How can you measure the quality of an encoding by referring only to its
output? Surely this is meaningless. Frequently my encoded stuff shows
higher PSNR than the source itself.
Wouldn't (eg.) a solid black image have infinite PSNR?
Perhaps output PSNR / input PSNR would mean something (like electronic
noise figure) but I doubt even that . . .
Comments appreciated!
