In current society, reliable identification and verification of individuals are becoming more and more necessary tasks for many fields, not only in police environment, but also in civilian applications, such as access control or financial transactions. Biometric systems are used nowadays in these fields, offering greater convenience and several advantages over traditional security methods based on something that you know (password) or something that you have (keys). In this paper, we propose an efficient online personal identification system based on Multi-Spectral Palmprint (MSP) images using Contourlet Transform (CT) and Gabor Filter (GF) response. In this study, the spectrum image is characterized by the contourlet coefficients sub-bands. Then, we use the Hidden Markov Model (HMM) for modeling the observation vector. In addition, the same spectrum is filtered by the Gabor filter. The real and imaginary responses of the filtering image are used to create another observation vector. Subsequently, the two sub-systems are integrated in order to construct an efficient multi-modal identification system based on matching score level fusion. Our experimental results show the effectiveness and reliability of the proposed method, which brings both high identification and accuracy rate.

For the bandwidth limitation and unstable network topology in wireless video sensor networks (WVSNs), an energy-efficient, distance-aware and QoS-guaranteed multi-path routing (EDQMR) protocol for WVSNs is proposed in this paper. The optimum routing is selected in the protocol comprehensively considering constrains such as delay, the maximum hop distance and the node residual energy. Simulation results show that when delay requirements are met, compared to existing protocol AOMDV, the proposed EDQMR can significantly enhance the packet delivery ratio while prolonging the network lifetime.
It's well known that sparse signals can be sensed with a reduced number of projections and then reconstructed if compressive sensing (CS) is employed. We consider the problem of designing the projection matrix Φ ...
