Equal but different: a contextual analysis of duplicated videos on YouTube

Tiago Rodrigues, Fabrício Benevenuto, Virgílio Almeida, Jussara Almeida, Marcos Gonçalves
2010 Journal of the Brazilian Computer Society  
Since users can independently share videos in these systems, some videos can be duplicates (i.e., identical or very similar videos).  ...  Quantifying these differences is important to understand how users associate metadata to videos and to understand possible reasons that influence the popularity of videos, which is crucial for video information  ...  Recently, we have approached the problem of identifying these users using a machine learning approach [4, 5] .  ...

Video Skimming

Vivekraj V. K., Debashis Sen, Balasubramanian Raman
2019 ACM Computing Surveys  
We present a taxonomy of video skimming approaches, and discuss their evolution highlighting key advances.  ...  Being dynamic in nature, video skimming, through temporal connectivity, allows better understanding of the video from its summary.  ...  While near duplicate keyframe identification on the basis of visual similarity is performed in [59] , dimensionality reduction based approach is suggested in [125] for user videos.  ...
