In this post, I'll explore how imshowpair and imfuse work.Reason: I was curious.Last month, I wrote about registering several hand-held photographs together. In that post, I used imshowpair several... read more >>

# Registering Hand-Held Pictures

The typical modern French* horn, pictured below, has about 23 total feet of tubing. At the beginning and the end, the tubing is conical. In the middle, the tubing is cylindrical.Depending on which... read more >>

# Transforming a color image to a weighted adjacency matrix

A question on MATLAB Answers caught my eye earlier today. Borys has this pseudocolor image of a weighted adjacency matrix: And he has this image of the color scale: Borys wants to know how to compute... read more >>

# How to Compute Perceptual Color Difference3

I wrote previously about the new colorChecker, which can detect X-Rite test charts in the R2020b release. Another area of new color-related functionality is computing perceptual color differences.... read more >>

# Rediscovering Cody

Lately, I've been spending more time on MATLAB Central, and I'd like to encourage you to try out some of the resources there, if you haven't already.Have you heard of Cody? It is an addictive MATLAB... read more >>

# How to Detect an X-Rite® ColorChecker® Chart1

When I saw this picture, I was really tempted to take it into the local garden nursery and ask them how to keep color checker charts out of my rhododendrons. No, no, this post is not really about... read more >>

# Making Color Spectrum Plots – Part 35

Recently, I've been explaining how I made this plot, which is from DIPUM3E (Digital Image Processing Using MATLAB, 3rd ed.): In my July 20 post, I showed one way to compute the spectral colors to... read more >>
