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

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... 더 읽어보기 >>

# 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... 더 읽어보기 >>

# 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... 더 읽어보기 >>

[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 =... 더 읽어보기 >>

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 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... 더 읽어보기 >>

# Visualizing out-of-gamut colors in a Lab curve7

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 Centroids5

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 >>
