In this paper we introduce a new video description framework that replaces traditional Bag-of-Words with a combination of Fisher Kernels (FK) and Vector of Locally Aggregated Descriptors (VLAD). ...
We show that our framework is highly general and is not dependent on a particular type of descriptor. It achieves state-ofthe-art results in several classification scenarios. ...
In this context, we propose a new way of representing the descriptor information that exploits the advantages of both, FK and VLAD representations, in a unified framework. ...
