Destructive doubts

I’m stuck ! I’ve been wanting to add color to the video-chat test app, but I can’t seem to focus and decide how to do it.
I want to do something clever. I’m already compressing the luminance (gray level image) at relatively high quality. To compress the remaining two color components without utilizing the similarities with the luminance it would be a crime. At the same time, it’s not easy to just write code for an algorithm without even a source of inspiration.
If I don’t come up with something clever, I’m bound to force the data size to sensibly grow, or have poor quality. This doesn’t particularly make me happy. On the other hand, black and white images really suck 8)
The truth is that I should sit down and start making experiments. Compression is all about statistics and statistics is all about inspecting data. In all honesty, I’m not sure how chrominance components are distribuited, therefore I can’t really come up with something good.

Doubt is probably the number one killer for productivity !

    Doubts are good. I get into that state often, when I intuitively feel that I dont have enough data to advance.

    But after a while an idea formalizes in my mind and I can proceed with confidence.

    The idea formalizes because you get more data to advance or just out of the blue ?
    Once I read that, apparently, sleep helps solve problems at a subconscious level.
    What I remember about sleep is that sometimes I try to solve problems in that state, but I feel stupid and powerless.
    Perhaps because my problems aren’t usually purely mathematical ones. I mean a quantum physicist can take pen and paper and go on for years. While if I’m without a PC I can’t do much.

    You get more data.

    But some of the data comes just from thinking about a problem and getting a more clear picture of what you are tying to do.

    Subconsciously you might be remembering some similar problems that you came across in the past, etc…

    Sad Mr. Kaz … sad! You need good data? You’ve got a camera go take some photos! Try different light settings, etc. Inspire yourself! (^-^)

    I think if you take some time and just go around and take pictures that you can use, the idea will come to you a lot more easier. 8P

    Man.. you are not in Tokyo !
    Come here and go outside trying to take a few pictures. They will all be blurred as you shift towards some sexily dressed chick. This city is a challenge on itself. The most productive avenue is to stay home !
    Any man living in Tokyo with hormones to speak with, is better off segregated in his apt.. as far as productivity goes.

    Ok. What kind of pictures do you need? I’ll remove your excuse for not having decent data. 8P I need to go out and take pictures anyway. I generally prefer taking pictures with no human beings in it though. 8P
