This month finishes a third year for me of blogging about image processing algorithms, working with images in MATLAB, and more. Topics this past year included: A series of tutorials... 続きを読む >>

For my series on dilation algorithms, I've followed my unfortunate custom of dragging a series out way too long. :-) So let's wrap it up with a mention of the last key algorithmic idea... 続きを読む >>

I just posted another timeit update to the MATLAB Central File Exchange. (See my original post on timeit for a detailed explanation of its purpose and use.) The new version has a few... 続きを読む >>

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 >>

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 >>

Here are two sources of useful MATLAB functions that readers might be interested in. First, an acquaintance at Apple Computer recently told me about the Psychtoolbox. He thought that any... 続きを読む >>

In my earlier posts about dilation and erosion algorithms, I wrote about exploiting structuring element decomposition for improving speed. Today I want to discuss a potential decomposition ... 続きを読む >>

After attending ICC DevCon 2008 last week in Portland, Oregon, I stayed for another day to take a couple of short courses at the Color Imaging Conference. One of the courses was Color... 続きを読む >>

I just returned from spending a few days in Portland, Oregon. Monday was ICC DevCon 2008. ICC is the International Color Consortium, an organization responsible for the color profile spec, known as... 続きを読む >>

MATLAB Central, including the MATLAB Central File Exchange, received a significant upgrade last month. With the File Exchange, you have many more ways to find and get notified about files that may... 続きを読む >>
