# Double Thresholding

Back in June, my answer to a question on MATLAB Answers used a technique called double thresholding, also known as hysteresis thresholding. Although the question raised was a 1-D problem, I wanted to... read more >>

# Code Trace for MATLAB9

Today's post departs from image processing, my usual subject. Instead, I want to tell you about something that I just put up on GitHub and the MATLAB File Exchange.Earlier this year, I was debugging... read more >>

# Puzzle Pieces and Polyshapes

# How to use IMSPLIT to split a color image into component images2

Today I want to show you a handy little function, imsplit, for splitting color images into their components.Also, for no reason other than WOW, I want to show one of the images just released by the... read more >>

# Find all the highest pixel values using ismember2

Today's post shows how to use ismember to conveniently locate all of the highest pixel values in an image. For example, in the following Hough transform image, what are the 20 highest values, and... read more >>

# More experiments with sRGB gamut boundary in L*a*b* space3

I'm still playing around with RGB gamut calculations in $L^* a^* b^*$ space. (See my last post on this topic, "Visualizing out-of-gamut colors in a Lab curve.") Today's post features some new... read more >>

# Puzzles About GIF DelayTime

[TLDR: To create a fast GIF animation using imwrite, use a DelayTime of 0.02 instead of 0.]In my 28-Feb-2022 post, I showed some code that created an animated GIF file using a DelayTime of 0.im =... read more >>

# Loren Shure and the Art (and History) of MATLAB1

The one and only Loren Shure has just announced her retirement from MathWorks. I met Loren in early 1993 at the International Conference on Acoustics, Speech, and Signal Processing in... read more >>

# 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.... read more >>

# A Short Game of Life5

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 >>
