Full-hd Hevc-encoded Video Quality Assessment Database

چکیده
This work presents a large dataset of High Efficiency Video Coding (HEVC) sequences aimed at creating a reference for researchers involved in video quality research. Ten sequences with different characteristics have been encoded with different parameters, resulting in 59520 videos which have been processed to provide objective quality measurements at frame-level granularity. The ultimate objective is to make this database, which is already publicly available, a reference for researchers involved in designing hybrid video quality measurements, so that it can be used for both investigation and reproduction of results. Besides describing the context and database content, this paper also provides a glimpse on the possible uses of the already available data, as well as the two directions towards which the project is being expanded: incorporating new objective measurements and evaluating quality for corrupted videos with realistic loss traces.

متن کاملAdaptive Quantization Matrices for High Definition Resolutions in Scalable HEVC
HEVC contains an option to enable custom quantization matrices (QMs), which are designed based on the Human Visual System (HVS) and a 2D Contrast Sensitivity Function (CSF). Visual Display Units (VDUs), capable of displaying video data at High Definition (HD) and Ultra HD (UHD) display resolutions, are frequently utilized on a global scale. Video compression artifacts that are present due to hi...
متن کاملComparison of High Efficiency Video Coding (hevc) Performance with H.264 Advanced Video Coding (avc)
High Efficient video coding (HEVC) will be replacing the current standard, H.264/MPEG-4 Advanced Video Coding (AVC). The main goal for HEVC standardization is to deliver equal video quality for half the bit-rate of H.264/MPEG-4 AVC. Other objective of HEVC is to support higher resolution than the current high definition (HD) of 1920 × 1080. Nevertheless, HEVC standard has similar structure desi...
