Video quality assessment databases

1080i_Videos Subjective quality of HD videos (using ACR-HR and SAMVIQ methods)

This database is composed by 24 HD original sequences and 168 distorted videos encoding in H264. 28 observers rate videos with ACR-HR and SAMVIQ methods. Read more.

DIBR_Videos Videos quality assessment (using ACR-HR)

The database contains 102 video of 6 seconds in 1024x768 resolution with DIBR impairments and with 15 and 30 frames per second. An ACR-HR experiment provide subjective scores of 32 observers. Read more.

Eyetracker_SD_2009_12 Eye tracking and quality assessment (with the ACR-HR method) on SD videos

This database is composed by 20 original SD videos and 80 distorted videos by H264 coding with transmission errors. The H264 streams, subjective scores (ACR-HR) and eyetracker raw data of 30 observers are available. Read more.

Free-Viewpoint_synthesized_videos Free-Viewpoint synthesized videos with subjective quality measures (ACR-HR)

The database contains 264 video sequences of 100 frames (around 7 seconds at 15f ps) in 1024x768 and 1920x1080 pixels resolution. 6 different multiview sequences, 7 different degradations with 3 different bitrares and using blending or not are considered to generate the videos.  Finally, 27 observers compare these videos and the originals with the ACR-HR method. Read more.

H264_AVC_vs_SVC Subjective comparison between H264/AVC and H.264/SVC for mobile videos (with SAMVIQ)

This database is composed by 4 original sequences and 48 distorted videos by H264 and H264/SVC coding, with different quality, without transmission errors, in QVGA (320x240) and VGA (640x480). We used SAMVIQ as test methodolog for 15 observers. This database can be used to compare H.264/AVC and H.264/SVC coding in a mobile context. Read more.

H264_HD_vs_Upscaling_and_Interlacing Subjective quality to compare FullHD vs Upscaling and Interlacing H.264 coded videos (using ACR-HR 11 levels)

This database is composed by 3 original sequences and 87 distorted videos by H264 coding in 6 HD formats. ACR-HR was used to compute subjective scores of 26 observers. This database can provide information about the better HD format depending the bit-rate. Read more.

Influence_Content Subjective quality assessment of videos using ACR-HR method

This database is composed by 60 orginal VGA (640x480) videos and 240 distorted videos by H.264/SVC coding. This database provide information about the influence of the content. 29 observers rate these VGA videos with an ACR-HR method. Read more.

JEG264HMIX1 Subjective scores, HMIX and PCAP files for HD videos with differents transmission chains (with ACR-HR method)

This database is composed by 10 original HD sequences. For each content, the reference and 16 different degradation with several encoders, decoders and packet loss schemes were used including transcoding scenarios, spatial and temporal subsampling were subjectively evaluated. ACR-HR test methodology were used with 27 obsevers. Read more.

SD_RoI Subjective quality evaluation on SD videos with transmission errors in Region of Interest or not (ACR-HR method)

This database is composed by 6 original SD (720x576 pixels) videos and 84 distorted videos by H264 coding with or without transmission errors. The transmission errors are located in the ROI, near the ROI or far away the ROI. The frame rate is 50Hz. 25 observers rate these videos with ACR-HR method. Read more.

SD_vs_HD_H264 Quality assessment of HD and SD video contents using Pair Comparison

The database contains 28 HD and 8 QHD video sequences of 10 seconds at 25 frames per second. Videos are generated with H264 coding and different bitrates were selected such that a minimum quality level for typical HDTV scenarios is guaranteed. MOS scores were obtained by a comparative method with an adjectival categorical judgment experiment (pair comparison with 7 categories) and 21 naives observers. Read more.

SVC4QoE_QP0_QP1 Subjective quality of H.264/SVC videos using ACR-HR method in VGA

This database is composed by 11 VGA original sequences and 313 distorted videos by H264 and H264/SVC coding. We compute subjectives scores of these videos of 27 observers with ACR-HR method. Read more.

SVC4QoE_Replace_Slice Subjective quality assessment (with ACR-HR method) of VGA videos with simulated transmissions error on H.264/SVC coding

This database is composed by 9 VGA (640x480 pixels) original sequences and 131 distorted videos by H264 and H264/SVC coding with or without transmission errors. The frame rate is 60Hz. 29 observers rate these videos with ACR-HR method. Read more.

SVC4QoE_Temporal_Switch Subjective quality scores (using ACR-HR) for videos switching between 2 qualities

This database provide some videos with switching between 2 qualities. This database is composed by 11 VGA (640x480 pixels) original sequences and 379 distorted videos by H264 and H264/SVC coding and switching between SVC base layer and SVC enhanced layer. Subjective scores (ACR-HR) of 28 observers are provided. Read more.

VQEG_HDTV_Pool2 Subjective quality scores on 1080i videos (with ACR-HR method)

This database is composed by 9 original sequences and 159 distorted videos by H.264 and MPEG2 coding with and without transmission error. ACR are used to compute subjective scores of 24 observers. Read more.
