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)
We present a novel unified framework for simulating burning phenomena of thin-shell objects such as paper, cloth, etc. A gradient-based spreading model is proposed to simulate the movement of fire on thin-shell objects. To simulate the crumpling and deformation of thin-shell objects when burning, we present an FFD-based deformation model which takes the(More)
In this paper, we present a new algorithm to remove haze from a single image. The proposed algorithm extracts transmission iteratively under the assumption that large-scale chromaticity variations are due to transmission while small-scale luminance variations are due to scene albedo. A nonlinear edge-preserving filter is introduced to incrementally refine(More)
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)
A micro potentiometric immunosensor based on mixed SAMs wrapped nano-spheres array for the detection of hemoglobin-A1c level is presented in this paper. Nano-spheres array is prepared by wrapping nano-gold particle with mixed SAMs on the surface of micro immunosensor. Mixed SAMs make the nano-gold particles distribute uniformly without aggregation and(More)
Gold nanoparticles (AuNPs) embedded in chitosan (CHI) film, well-dispersed and smaller in size (about 10 nm), were fabricated by one-step electrodeposion on Au microelectrode in solution containing chitosan and chloride trihydrate. The nano-structure CHI-AuNPs composite film offers abundant amine groups, good conductivity, excellent biocompatibility and(More)
