In this paper, we present a method for fusing face and iris biometrics using single near infrared (NIR) image. Fusion of NIR face and iris modalities is a natural way of doing multi-model biometrics because they can be acquired in a single image. An NIR face image is taken using a high resolution NIR camera. Face and iris are segmented from the same NIR(More)
Face images captured in different spectral bands, e.g. , in visual (VIS) and near infrared (NIR), are said to be heterogeneous. Although a person’s face looks different in heterogeneous images, it should be classified as being from the same individual. In this paper, we present a new method, called face analogy, in the analysis-by-synthesis framework, for(More)
In this paper, we present a robust and accurate system for outdoor (as well as indoor) face recognition, based on a recently developed enhanced near-infrared (ENIR) imaging device. Using a narrow band NIR laser generator instead of LED lights for active frontal illumination, the ENIR device can provide face images of good quality even under sunlight.(More)
AIMS To evaluate the production of an extracellular serine protease by Dactylella shizishanna and its potential as a pathogenesis factor. METHODS AND RESULTS An extracellular alkaline serine protease (Ds1) was purified and characterized from the nematode-trapping fungus D. shizishanna using cation-exchange chromatography and hydrophobic interaction(More)
In this paper, a Bayesian method for face recognition is proposed based on Markov Random Fields (MRF) modeling. Constraints on image features as well as contextual relationships between them are explored and encoded into a cost function derived based on a statistical model of MRF. Gabor wavelet coefficients are used as the base features, and relationships(More)
An improved quantum genetic algorithm (IQGA) is proposed in this paper, which codes the chromosome with probability amplitudes represented by sine and cosine functions, and uses an adaptive strategy of the rotation angle to update the population. Then the mutation operation is considered in this improved quantum genetic algorithm (MIQGA). Rapid convergence(More)
We study the relationship between bipartite entanglement, subsystem particle number and topology in a half-filled free fermion system. It is proposed that the spin-projected particle numbers can distinguish the quantum spin Hall state from other states, and can be used to establish a new topological index for the system. Furthermore, we apply the new(More)
Biometric identification makes use of the physiological or behavioral characteristics of people, such as fingerprint, iris, face, palmprint, gait, and voice, for personal identification [1], which provides advantages over nonbiometric methods such as password, PIN, and ID cards. Its promising applications as well as the theoretical challenges have gotten(More)
Attitude determination is an important part for Autonomous Underwater Vehicles (AUVs) to achieve their designed mission. This paper presents a novel attitude solution based on the hydrodynamic model. The hydrodynamic parameters can be calculated by the known hydrological parameters. Meanwhile, the pressure information of AUV's surface can be measured by the(More)
