                         semantic information of videos. In this work, a global video 
                         descriptor based on orientation tensors is proposed. This 
                         descriptor is obtained by combining polynomial coefficients 
                         calculated for each image in a video. The coefficients are found 
                         through the projection of the optical flow on Legendre 
                         polynomials, reducing the dimension of per frame motion 
                         estimations. The sequence of coefficients are then combined using 
                         orientation tensors. The global tensor descriptor created is 
                         evaluated by a classification of the KTH video database with a SVM
