How does the tonemap function in the Image Processing Toolbox product work?
Tone mapping, or tone reproduction, compresses the enormous amount of illumination data in a high dynamic range image to something more suitable for output on a medium that has a lower dynamic range. The recent discussion of my office image shows the results [...]

It’s Friday here at The Metrowest Homeopathic Imaging and File Rehabilitation Center, the day when I usually spend part of my time on 20% projects. [1] But I’ve basically been working on the results of my last such project full time, so perhaps it’s time to take a moment and look at the world [...]

Previously, I’ve posted about using non-English characters in programming and the basics of character set encoding. It appears that I need to keep adding to this theme of internationalization and Unicode.
In particular, the issue of collation — how to sort characters — came up in my UNIX Tools class. I knew that the [...]

Last week, Lisa and I visited the Copps Hill Burying Ground near the Old North Church in Boston’s North End. I had walked by it a few times before but never gone in because it is sooo close to the end of the Freedom Trail, and our guests are usually ready for the long [...]

I want to share my del.icio.us bookmarks with you. Some of my “statistically improbable” tags with many items include:

color
high-dynamic-range
formats
metadata
hdr
DICOM
maps
nukes
suburbia
photography
osx

So what’s this all about?
Thirteen years ago when I was new to the web, I made bookmarks for every interesting web page that I came across. (Search was in its infancy.) After a [...]

A bunch of us around the office were talking about the cool content aware image resizing algorithm that we saw on Doug’s blog.

The idea behind Shai Avidan and Ariel Shamir’s work is to find information-neutral “seams” in the image and fold or expand the image along those constantly shifting fault lines. Unlike traditional methods [...]

Friends, I’ve been wanting to tell you about this for a while, and now that the beta public version of MATLAB R2007b is out, I can finally post. This will be the first of a series of articles about high dynamic range imaging. Let’s start by looking at a picture:

This is my office. [...]

Clay Buchholz pitched a no-hitter tonight. It wasn’t perfect — he hit a batter and walked a few — but it was just his second major league baseball game. Ever. What a great game!
The game had so much drama and was wonderful to watch. Even Lisa was cheering for the kid, [...]
