This paper is researched intelligent surveillance system which is based on embedded system platform and wireless communication technology. To overcome interference that coming from small target movement or background light changes, moving target detection algorithm is proposed in this system. Abnormal matters at the monitor area can be detected exactly by(More)
Based on Teager-Kaiser(TK) power computation operator, the novel coexisting narrow band interference(NBI) detecting algorithm for Ultra-wideband(UWB) communications is proposed in this paper. The novel algorithm can estimate the central frequency of NBI accurately by adding the standard frequency analog signal to the TK processing branch and using the(More)
In this paper, we present a novel approach, namely directional multi-mode discriminant analysis which solves the supervised feature extraction problem by encoding the input image or high dimensional data array as a general tensor, and apply this for face and palm recognition. In the proposed scheme, the mode-k matrix of the tensor is re-sampled and(More)
The interference suppression for multi-band frequency hopping ultra-wideband communications is introduced. Based on this UWB communication system, the new interference detection algorithm is proposed. This new algorithm can be realized in low complexity and in comparatively low level sampling rate. Mathematic analysis and computer simulation for this new(More)
It is proposed that a sequential images object recognition method combining a BP neural network with the fast mass functions convergence algorithm based on DSmT. The revised Hu invariant moments are used as the image features. And the sequential images are fused in time domain in the view of information fusion. The basic belief assignment function is(More)
Many heavy metals in sediments and water have potential adverse effects on aquatic organisms such as Corbicula fluminea (O.F. Müller, 1774), a bivalve species frequently used as a biomonitor for metal pollution. Studies over the past decades examining the heavy metal uptake by C. fluminea, very few has investigated the effect of hydrodynamic conditions on(More)
