Cool. Thanks Josh. <crap explanation>
And to explain why we have HSV at all: Think about analog television. If you look at the V channel of an image by itself, it's the same image, just "black and white". So adding the H and S channels to an old black and white broadcast, you add colour. JPEG/MPEG uses HSV so that the H and S channels can be scaled down as our eyes aren't as sensitive to colour as they are luminance. Hence the options such as 4:1:1 and 4:2:2 when encoding. This is why you can sometimes see colour bleed on hard edges. Also, you get much better entropy when encoding these channels independently. </crap explanation> On Oct 26, 8:19 am, Joshua Marinacci <[email protected]> wrote: > For those of you who are interested in design and usability, I've > started my series on design fundamentals with an explanation of color. > I'd love to get your feedback. > > http://www.joshondesign.com/?p=54 > > - Josh --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "The Java Posse" group.
