Contactless palmprint recognition systems alleviate the concerns on personal hygiene, acquisition flexibility, etc. Unfortunately, the preprocessing of contactless palmprint image faces several severe challenges, including unconstrained hand placement, complex background, light interference, etc. This paper proposes logical conjunction of triple-perpendicular-directional translation residual (TPDTR)...
This paper proposed a new image inpainting method based on morphological component analysis that is capable of filling in holes in overlapping texture and cartoon layers. Firstly, due to rich content and complex color of Tangka image, the imposition of a total variation penalty by conventional model may not be accurate and easy to produce staircase. To improve the performance of sparse-representation-based...
Multi-modal biometrics enjoy more merits than their single-modal counterparts in terms of accuracy performance and security. The fusion of hand-based biometrics such as palmprint and palmvein is straightforward since they can be acquired simultaneously with a customized image acquisition device. Conjugate 2DPalmHash Code (CTDPHC), which is constructed by 2DPalmHash Codes (2DPHCs) of palmprint and...
In Singapore Primary Schools, Singapore History is integrated with Geography, Economics and Sociological principles, and offered as a Social Science subject. Singapore History Alive with 3D! is a comprehensive multimedia teaching and learning package developed by IM Innovations in 2011 to enhance the teaching and learning of Singapore History for Primary Four students. Upon entering the immersive...
To keep the balance between the global search and local search, a novel binary quantum-behaved particle swarm optimization algorithm with comprehensive learning and cooperative approach (CCBQPSO) is presented. In the proposed algorithm, all the particles' personal best position can participate in updating the local attractor firstly. Then all the particles' previous personal best position and swarm's...
To achieve a minimal time to through the urban traffic trunk road. However, the traditional analytical algorithm can not be applied in actual traffic widely. By combining the genetic BP neural network with the traditional analytical, A novel dynamic two-direction green wave coordinate control strategy was proposed, which applied in solving the function optimization problem. Finally, the new algorithm...
Under the background of the balance of exploration and exploitation, this paper analyzes the causes of the optimization hardness by using the concepts of effective ratio of exploration and exploitation. Then, a novel method is proposed to estimate the optimal feature factor, which is the essential part of optimal contraction theorem. At last, the method is tested with eight test functions. Some disadvantages...
Recently two-dimensional (2D) Palm Hash Code was proposed as a cancelable palm print coding scheme for secure palm print verification. However, there is vertical correlation between the vertically adjacent entries of 2DPalmHash Code. Armed with the statistical correlation analysis, an attacker can break into the palm print verification system easier than using brute-force attack. This paper analyzes...
In this paper, an improved intersection detection method is proposed by applying the VCS-based algorithm on the registered scans instead of the single scan. Both the registration and intersection detection approach are independent on Global Positioning System (GPS), Geographic Information System (GIS), Inertial Navigation System (INS) or other auxiliaries which have been extensively used in autonomous...
The formation and growth of intermetallic compounds of Sn-2.0Ag-2.5Zn solder on Cu and Ni substrates after soldering and subsequent aging process have been investigated in this study. Ni films were electrodeposited on copper substrates. The interfacial micrographs of solder joints prepared at 250°C for 15s and aged for 24h, 96h and 216 h respectively. Double-layer IMC composed with Cu5Zn8 and Ag3Sn...
An ideal low temperature bonding method was studied. Cu cones were prepared by electroless plating. Heating and pressure were used in the bonding process between Cu cones and Sn-3.0Ag-0.5Cu solder. It's a solid state bonding method because the bonding process was performed below the melting point of solder. Shear strength was measured by bonding tester. Morphologies of Cu cones, fracture surfaces...
According to The Program Evaluation Standards (1994) published by The Joint Committee on Standards for Educational Evaluation (JCSEE), this study performs a meta-evaluation on the teaching feedback questionnaire (Appendix I) of Ming Chuan University (MCU), Taiwan, through questionnaire analysis in terms of the appropriateness and the indication of the questionnaire items. The participants of this...
A co-design scheme of static period quantized scheduling and the state feedback controller for a class of networked control system with limited bandwidth and fixed time delay using mid-tread uniform quantizers is proposed in this paper. Through allocating bandwidth, the quantized scheduling strategy and feedback controller design are considered simultaneously. The quantized measurement signals are...
Finding road intersections in advance is crucial for navigation and path planning of moving autonomous vehicles, especially when there is no position or geographic auxiliary information available. In this paper, we investigate the use of a 3D point cloud based solution for intersection and road segment classification in front of an autonomous vehicle. It is based on the analysis of the features from...
Traditional methods of generating test data may result in redundancy of test data, which brings many troubles to software testing. In order to solve the redundancy of test data, this study proposed a novel approach of generating test data by reducing target statements based on dominant relations. First, basic concepts and principles concerning dominance are listed. Then, an approach is proposed to...
High precision DSSC control in D-FACTS is discussed in the paper. A triple-loop control method is proposed with Proportion-Resonance AC output voltage controller aimed to gain high precision compensation voltage. In order to provide a clear control object to the DC voltage controller design, a DC voltage control idea is proposed, which transformed the DC voltage control to AC output voltage reference...
Interactive genetic algorithms (IGAs) are effective methods of solving optimization problems with qualitative indices. The problem of user fatigue resulting from his/her evaluations, however, restricts their applications in complex optimization problems. Employing various surrogate models to evaluate (a part of) individuals instead of a user is a feasible approach to solving the above problem. Previous...
Fuzzy clustering analysis is a widely used fuzzy mathematics method ,which could be applied in various fields. Based on the fuzzy set theory, application of fuzzy clustering analysis in microbial enhanced oil recovery (MEOR) was studied. At first, strains which had ability to produce biosurfactant were selected as part of the statistical indicators. Then data were corrected and standardized by empirical...
