As I mentioned in an earlier post, Adobe Photoshop CS3 Extended provides some MATLAB integration features. If you're interested, here are a couple of links I've seen that might be useful: ... 続きを読む >>

Loren wrote about the 2007 MATLAB World Tour in her Art of MATLAB blog recently. Several other MathWorks developers also attended some of the events. One message that they brought back... 続きを読む >>

I've about run out of things to say for now about connected component labeling algorithms. ("Hurray!" shouts the audience.) For reference, here's a summary of all the posts in the... 続きを読む >>

I described in my previous connected component labeling post the algorithm used by bwlabeln. This time I'll talk about the variation used by bwlabel. This variation uses run-length encoding as... 続きを読む >>

[NOTE: After I originally wrote this post about handling plateaus, I discovered problems with the method, so I am no longer using it. I revisited the plateau issue in a later post. -SE] ... 続きを読む >>

The MathWorks announced yesterday the availability of MATLAB® & Simulink® Student Version R2007a. Readers of this blog might be interested to know that several additional... 続きを読む >>

In my previous upslope area post, I showed this graphic of pixel flow around North Pond in Milford, Massachusetts: Notice that pixels in the pond have no arrows. In fact, the... 続きを読む >>

In this part of the connected component labeling series, I'll finally get to one of the algorithms actually used in the Image Processing Toolbox. It's based on a technique called ... 続きを読む >>

Early in my graduate school days, I once spent a couple of days poring over code listings trying to find the cause of a mysterious bug. Eventually I discovered that the code had a "1" somewhere it... 続きを読む >>

In Part 2 of the upslope area series, I showed an M-file, pixelFlow, that could calculate a pixel's flow direction and magnitude according to the D-infinity method of Tarboton. Let's... 続きを読む >>
