Abstract:

To exploit sensitive, accurate and convenient detection techniques for nucleic acid sequences can help to overcome the defects of current fluorescence detection method. Raman spectroscopy represents one family of methods that may offer such potential. In this paper, G•C base pairs and C•U mispairs were studied by Raman spectral characterization of single-strand homopolynucleotides, i.e. polyguanylic acid (PolyG), polycytidylic acid (PolyC) and polyuridylic acid (PolyU), and their equimolar complexes PolyG•PolyC and PolyC•PolyU in solution of 0.14 M Na+, pH7.0.

Biometric classification plays a key role in fingerprint characterization, especially in the identification process. In fact, reducing the number of comparisons in biometric recognition systems is essential when dealing with large-scale databases.

The general approach of fingerprint classification requires pre-processing techniques that are usually computationally expensive.

Abstract:

In Finger-Knuckle-Print (FKP) recognition, feature extraction plays a very important role in the overall system performance. This paper merges two types of the histograms of oriented gradients (HOG)-based features extracted from reflectance and illumination images for FKP-based identification. The Adaptive Single Scale Retinex (ASSR) algorithm has been used to extract the illumination and the reflectance images from each FKP image. Serial feature fusion is used to form a large feature vector for each user, and extract the distinctive features in the higher-dimension vector space. Finally, the

Abstract:

Finger vein pattern has become one of the most promising biometric identifiers. In this paper, a robust method based on Bag-of-Words (BoW) is developed for finger vein verification. Firstly, some robust and discriminative visual words are learned from local base features such as Local Binary Pattern (LBP), Mean Curvature and Webber Local Descriptor (WLD). We name these visual words as Finger Vein Textons (FVTs). Secondly, each image is mapped into a FVTs matrix. Finally, spatial pyramid matching (SPM) method is applied to maintain spatial layout information by representing each image as pyrami

The security of people requires a beefy guarantee in our society, particularly, with the spread of terrorism throughout the world. In this context, palmprint identification based on texture analysis is amongst the pattern recognition applications to recognize people. In this article, the researchers investigated a deep texture analysis for the palmprint texture pattern representation based on a fusion between several texture information extractions through multiple descriptors, such as HOG and Gabor Filters, Fractal dimensions and GLCM corresponding respectively to the frequency, model, and st

Palmprint is widely used in personal identification for an accurate and robust recognition. Multispectral palmprint images capture under different illumination, including Red, Green, Blue and Infrared maybe contribute to the recognition results. However, the evaluation of selection and fusion of how this different spectral images can contribute to improve the robustness of the recognition system is imperative.

Abstract The General University Requirements (GUR) is the core general education component of the new 4-year undergraduate curriculum at The Hong Kong Polytechnic University (PolyU) commencing from the 2012/2013 academic year. The major objective of the GUR is to widen students’ horizons and promote their holistic development in their undergraduate years. To evaluate the perceived effectiveness of the GUR in its second year implementation, 18 focus group interviews (n=74 students) were conducted in the 2013/2014 academic year.

With the wide applications of face recognition techniques, spoofing detection is playing an important role in the security systems and has drawn much attention. This research presents a multispectral face anti-spoofing method working with both visible (VIS) and near-infrared (NIR) spectra imaging, which exploits VIS–NIR image consistency for spoofing detection. First, we use part-based methods to extract illumination robust local descriptors, and then the consistency is calculated to perform spoofing detection. In order to further exploit multispectral correlation in local patches and to be fr

Region covariance matrices (RCMs) as feature descriptors have been developed due to the advantages of low dimensionality, being scale and illumination independent. How to define a feature mapping vector for the RCMs construction of strong discriminating ability is still an open issue. In this paper, there is a focus on finding a more efficient feature mapping vector for RCMs as palmprint descriptors based on Gabor magnitude and phase (GMP) information. Specially, Gabor magnitude (GM) features of each palmprint image approximate a lognormal distribution. For palmprint recognition, the logarithm

Multispectral palmprint recognition system (MPRS) is an essential technology for effective human identification and verification tasks. To improve the accuracy and performance of MPRS, a novel approach based on autoencoder (AE) and regularized extreme learning machine (RELM) is proposed in this paper. The proposed approach is intended to make the recognition faster by reducing the number of palmprint features without degrading the accuracy of classifier. To achieve this objective, first, the region of interest (ROI) from palmprint images is extracted by David Zhang’s method. Second, an efficie

A novel biometric authentication information hiding method based on the sparse representation is proposed for enhancing the security of biometric information transmitted in the network. In order to make good use of abundant information of the cover image, the sparse representation method is adopted to exploit the correlation between the cover and biometric images. Thus, the biometric image is divided into two parts. The first part is the reconstructed image, and the other part is the residual image. The biometric authentication image cannot be restored by any one part. The residual image and s

The purpose of this research is to analyse integration of multimodal and multifeature biometric system using feature level fusion to achieve better performance. The main aim of the proposed system is to increase the recognition accuracy using feature level fusion. The features at the feature level fusion are raw biometric data which contains rich information when compared to decision and matching score level fusion.
