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 >>

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.):... read more >>

Today I'll show you one way to visualize the sRGB color gamut in L*a*b* space with assistance with a couple of new functions introduced last fall in the R2014b release. (I originally planned to post... read more >>

I'd like to welcome back my fellow MATLAB Central blogger Brett Shoelson for the last in a three-part series on extracting curve values from a plot. You can find Brett over at the File Exchange Pick of the Week blog, or you can check out his many File Exchange contributions. -Steve... read more >>

I'd like to welcome back guest blogger Spandan Tiwari for the second post in his two-part series on homomorphic filtering.Last time we looked at how to apply a simple homomorphic filter. Today we... read more >>

We looked at the decomposition of different structuring element shapes in my previous post on dilation algorithms. Today let's time some code to how decomposition makes a real difference in... read more >>

Last week I wrote about a possible modification to poly2mask that would estimate how much of each pixel is contained within a polygon. The idea was to use a regular 5-by-5 subgrid and ... read more >>

The Image Processing Toolbox function applycform can convert colors based on ICC profiles. ICC standards for the International Color Consortium, and an ICC profile typically contains... read more >>
