Abstract :
We propose a video retrieval scheme indexing the object´s motion trajectory information. The motion trajectories of moving objects are partitioned by fixed time intervals. Each segmented motion trajectory is described using the coefficients of 2nd order polynomials that represent the centroids of the moving objects in time evolution. The set of polynomial coefficients is used as a motion trajectory descriptor. The proposed scheme provides small-sized indexing and low matching complexity
