Hi I am trying to compute PSNR of a video sequence, I have ref and noisy sequence. I know i can compute it for a frame using an inbuilt matlab function PSNR. Where i ama bit confuse is that how one would compute psnr of a video. Will the PSNR of a video be average of psnr computed over every Frame? Something Like
%Loop through video
PSNRofVideo(zz)=psnr(FramesNosiy{zz},FramesnotNosiy{zz});
%end
And then take the average of PSNRofVideo?Will that be correct?
Thanks anyways

I understand that you are trying to compute PSNR of a video sequence.
As a starting point, I would suggest you to go through the following File Exchange Submission:
PSNR of YUV videos
The author of the submission should be a good person to reach out to if you have any questions about the implementation.

Thanks for answering, but this does not help. I mean my question is still the same that does taking average of psnr variable which has psnr for every frame is a right approach? If not how one could do it using inbuilt matlab function since it is one of the hard constraints that we have it here. Thanks for answering though
