• A Spatial Pyramidal Decomposition Method for Finger Vein Recognition Using Local Descriptors  
  by Badreddine Griouz, Rafik Djemili, Hocine Bourouba, Hakim Doghmane 
  Abstract: Finger vein patterns have been proved as one of the most promising biometric modality for its convenience and security. Most of the current available finger vein recognition methods utilize features from a segmented blood vessel network. This manner of processing however may not provide optimal recognition accuracies as reported in many studies. Therefore, this paper proposes in the feature extraction stage, the use of the spatial pyramid decomposition (SPD) method aiming at partitioning the finger vein images into increasingly fine sub-regions from which local texture descriptors are obtained. The descriptors adopted in this paper are local binary pattern (LPB), binarized statistical image feature (BSIF) and local phase quantization (LPQ). The performance of the proposed approach evaluated on two publicly databases PolyU and SDUMLA achieves a recognition accuracy higher than that of some existing systems reported in the literature for both the SDUMLA and the PolyU databases.

• Multi-pose facial expression recognition using Rectangular HOG feature extractor and Label-Consistent KSVD classifier  
  by Ali Muhamed Ali, Hanqi Zhuang, Ali Ibrahim 
  Abstract: In this paper, a new approach to the classification of facial expressions from multiple pose images is proposed. In this approach, a Rectangular Histogram of Oriented Gradient (R-HOG) algorithm is first designed to extract features of face images. The parameters of the R-HOG algorithm, which is a modification of the original HOG algorithm include cell shape, cell size, block size, and the number of orientation bins. The R-HOG is capable of capturing more discriminative texture features of different facial expressions. In addition, a supervised dictionary learning classifier, the Label Consistent K-SVD (LC-KSVD) algorithm, is adopted to recognize the facial expression of the subject. To investigate its effectiveness, the proposed technique was applied to classify emotional states of the face images in the two public available facial expression datasets: KDFE and RafD. The experiment study showed that the new method outperformed in many aspects those methods reported in the literature tested with the same datasets. First, the new method handles pose variations better. Second, it is more robust in cases where the size of a training dataset is small. Finally, it's accuracy performance is more consistent measured by standard deviations.

• An Accurate and Fast Method for Eyelid Detection  
  by Ahmed A.K. Tahir, Steluta Anghelus 
  Abstract: A novel method called Refine-Connect-Extend-Smooth (R-C-E-S) for detecting eyelids is presented. It consists of four algorithms, Canny edge detector with Prewitt operator, Modified Refine Edge Map (MREM), Connect Edges-Extend (CEE) and Smooth Curve (SC). The method is not based on pre-assumptions that consider eyelids as parabola or lines and it does not use curve fitting algorithm, therefore sever deviation of the detected eyelid curve from the actual eyelid path is avoided. The method is applied to three types of database, CASIA-V1.0, CASIA-V4.0Lamp and SDUMLA-HMT. For CASIA-V1.0 the accuracies are 93.2%, 99.1% and 96.7% for detecting lower eyelid, upper eyelid and free iris and the processing times are 42 ms, 49 ms and 35 ms. For CASIA-V4.0-Lamp these accuracies are 97.6%, 98.3% and 97.8% with processing time 23 ms, 26 ms and 21 ms. For SDUMLA-HMT the accuracies are 95.1%, 95.3% and 96.92% with processing time 35 ms, 40 ms and 31 ms.

• Biometric Face Classification with the Hybridized Rough Neural Network  
  by Sasirekha Kathirvel, Thangavel K 
  Abstract: Face biometric plays a vital role to authenticate a person in a right way. Face classification is an important indexing scheme to reduce face matching time for large volumes of a database. In this paper, a hybridized approach based on Rough Set Theory (RST) and Back Propagation Neural Network (BPN) for gender classification using human face images is proposed. It involves four main parts: Pre-processing, Feature Extraction, Feature Selection and Classification. Initially, the images are converted to grayscale and then the median filter is applied to de-noise. The features have been extracted using Local Binary Pattern (LBP) method as they exploit the rich discriminatory information existing in the face images. The evolutionary optimization algorithms such as Genetic Algorithm (GA), Particle Swarm Optimization (PSO), Ant Colony Optimization (ACO), hybridization of ACO and GA (ACO-GA) and hybridization of PSO and GA (PSO-GA) are investigated for feature selection from the face. Finally, the hybridized Rough Neural Network (RNN) is employed to classify the face images. In this research, experiments have been conducted on real-time face images collected from 155 subjects each with ten orientations using Logitech WebCam and also on ORL face dataset. The experimental result of the proposed RNN is compared in terms of precision, recall, f-measure, accuracy and error rate with other benchmark classification techniques such as Naive Bayes, Support Vector Machine (SVM), Radial Basis Function Network (RBFN) conventional BPN, and Convolutional Neural Network (CNN) to conclude the efficacy of the proposed approach.

• An Improved Weber Face Based Method For Face Recognition Under Uncontrolled Illumination Conditions  
  by Boualleg AbdelHalim, Deriche Mohamed, Sedraoui Moussa 
  Abstract: This paper presents a new face recognition system robust to illumination variations and moderate occlusion. Two main contributions are discussed. First, we introduce an approach based on Contrast Equalization (CE) to improve the traditional Weberface (WF) technique and make it more robust. Second, we use the Local Binary Patterns (LBP) and Local Phase Quantization (LPQ) descriptors to make the Weberface method more resilient to extreme variations in illumination by exploiting both spatial-domain and frequency-domain information. Finally, by combining the outputs of the two descriptors, enhanced facial features are obtained which are shown to possess more discriminating power not only for variable lighting conditions but also for occlusion. Once the features are extracted, these are used with a simple Knearest neighbor classifier. The concept of using the (WF) model together with spatial and frequency domains descriptors is novel and proven to result in a robust system resilient to varying lighting conditions and small to moderate variations in pose, and moderate occlusion. The effectiveness of the method is validated and compared to many classical illumination compensation techniques over three public datasets; namely the Yale B, the extended Yale B, and the AR databases. The proposed algorithm is shown to consistently outperform existing techniques under different challenging environments.

  by Samik Chakraborty, Madhuchhanda Mitra, Saurabh Pal 
  Abstract: Ear is a potential biometric parameter which has drawn the attention due to its structural uniqueness and stability over the age, obesity, disease, expression etc. unlike other common biometric traits. In this work a geometric retrieval algorithm has been proposed for ear based biometric analysis with occluded image. First the occlusion problem is countered by an empirical data driven technique and then PSO based optimal features are extracted for comparison that reveals the authenticity of the subject with respect to a stored database. A search of minima from Euclidian distance based analysis is used for final decision. The proposed system is tested on 50 subjects collected in multiple sessions in laboratory with a good recognition rate superior to similar reported works as indicated in the result section.

  Abstract: In this paper, a quantized eigen analysis (QEA) for the extracted features is proposed and rnan associated eigen-based binary feature amalgamation (EBFA) based on QEA is developed rnfor feature fusion in multimodal biometrics. rnAs opposed to feature combination, EBFA projects heterogeneous features onto the projection kernel and rnuses only the sign parts to encode the features as bit strings to maximize its expression rnrather than directly combine them. rnThus the feature codes can be simply concatenated or compared by XOR bit-wise operation rninto a serial or parallel amalgamated feature vector. rnTo evaluate the performance of EBFA, a series of experiments are performed on rnmultiple biometric modalities, including face, palm-print and iris. rnThe experimental results show that the proposed binary feature amalgamation scheme at feature-level rnis superior to some other feature fusion methods and score-level methods in terms of multimodal recognition accuracy performance.

• LAUGHTER SIGNATURE: A NOVEL BIOMETRIC TRAIT FOR PERSON IDENTIFICATION  
  by Comfort Folorunso, Olumuyiwa Asaolu, Oluwatoyin Popoola 
  Abstract: Laughter is a naturally occurring feature in speech and social interactions. Human intelligence can identify people by their laughter, but this has not been explored as a potential biometric in person identification systems. This study proposes a novel behavioral biometric based on individual laughter signatures. Mel Frequency Cepstral Coefficients (MFCC) features were extracted and Kruskal-Wallis test was performed on each coefficient. A Dynamic-Average Mel Frequency Cepstral Coefficients (DA-MFCC) was developed from the typical MFCC features for system training using Gaussian Mixture Model (GMM) and Support Vector Machine (SVM). Test results showed an accuracy of 90%-person identification for SVM while the GMM was 65%. The use of GA-MFCC improved the accuracy of the system by 5.06% and 2.99% for GMM and SVM respectively. Laughter has thus been shown to be a viable biometric feature for person identification which can be embedded into artificial intelligence systems in diverse applications.

• Efficient Fusion of Face and Palmprint in Gabor Filtered Wigner Domain  
  by Nirmala Saini, Aloka Sinha 
  Abstract: In this paper, a new transform Gabor Filtered Wigner transform (GFWT) has been proposed. In GFWT, Gabor filtering is performed on the Wigner transformed image. Wigner transform gives a simultaneous representation of an image in time and frequency domain which is further processed using Gabor filters. The proposed transform is then used to extract the features from the biometrics to develop different multimodal biometric systems. A detailed study has been carried out in which, different unimodal and multimodal systems such as feature level and score level fusion are analysed. In order to improve the performance of the system, an optimization technique, particle swarm optimization (PSO) is used to find the optimal parameters of the Gabor filter and to select the significant GFWT feature vector. The PSO technique not only improves the performance of the system but also able to reduce the dimension of the feature vectors. Numerical experiments are carried out on face and palmprint database to show the effectiveness of the proposed transform for different unimodal and multimodal systems.

• Fingerprint pores extraction by using automatic scale selection  
  by Diwakar Agarwal, Atul Bansal 
  Abstract: Extraction of fingerprint sweat pores is a critical step in those applications which are based on highly secured features. Pores are varying in scale (size) and evenly distributed along the ridges. It is the main challenge to design a technique which determines the pores of different sizes in the fingerprint image. In this paper, pore extraction algorithm is proposed for high-resolution fingerprint images which utilized multiscale ?-normalized Laplacian of Gaussian (LoG) filter. A block-wise approach is implemented in which each region is filtered at multiple scale values. Scale space theory is applied and candidate pixels of high negative response are identified through local maxima approach. The efficacy of the proposed algorithm is tested by measuring average True Detection Rate (TDR) and average False Detection Rate (FDR). Results of the proposed algorithm achieve TDR and FDR values as 82.89% and 21.2% respectively which are better in comparison to the state-of-art techniques.

  by Liu Yongqiu 
  Abstract: AC permanent magnet synchronous motor servo control system is a complex nonlinear, strong coupling and time-varying system. It has strong uncertainty and nonlinearity, and when the system is running, it also will be disturbed to varying degrees, so the conventional control strategy is difficult to meet the control requirements of high accuracy, high speed and high-performance servo system. This paper adopts a direct feedback linearization control strategy based on sensor technology and uses w, i_das the output of the system to realize the decoupling of the system. In addition, the grey prediction is added to overcome the shortcomings of direct feedback linearization that is sensitive to parameters. Adjusting the uncertain factors block by grey prediction to adapt to the direct feedback linearization rule and achieve the desired effect. MATLAB/Simulink is used to complete the simulation of servo control algorithm. The simulation results show that the direct feedback linearization control is better than the conventional PID control, and the direct feedback linearization control algorithm with grey prediction can improve the performance of the permanent magnet synchronous motor servo control system and can meet the basic requirements of the high-performance servo control system.

• Research on Optimization of Complex Model of Large-Scale Building Structure Dependent on Adaptive Grey Genetic Algorithm  
  by Shi Xiaohong 
  Abstract: Genetic algorithm (GA) is a bionics algorithm based on the biological evolution theory that has received extensive attention in the field of computer science and Optimization in recent years. This paper analyzes and integrates the relevant contents of genetic algorithm and its application in the optimal design of large-scale building structures and analyzes and researches briefly several key factors when the genetic algorithm is applied to the optimal design of large-scale building structures, such as mathematical modeling, constraint condition treatment, generation of initial population and selection of control parameters of genetic algorithm. However, because the simple genetic algorithm is only good at global search, and the local search ability is not enough, it will take quite a long time to achieve the real optimal solution. For the shortcomings of simple genetic algorithm, an improved adaptive grey genetic algorithm is proposed in this paper. The example shows that the obtained adaptive genetic algorithm can improve the convergence and calculation speed when the genetic algorithms is applied to structural optimization design.

  by Shi Qiongyan, Zhang Jianghua 
  Abstract: The manipulator is the new artificial intelligence device, and its motion control is the basis for ensuring the stability of the manipulator's attitude. The traditional manipulator motion control adopts the static neuron control method, which will lead to small disturbance in the attitude control of the manipulator, and cause the stable motion performance of the manipulator.
