Hello everyone. I'm working on a fairly large project at my company and have been looking for some guidance. I just happened to stumble on this forum when looking for help with Solaris, so I'm hoping that you all won't mind me bothering you with my questions. :)
Anyway, here goes. Is it... (8 Replies)

I am learning Solaris Zones and I have the following doubts:
1.Sun has developed both Zones concept as well as Virtual Box concept. To work in Solaris if zones method is there, what is the need for virtual box?
From my little knowledge, I feel virtual box and the whole root zone are same... (4 Replies)

pnmpsnr
pnmpsnr(1) General Commands Manual pnmpsnr(1)
NAME
pnmpsnr - compute the difference between two portable anymaps
SYNOPSIS
pnmpsnr [pnmfile1] [pnmfile2]
DESCRIPTION
Reads two PBM, PGM, or PPM files, or PAM equivalents, as input. Prints the peak signal-to-noise ratio (PSNR) difference between the two
images. This metric is typically used in image compression papers to rate the distortion between original and decoded image.
If the inputs are PBM or PGM, pnmpsnr prints the PSNR of the luminance only. Otherwise, it prints the separate PSNRs of the luminance, and
chrominance (Cb and Cr) components of the colors.
The PSNR of a given component is the ratio of the mean square difference of the component for the two images to the maximum mean square
difference that can exist betwee any two images. It is expressed as a decibel value.
The mean square difference of a component for two images is the mean square difference of the component value, comparing each pixel with
the pixel in the same position of the other image. For the purposes of this computation, components are normalized to the scale [0..1].
The maximum mean square difference is identically 1.
So the higher the PSNR, the closer the images are. A luminance PSNR of 20 means the mean square difference of the luminances of the pixels
is 100 times less than the maximum possible difference, i.e. 0.01.
