General question about JPEG Quality

Recommended Posts


I'm sorry if this doesn't really fit here, but could you help me with a small question?

I've got the task to write a small text about JPEG, and there's this quality slider when you're saving a JPEG. Now there's a question I can't answer yet: where does the JPEG compression algorithm include that quality parameter?

I'm not sure, does it make the compressed blocks larger or does it influence the quantization matrix?

Would be great if you could help me until tomorrow evening. :D

Chris :)

The Doctor: There was a goblin, or a trickster, or a warrior... A nameless, terrible thing, soaked in the blood of a billion galaxies. The most feared being in all the cosmos. And nothing could stop it, or hold it, or reason with it. One day it would just drop out of the sky and tear down your world.
Amy: But how did it end up in there?
The Doctor: You know fairy tales. A good wizard tricked it.
River Song: I hate good wizards in fairy tales; they always turn out to be him.

What I found: http://www.ams.org/featurecolumn/archiv ... ssion.html (via English Wikipedia article talk page). I think that's ok for my work...

Funny enough, I found it by simply trying out the different Wikipedia articles and their talkpages. Needed 15 minutes to find it, after searching the web with Google for about 6 weeks now. Google isn't omnipresent so far. :lol:

Thanks anyways,

Chris :)
