Actions-Synchronization-with-Dynamic-Time-Warping

Synchronization of videos in which the actor performs the same action: in particular sports videos including pole vault and dives

Idea:

  • Extract for each video of a class the features (poses of the actors) with Mask R-CNN.
  • Create a matrix of video distances of a class.
  • Apply a hierarchical clustering algorithm based on the distances matrix to understand which pairs apply dynamic time warping.
  • For each level of the resulting tree (Dendrogram) it is possible to reproduce subtree videos in a synchronized way.

To run:

  • Download the videos from the google drive link on this page and put them in the video folder.
  • Choose which subtree to synchronize from the dendrogram and the childs table.
