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... 続きを読む >>

It was a while ago now, but on April 27 I started explaining how I made this plot, which is from DIPUM3E (Digital Image Processing Using MATLAB, 3rd ed.):... 続きを読む >>

The new edition of Digital Image Processing Using MATLAB (DIPUM3E) contains a number of MATLAB functions related to color, color calculations, and color visualization. I wrote about functions for... 続きを読む >>

When working on the "Color Image Processing" chapter of DIPUM3E, I found myself often wanting to display square blocks (or swatches) of color, like this: Eventually, I wrote a function,... 続きを読む >>

Today I will show you how I plotted this treble clef symbol in MATLAB: My discovery and implementation process for doing this involved Unicode characters, SVG files, string processing, Bezier curves,... 続きを読む >>
