Group action recognition in soccer videos is a challenging problem due to the difficulties of group action representation and camera motion estimation. This paper presents a novel...
Let G1 be a cyclic multiplicative group of order n. It is known that the Diffie-Hellman problem is random self-reducible in G1 with respect to a fixed generator g if (n) is known....
In group-living animals, aggregation favours interactions and information exchanges between individuals, and thus allows the emergence of complex collective behaviors. In previous ...
