Today I'm introducing a series on computing the location of the US continental divide. (I was inspired to tackle this topic by Brian Hayes' blog post on the divide; thanks very much to... 더 읽어보기 >>

I recently heard a MathWorks application engineer (hi, Brett!) say that a short little paragraph in the regionprops documentation was very "powerful." Here it is: The function ismember... 더 읽어보기 >>

Last August I posted an example showing how to display patch objects transparently over an image. I meant to follow that up with another post showing a couple of ways to display one image... 더 읽어보기 >>

I've seen several situations recently in which a user couldn't figure out how to get their data into MATLAB, and it turned out that the data was in a form that could be handled by the... 더 읽어보기 >>

Today I want to know if you've heard of an operation sometimes called the feature transform, and whether you've had a particular application for it. But first, greetings to those who... 더 읽어보기 >>

Last month I wrote about a color gamut mapping course that I took at the Color Imaging Conference in Portland, Oregon. I showed a couple of images in that post, in which I promised to... 더 읽어보기 >>

This post is another in my series on morphological dilation and erosion algorithms. One of the algorithm techniques used by imdilate and imerode is binary image bit packing. In bit packing,... 더 읽어보기 >>

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... 더 읽어보기 >>

In my previous post on dilation algorithms I discussed structuring element decomposition. We looked at the decomposition of structuring elements with rectangular domains. Today I want to... 더 읽어보기 >>

Transparent graphics objects can be used effectively to visualize image processing concepts. Two particularly useful techniques are: Highlighting image... 더 읽어보기 >>
