# 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... 続きを読む >>

# 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... 続きを読む >>

# Small-Peak Suppression with the H-Maxima Transform3

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... 続きを読む >>

# 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.... 続きを読む >>

# Use less meshgrid and repmat2

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... 続きを読む >>

# 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... 続きを読む >>

# NaN Sightings2

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... 続きを読む >>

# How to Use a Custom Interpolation Kernel with imresize2

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... 続きを読む >>

# How to Run Blog Post Code in Your Browser

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... 続きを読む >>

# Plotting a* and b* colors11

Today's blog post comes from planning one topic, but then taking a sharp left turn and doing something else completely. I was thinking about writing something related to meshgrid, and so I was... 続きを読む >>
