Locating the US continental divide, part 1 – Introduction 23

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... 続きを読む >>

Using ismember with the output of regionprops 60

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... 続きを読む >>

Image overlay using transparency 61

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... 続きを読む >>

Consider multibandread for reading your data 49

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... 続きを読む >>

Have you heard of the “feature transform”? 13

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... 続きを読む >>

Soft proofing example

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... 続きを読む >>

Packed dilation and erosion

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,... 続きを読む >>

Dilation algorithms – performance of decomposed strels

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... 続きを読む >>

Dilation algorithms—decomposing more shapes 2

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... 続きを読む >>

Image visualization using transparency 17

Transparent graphics objects can be used effectively to visualize image processing concepts. Two particularly useful techniques are: Highlighting image... 続きを読む >>
