Wireless intrusion detection systems are an important addition to the security of wireless local area networks (WLANs). We focus on intrusion detection and security consideration in wireless local area networks. We present intrusion detection for WLANs, give wireless intrusion detection systems and system architecture considerations. We also present a(More)
This paper describes a new framework for video dehazing, the process of restoring the visibility of the videos taken under foggy scenes. The framework builds upon techniques in single image dehazing, optical flow estimation and Markov random field. It aims at improving the temporal and spatial coherence of the dehazed video. In this framework, we first(More)
Dynamic programming (DP) is a popular and efficient technique in many scientific applications such as computational biology. Nevertheless, its performance is limited due to the burgeoning volume of scientific data, and parallelism is necessary and crucial to keep the computation time at acceptable levels. The intrinsically strong data dependency of dynamic(More)
