Divotion/SRQA_Database

Folder Description:

• GT -- original Full HD uncompressed videos. In the folder corresponding to each video there is "GT.yuv" file (the video itself) and "frames" folder containing all frames of the video
• GTCompressed -- videos from "GT" folder with reduced resolution and compressed with different video codecs. The folder corresponding to each of the video sequences contains folders with frames of the compressed videos. Folders are named in the following format: "<scale factor>_<codec name>_<values of target bitrate or qp>"
• GTCompressedFullHD -- the same videos as in "GTCompressed", but upscaled to Full HD using bicubic interpolation. These videos are used to run FR metrics.
• GTCrops -- high-saliency crops from videos in "GT" folder. The folder corresponding to each video contains the crops from that video.
• DistVideos -- videos from the "GTCompressed" folder processed with Super-Resolution methods. The folders corresponding to each video sequence contain folders with frames of distorted videos, named in the following format: "<SR method name>_<scale factor>_<codec name>_<values of target bitrate or qp>"
• DistCrops -- high-saliency crops from videos from "DistVideos" folder, corresponding to crops from "GTCrops". Storage format is the same as in the "DistVideos" folder.
• subjective_scores -- folder with subjective scores of all videos. Each folder inside contains subjective scores for one of the datasets: "subjective_scores_fullhd" -- for SR-enhanced Full HD videos, "subjective_scores_crops" -- for SR-enhanced crops of Full HD videos, "subjective_scores_codecs" -- for non-SR videos.
