Video phylogeny tree reconstruction using aging measures

Simone Milani, Paolo Bestagini, Stefano Tubaro
2017 2017 25th European Signal Processing Conference (EUSIPCO)  
The use of processing age allows a forensic analyst to blindly select a smaller amount of significant video pairs to be compared for VPT reconstruction.  ...  The need of authenticating these contents and tracing back their history has led to the investigation of forensic algorithms for the reconstruction of the video phylogeny tree (VPT), i.e., an acyclic directed  ...  Conversely, D geom and D luma are composed by chains of videos to which only one operation (geometrical or luminance-based) and one coding step were applied.  ...

A new motion histogram to index motion content in video segments

Haoran Yi, Deepu Rajan, Liang-Tien Chia
2005 Pattern Recognition Letters  
A new motion feature for video indexing is proposed in this paper. The motion content of the video at pixel level, is represented as a Pixel Change Ratio Map (PCRM).  ...  The PCRM enables us to capture the intensity of motion in a video sequence. It also indicates the spatial location and size of the moving object.  ...  Therefore, we utilize the K-means algorithm (Duda and Hart, 1973) to perform data-driven initialization instead of a random one.  ...
