SRC Database Enhancement and Analysis for Video Quality Assessment

This project focuses on enhancing the SRC database for video quality assessment by cutting some sequences into shorter videos, making CDVL database sequences available for easier download, and creating a Virtual Machine for recreating videos for analysis.

  1. Discussion for JEG in Ghent Marcus Barkowsky

  2. Marcus Barkowsky

  3. Status SRC • SRC database • 64 High Quality HDTV sequences • 6 RenderedMovies • 22 User generated contents • Gaming content • Gold dataset 2012 selected (10 sequences) • A first version of manual annotation regarding the sequencecharacteristicsisavailable • Todo: • Somesequencesneed to becutintoshortervideos (notably the RenderedMovies) • It wouldbenice to have the sequencesfrom the CDVL databaseavailable on ftp for easierdownload Marcus Barkowsky

  4. StatusPVS • The Goldset 2012 wasencoded by AGH with • ~600 differentparameter settings in x264 • ~600 differentparameter settings in JM • The 12000 sequences(108GB) canbedownloadedfrom: • ftp://ftp.ivc.polytech.univ-nantes.fr/ VQEG/JEG/HYBRID/database/ • Soon a mirrorat AGH willbeinstalled Marcus Barkowsky

  5. Status PVS • Todo: • Create a Virtual Machine allowing for recreatingthesevideos • Create the same PVS for more SRC • Transmit thesevideos over variouslossy/lossless transmission channels • Remarks/Questions: • The HMIX2 files in compressed bz2 format take about 800GB. It wouldprobablybe more convenient to runthislocally. • The PVS wouldbevery large and canbecreated in the sameprocess Marcus Barkowsky

  6. H.264 databasedetails • Presentation by Lucjan Marcus Barkowsky

  7. Status objective indicators • Objective Algorithms are currentlyrun on the database (SSIM, PSNR, VQM, …) • Isolatedindicators are evaluated as well(blockiness, blurriness, jerkinessfromAccepTV, variousalgorithmsfrom AGH) • Todo • Runfurther objective measurementalgorithms Marcus Barkowsky

  8. StatusEstimating MOS • Todo • Developstatisticaltools to • Select and alignvarious objective algorithmresults • Provide information whichsequences have to go into a subjective experiment, i.e. based on order classification Marcus Barkowsky

  9. Testplan discussion • New structures in the testplan in the Appendices (seethere) Marcus Barkowsky

  10. HEVC database • Glenn isgoing to presentdetails Marcus Barkowsky

  11. Addition of other types of media/degradations • Presentation by Anthony Marcus Barkowsky

  12. Status for developingHybridmeasurement • Todo: • Studentcompetition organisation? Marcus Barkowsky

  13. Furtherworkideas • Furtherwork on HEVC XML file creation • Furtherwork on balanced SRC selectionalgorithm • Predictingmanuallyvoted SRC selectionfeaturesincludingmeasuring of performance of existingalgorithms Marcus Barkowsky
