Fast realistic multi-action recognition using mined dense spatio-temporal features
Within the field of action recognition, features and descriptors are often engineered to be sparse and invariant to transformation. While sparsity makes the problem tractable, it ...

Improving AR using Shadows Arising from Natural Illumination Distribution in Video Sequences
In this paper, we propose a method for generating realistic shadows of virtual objects inserted into a real video sequence. Our aim is to improve and extend the work of [1], which...

Large human communication networks: patterns and a utility-driven generator
Given a real, and weighted person-to-person network which changes over time, what can we say about the cliques that it contains? Do the incidents of communication, or weights on t...

Downtilted Base Station Antennas - A Simulation Model Proposal and Impact on HSPA and LTE Performance
— This paper proposes a low-complexity model for vertical antenna radiation patterns, e.g. for inclusion in systemlevel simulations. They can be seen as extensions to the horizon...
