R2022a
It's March, and you know what that means --- that's right, the "a" release is here!On most work days, I use several different MATLAB versions, mostly development builds, on 2-3 different computers.... 더 읽어보기 >>
A Short Game of Life 5
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... 더 읽어보기 >>
Visualizing out-of-gamut colors in a Lab curve 7
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... 더 읽어보기 >>
Peaks, Peak Filtering, and Gray-Scale Weighted Centroids 5
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... 더 읽어보기 >>
Small-Peak Suppression with the H-Maxima Transform 3
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... 더 읽어보기 >>
Local maxima, regional maxima, and the function imregionalmax
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.... 더 읽어보기 >>
Use less meshgrid and repmat 2
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... 더 읽어보기 >>
Use imbinarize to Threshold Gray-Scale Images
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... 더 읽어보기 >>
NaN Sightings 2
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... 더 읽어보기 >>
