Length-independent refinement of video quality metrics based on multiway data analysis

Clemens Horch, Christian Keimel, Julian Habigt, Klaus Diepold
2013 2013 IEEE International Conference on Image Processing  
In previous publications it has been shown that no-reference video quality metrics based on a data analysis approach rather than on modeling the human visual system lead to very promising results and outperform  ...  This contribution shows a way of refining these multiway quality metrics in order to make them more suitable for real-life applications and maintaining the performance at the same time.  ...  CONCLUSION We improved the design of video quality metrics using multiway data analysis by making the training and the quality prediction independent of the length of video sequences.  ...

Motion layer extraction in the presence of occlusion using graph cuts

Jiangjian Xiao, M. Shah
2005 IEEE Transactions on Pattern Analysis and Machine Intelligence  
Extracting layers from video is very important for video representation, analysis, compression, and synthesis.  ...  Third, an occlusion order constraint on multiple frames is explored, which enforces that the occlusion area increases with the temporal order in a short period and effectively maintains segmentation consistency  ...  This material is based upon work funded in part by the US Government.  ...
