I just heard that the 2nd edition of Digital Image Processing Using MATLAB just shipped from the printer! Hurray! Now I'm using the satellite view in Google Maps to see if I can find the... 続きを読む >>

My colleague Greg Wilson, creator of the course Software Carpentry, proposed a couple of programming problems as prerequisites for the course. The idea is that if you can solve the problems... 続きを読む >>

Today, in part 5 of my series on computing the US continental divide, we'll look at a technique called minima imposition. Previously we looked at data import and display, the watershed transform... 続きを読む >>

A few years ago we introduced the Image Tool for image viewing, navigation, pixel-value display, cropping, etc. Here's a screen shot: The window on the left is called the "Overview... 続きを読む >>

Welcome to part 4 of my series on computing the US continental divide. Previously we looked at data import and display, the watershed transform and label matrices, and different kinds of... 続きを読む >>

In the previous post in this series on computing the US continental divide, we used the watershed function to find catchment basins in a DEM (digital elevation model). The result was more than... 続きを読む >>

Some blog readers may know that I've been giving a presentation called "Take Control of Your Code" for a couple of years now, since the 2006 International Conference on Image Processing in Atlanta.... 続きを読む >>

This post is the second in my series on computing the location of the US continental divide. Today I'm going to look at the watershed transform, including how to compute and visualize it... 続きを読む >>

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 >>

For the past several releases, we have been incrementally making more of the computational routines in MATLAB multithreaded. (More recently, we've also started doing this in the Image... 続きを読む >>
