Dear all,

I am new in this feild, but I still know something about PSNR.
It is the way to compare the differences between 2 sources(e.g. images)

It can found with known MSE:

	constant
PSNR = ------------
	sqrt(MSE)

I don't really remember the constant. It can be 225, I think.
By the way, what is LP norm? I use MSE and MAE in image compression, and have
no about LP norm.

Ting
