Special Session on Perceptual Quality Assessment in Networked Video Applications

Recent advances in video coding and wired/wireless networking have propelled many exciting networked video applications to the center stage of people’s life.  Due to the heterogeneity and dynamics of the network, such applications require dynamic adjustment of video coding parameters (including quantization, frame rate, frame size, and error resilience features) and error control mechanisms.  The decoded video may suffer from packet loss and delay jitter in addition to coding artifacts. From the perspective of the service providers, it is critical to have an effective way to measure or predict the end user satisfaction under different network conditions, and to adjust the system operating parameters accordingly. As a witness of such demand, there are ongoing standardization efforts to design hybrid quality metrics that use both bitstream information and decoded content as inputs to a video quality metric.  This special session will provide a forum for exchanging new ideas specifically important for networked video applications. Topics of interests include, but are not limited to:

  • Impact of spatial and temporal resolution on video quality
  • Effect of fluctuation of spatial, temporal and amplitude resolutions on the perceived quality
  • Non-reference and hybrid quality metrics
  • Impact of packet loss, delay jitter, and audio-visual synchronization in the quality of experience
  • Quality monitoring and feedback in networked video applications
  • Perceptually optimized error control
  • Services oriented quality assessment (Mobile video quality assessment, Stereo and multiview video quality assessment, HDTV quality assessment …)

Prospective authors should prepare and submit the paper following the instruction for the regular papers posted on the workshop website. Papers submitted to the special session will go through a regular review process. The authors are encouraged to inform the special session organizers about their intent to submit the paper with a paper title.
