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... 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 >>
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... 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 >>
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,... 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 >>
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... 続きを読む >>
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.... 続きを読む >>
