Plotting a* and b* colors 11

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... 더 읽어보기 >>

FFT Spectral Leakage 10

A MATLAB user recently contacted MathWorks tech support to ask why the output of fft did not meet their expectations, and tech support asked the MATLAB Math Team for assistance. Fellow Georgia Tech... 더 읽어보기 >>

How imshowpair and imfuse work 1

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... 더 읽어보기 >>

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... 더 읽어보기 >>

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... 더 읽어보기 >>

How to Compute Perceptual Color Difference 3

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.... 더 읽어보기 >>
