Obtaining a dynamically updated background reference image is an important and challenging task for video applications using background subtraction. This paper proposes a novel algorithm for dynamic video background reconstruction with move-then-stop arbitrary-long time video object detection enabled.
SUMMARY An effective design of multistage parallel interference cancellation (PIC) receiver using blind adaptive (BA) despreader and pre-respreader interference estimator for uplink CDMA is proposed and analysed. A novel algorithm is designed, which exploits constant modulus (CM) property of the users' transmitted signals and inherent channel condition to(More)
Particle swarm optimization (PSO) is a well- known technique in artificial intelligence (AI) for n- dimensional optimization problems. In this paper we extend the application of PSO to physical layer of communication systems and propose a simple target-customized PSO algorithm that could be used in centralized iterative optimization techniques. It is(More)
Distributed processing is an essential part of collaborative computing techniques over ad-hoc networks. In this paper, a generalized particle swarm optimization (PSO) model for communication networks is introduced. A modified version of PSO, called trained PSO (TPSO), consisting of distributed particles that are adapted to reduce traffic and computational(More)
In this paper, we introduce blind adaptive interference cancellation for a practical uplink CDMA effected by multiple access interference (MAI) in cooperative communications systems scenario. During the collaboration phase, each paired users exchange their data to communicate with the base-station by using their own and pairing userspsila channels to(More)
