SandmanThe article is about thermodynamics. The concepts and the mathematics and the concept of entropy apply to a number of topics including information processing which, in turn, includes image processing.

On this occasion, at least, Floyd most certainly knows what he is talking about.
Haha, no.Eric StevensEric StevensSandman
A problem seems to be that very few other people seem to.
Well, we all know that YOU rarely have the first clue about what you're talking about, so I have no problem understanding why you're here supporting ignorant Floyd.
Floyd's usage is strictly in accordance with http://en.wikipedia.org/wiki/Reversible_process_%28thermodynamics%29
Great input, if the topic had been about thermodynamics.
He never claimed that the JPG can be reversed. As I have already written, he said that the original image can be recovered after sharpening by HPS even after the image has been saved as a JPG.Eric StevensSandman
as it applies information theory. If you think there is no room for reversible processes in information theory see http://tinyurl.com/otp5pug
Why can't you read?
1. Floyd thinks that HPS + JPG compression can be reversed. It can not.
2. Floyd thinks that a non-destructive workflow is not a reversible process, it is.It's not a reversible process in the way that he used the term.
Just the plain facts.I'm afraid they are not as plain or as straightforward as you would like to have them. --
