In this paper, we focus on a new application of mobile visual search: snapping a photo with a mobile device of a video playing on a TV screen to automatically retrieve and stream the remainder of the video to the mobile device. When the user takes a photo of the video, the captured query frame may contain too few useful features for good retrieval performance. We design and implement a new algorithm...
Reconfigurable computing (RC) has been viewed as an efficient solution to achieve high performance and flexibility. Hardware tasks can be dynamically placed on and removed from reconfigurable platforms. Field-programmable gate arrays (FPGA) provide partially runtime reconfiguration (PRTR) at runtime. However, this reconfiguration will lead to more time overhead. An efficient algorithm to manage empty...
Efficiency and fairness are the two critical and conflicting criterion indicators to measure radio resource management performance including the power and transmit control in the cognitive context. The best tradeoff is achieved using the dynamic game-theoretical approach in this paper, from the individual rationality and the social fairness perspective. Therefore, a two-step resource management scheme...
We propose a set of distributed algorithms for in-network path planning that enables a distributed sensor network navigation service in dynamic environments. Different from existing algorithms that use frequent or periodic flooding, our algorithms exploit geographic information of sensors to construct and maintain navigation links. Based on a partial reversal method of directed acyclic graphs, our...
