminded me of something I originally wanted to do a long time ago: explain imregionalmax and some related operations.... read more >>

The functions meshgrid and repmat have a long and rich history in MATLAB. Today, I'll try to convince you to use them less.meshgridThe function meshgrid is typically used to take a vector of... read more >>

Today, I want to convince you to use imbinarize instead of im2bw.Background: I recently saw some data suggesting that many Image Processing Toolbox users are still using im2bw, an old function that... read more >>

Some of us at MathWorks like to share our "NaN sightings." Here is an example to show what I mean. This is a screenshot of the tuner/metronome app that I use when practicing music. One day, I was a... read more >>

Recently, I was talking with MathWorks writer Jessica Bernier about the reference page for the imresize function. Jessica pointed out that we don't have an example that shows how to use your own... read more >>

I have published more than 560 blog posts here since 2006, and I estimate that about 98% of them started out as MATLAB scripts.Recently, I've started writing my blog posts as live scripts. Live... read more >>
