Monday December 6, 2010 (Week 16;dead week) - See Course Outline.
Today we had a special guest, Mark Shaw, who talked about color imaging. Mr. Shaw is an expert (Senior) Color Imaging R&D Engineer at Hewlett-Packard. You can find a copy of his slides here (pdf format).
Among other things, Mr. Shaw taught us that color perception is an "integration process" which varies depending on the person (esp. color blind individuals) and the conditions of the environment. He illustrated how our perception of color varies depending on the surroundings colors in an image, and how our perception of color varies depending on the conditions of the surrounding environment. He also pointed out that our visual system adapts to its surrounding, and that this adaptation influences our perception of color over time. Towards the end of the lecture, we saw a mathematical way to describe the perceived color in terms of the conditions of the environment.
Discussion
Any comments? Did you enjoy the talk?
- I really enjoyed it. I'm not really into this side of DSP applications but I've heard some of the terminology before. I guess I never really realized just how much goes into deciding what a color is - especially when Mark explained about how, in the old days, they had to literally get 30 people to decide on one approximation of one color. That's ridiculous!! I'm thinking about the amount of manpower and time that goes into that sort of thing and in today's world, time is money and companies don't have that kind of time! ~ksoong
