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... 更多内容 >>

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... 更多内容 >>

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... 更多内容 >>

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... 更多内容 >>

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 ... 更多内容 >>
