Today I want to show you how to use a linear system of 90,300 equations and 90,300 unknowns to get rid of a leaf.Earlier this month I told you how the function roifill was recently renamed to... 更多内容 >>

About a year ago, I wrote a blog post criticizing one of my functional designs from the 1990s, roifill. Now I have an update based on the R2015a release of Image Processing Toolbox.Let me show you an... 更多内容 >>

A question came into tech support a month or so ago regarding the documentation for imdilate. The question concerned an apparent discrepancy in the equations for binary and grayscale dilation. Here's... 更多内容 >>

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 >>

Earlier this month we shipped R2015a, the first of our two regularly scheduled annual releases. Typically, when there's a new release, I spend some time talking about features that interest me. The... 更多内容 >>

This afternoon my wife looked at me with an expression indicating she was convinced that I had finally gone completely and irrevocably crazy.I think it was because I was carrying from room to room a... 更多内容 >>

I just saw a great animation illustrating the Fourier series decomposition of a square wave. Check it out. The video includes two different animations, so be sure to watch it all the way through to... 更多内容 >>

I promised earlier to post about divergent colormaps. A divergent colormap is usually constructed by concatenating two colormaps together that have different color schemes.Here is an example of a... 更多内容 >>
