I am a crazy person. Late last week I was chasing down some numerical precision questions I had about certain color-space computations. I found myself trying to determine, once and for all, what... 更多内容 >>

A customer contacted Tech Support recently to ask the following question about structuring elements and dilation:If I created a structuring element from the matrix [1 1; 1 1], then the origin of the... 更多内容 >>

A blog reader asked me recently how to visualize the ellipse-based measurements computed by regionprops. The reader wanted to superimpose the estimated ellipses on the image.To refresh your memory:... 更多内容 >>

The set of colors that can be represented using a particular color space is called the gamut. Some L*a*b* color values may be out of gamut when converted to RGB. You know that a converted RGB color... 更多内容 >>

Here's something cool to try ... I just downloaded the MATLAB Support Package for Apple iOS Sensors and the latest MATLAB Mobile app for my iPhone. So the first thing I did was throw and catch... 更多内容 >>

Some years ago we added the function typecast to MATLAB. I've been wanting to write about this useful little function ever since we significantly speeded it up in the R2014b release.The function... 更多内容 >>

[This post has been updated on 04-Sep–2015 to describe the use of Simulink in the flight control system design and implementation. I’d like to thank Jon Friedman for providing this... 更多内容 >>

Last week someone asked me how many people use the “Get the MATLAB code” link on my blog. Do you know what that is? Try it now. Go to my recent post, “Displaying a color gamut... 更多内容 >>
