I've written previously about defining a spatial transform as a function, (x,y) = T{(u,v)}, that maps points from one space (input space) to another (output space). Given such a function, how do... 更多内容 >>

A MATLAB user asked me how to determine which image pixels had local maxima that weren't unique. My answer involves a creative use of ordfilt2. Let's review first the concept... 更多内容 >>

This week I wrote the last in a series of postings that discussed how MATLAB associates matrix values with specific screen pixel colors. The series talked about the two fundamental image display... 更多内容 >>

In my previous postings on this topic, I've discussed the basic image display models in MATLAB - truecolor and indexed. The Image Processing Toolbox has conventions for two additional image... 更多内容 >>

The MathWorks does not normally preview unreleased features, but I thought this might be a good time to make an exception. We are very excited about a set of new performance optimizations we are... 更多内容 >>
