AVT-VQDB-UHD-1: A Large Scale Video Quality Database for UHD-1

1 code implementation • IEEE International Symposium on Multimedia 2019 • Rakesh Rao Ramachandra Rao, Steve Göring, Werner Robitza, Bernhard Feiten, Alexander Raake

In the second step, different state-of-the-art objective quality models were applied to all videos and their performance was analyzed in comparison with the subjective ratings, e. g. using Netflix's VMAF.
