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 >>

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 >>

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 >>

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 >>

The March 2009 issue of IEEE Signal Processing Magazine landed in my mailbox last week. It contains a special section on digital forensics. The special section is jam-packed with image processing,... 続きを読む >>

It's not always easy to find the right level of documentation for a particular function, as I was reminded by this recent sci.image.processing post slamming the doc for imregionalmax and... 続きを読む >>

One of the changes we made to MATLAB in R2009a was to improve the way imread handles multipage TIFF files. (A multipage TIFF file is one that contains multiple images. I'm not sure, but I think... 続きを読む >>

Earlier this week I posted an update to my MTEST unit test framework on the File Exchange. I wasn't completely happy with my assertion function for comparing floating-point numbers using a... 続きを読む >>

MATLAB R2009a was released earlier this month. There are several things in this release, both in MATLAB and in the Image Processing Toolbox, that I plan to write about during the next couple of... 続きを読む >>

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 >>
