Making Color Spectrum Plots – Part 3 5

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... 更多内容 >>

What is 0.01? 4

I was looking at these two numbers the other day:0.015764607523034235576460752303423488It turns out they are very close, differing only by about 5 parts in a quadrillion.A tech support... 更多内容 >>

Making Color Spectrum Plots – Part 2

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.):... 更多内容 >>

Making Color Spectrum Plots – Part 1

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... 更多内容 >>

Geometric Transformation of Points – Getting Started 3

I like to think of geometric transformations of images (stretching, shrinking, rotating, etc.) by starting with the geometric transformations of points. You could think of a geometric point... 更多内容 >>

How to Display Color Swatches 2

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,... 更多内容 >>

Digital Image Processing Using MATLAB, 3rd edition

The 3rd edition of Digital Image Processing Using MATLAB (DIPUM3E) has just been published, at long last. The new edition includes extensive new coverage of image transforms, spectral color models,... 更多内容 >>

Treble clefs, Unicode, SVG, strings, Bézier curves, kron, implicit expansion, and polyshape 6

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,... 更多内容 >>

How to Write Animated PNG (APNG) Files from MATLAB 3

Today, I'm writing about how to create animated PNG (APNG) files, such as this one: I first wrote about APNG files last February. An APNG file is a valid PNG image file that uses file metadata in a... 更多内容 >>

How to Go a Little Crazy with Graphics Titles 1

The title function is the third most commonly-used function in my 13 years of writing this blog, after imshow and imread. You have probably all used this function many times.... 更多内容 >>
