Evaluation of Local Spatio-temporal Features for Action Recognition
Local space-time features have recently become a popular video representation for action recognition. Several methods for feature localization and description have been proposed in the literature andExpand

Towards robust place recognition for robot localization
Localization and context interpretation are two key competences for mobile robot systems. Visual place recognition, as opposed to purely geometrical models, holds promise of higher flexibility andExpand

Improving bag-of-features action recognition with non-local cues
Local space-time features have recently shown promising results within Bag-of-Features (BoF) approach to action recognition in video. Pure local features and descriptors, however, provide onlyExpand

You live, you learn, you forget: Continuous learning of visual places with a forgetting mechanism
To fulfill the dream of having autonomous robots at home, there is a need for spatial representations augmented with semantic concepts. Vision has emerged recently as the key modality to recognizeExpand

Delay-Efficient Forwarding in SDN Assisted Mesh Networks: An Application of Shapley Value
The use of Software Defined network (SDN) as a key future Internet communications paradigm has great potential to enable efficient network communication. One of the key challenges for SDNs is toExpand
This study focuses on the area of visual indoor place recognition (e.g., in an office setting, automatically recognizing different places, such as offices, corridor, wash room, etc.). The potentialExpand
