Video quality evaluation in the cloud
2012
2012 19th International Packet Video Workshop (PV)
Preserved Fulltext
We therefore propose in this contribution a cloud-based extension of the QualityCrowd framework in order to perform subjective quality evaluation as a cloud application. ...
Video quality evaluation with subjective testing is both time consuming and expensive. ...
CONCLUSION We extended the QualityCrowd framework for web-based video quality evaluation with crowdsourcing into the cloud and introduced video quality evaluation as a cloud application. ...

Cloud computing provides a promising solution to cope with the increased complexity in new video compression standards and the increased data volume in video source. ...
To facilitate cloud computing for real-time video encoding, in this paper we evaluate the amount of computing resource needed for H.264 and H.264 SVC encoding. ...
Considering that we are also evaluating the C-R-D performance of H.264 SVC, we adopt the newly developed quality metric in [9] for quality measurement. ...

Essential to our framework is the realization that the accuracy, rather than the density, of pixel flows is what is required for high-quality video enhancement. ...
Instead, we propose a lightweight flow estimation algorithm; it fuses the sparse point cloud data and (even sparser and less reliable) IMU data available in modern autonomous agents to estimate the flow ...
Overall Evaluation Results Overview OURS-M and OURS-S consistently outperform the baselines in both quality and speed. ...
