Hi friends !
Iam trying to project the performance of our video processing algorithm objectively in terms of PSNR. We are dealing with YUV4:2:0 videos.
The JM gives the results of the values for Y-componet
(average for all the Y frames), U componet(average for
all the U frames),V componet (average for all the V frames.
My question here is which value should I take into consideration (Y, U or V?? or the average of Y,U,V values??) for comparing with other algorithm?
I have been going through some literatures for reference. I could only find the term "Avg. PSNR" but no where clearly mentioned whether it is of Y, U ,V or avg of YUV. Can u pls let me know what the standard practice is ? I am a newbie to this stuff.
to summarize,
what will be correct PSNR for a YUV video - Y component PSNR, U component PSNR or V component PSNR or the average of the three?
Thanks in advance
