Hi friends !

Iam trying to project the performance of our video processing algorith
objectively in terms of PSNR and SSIM. We are dealing with YV12 videos. Ia
using the MSU Video Quality measurement tool to compute the PSNR and SSI
values. Here they give the options to compute the values for Y-compone
alone (and average for all the Y frames), U componet alone (and average fo
all the U frames),V componet alone (and average for all the V frames.

My question here is which value should I take into consideration (Y, U o
V?? or the average of Y,U,V values??) for comparing with unprocessed video



to summarize,

what will be correct PSNR for a YUV video - Y component PSNR, U componen
PSNR or V component PSNR or the average of the three?

Pls give ur valuable inputs..

Thanks in advance,
Praveen
