This paper propose an new image fusion method based on principal component analysis and dual-tree complex wavelet transform(DWCWT), which uses DTCWT to decompose the source images in a multi-scale and multi-direction way and then fuse the related information together according some fusion rules. This approach combines principal component analysis based image fusion rule and dual-tree complex wavelet...
Generally, the I/O device speed was slower because each guest domain was not well considered to be executed on virtual machine monitor (VMM). In other words, the guest domain has some problems in the architecture of communication and data transmission on VMM. The I/O device virtualization models in virtual machine (VM) environments require involvement of a VMM and/or a privileged VM for each I/O operation,...
Iris, as a biometric with the best performance in the stability, reliability and non-invasiveness, can obtain an even more high recognition rate than other biometrics, such as fingerprint, face and voice. However, it is difficult to extract iris features from an eye image. In this paper, we demonstrate a scheme for iris detection and extraction based on John Daugman's Integro-differential operator...
The lifting scheme provides us a powerful tool for constructing biorthogonal wavelets. Meanwhile, it is a new explanation of first generation wavelets, i.e., any first generation wavelets filter can be decomposed into some lifting steps. A method of decomposing biorthogonal wavelets filters into lifting steps by solving equations is presented in this paper. The lifting coefficients can be obtained...
Remote user authentication scheme is a mechanism which allows a server to authenticate a remote user over insecure channel. Recently, Goriparthi et al. made an enhancement based on Das et al.'s remote user authentication scheme using bilinear pairings. The scheme has the merits of no verification table, freely changing password and preventing the forgery attack and the replay attack. This paper, however,...
Rough set theory is not only a new mathematical tool dealing with vagueness and uncertainty but also a new effective soft computing method. It was been widely used in the area of artificial intelligence, data mining, pattern recognition, decision analysis, fault diagnosis and so on. So according to the rough set theory and its extensive applications, the application of rough set theory to algebra...
Digital Rights Management (DRM) system is the effective schemes for digital transactions. A novel authentication scheme of the DRM system based on multimodal biometric verification and watermarking technique is described in this paper, which is based on highly secure iris recognition and face recognition and their feature fusion recognition is described, which is can achieve the rights management...
