Video descriptors

Participants : Heng Wang, Dan Oneata, Cordelia Schmid [correspondant] , Jakob Verbeek.

We have developed and made on-line available software for video description based on dense trajectories and motion boundary histograms, which are presented in [9] . The trajectories capture the local motion information of the video. A state-of- the-art optical flow algorithm enables a robust and efficient extraction of the dense trajectories. Descriptors are aligned with the trajectories and based on motion boundary histograms (MBH) which are robust to camera motion. The code is available at http://lear.inrialpes.fr/~wang/improved_trajectories .
