Dilation with linear structuring elements 13

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... read more >>

Another timeit update

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... read more >>

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... read more >>

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,... read more >>

Online resources: psychophysics, colour engineering

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... read more >>

A structuring element decomposition “gotcha” 12

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 ... read more >>

Color Gamut Mapping 6

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... read more >>

ICC DevCon 2008

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... read more >>

Image processing code on the File Exchange 4

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... read more >>

Update to timeit

On Leap Day, 2008, I posted about how to time code in MATLAB, and I gave a link to a timing utility function called timeit that I submitted to the MATLAB Central File Exchange. If you use... read more >>
