Nowadays, the attacks on the Internet are becoming more complex, advanced and concealed. A large number of security threats arise. The signature-based detection technology is efficient and simple which is widely used for malicious codes detection system. In this paper, we firstly focus on the principle of the method, and summarize the specific steps to implement it, especially feature extraction,...
In this paper, a facial expression recognition algorithm based on Gabor and conditional random fields is proposed. Firstly, owing to the fact that in the existing databases, the number of people and images are relatively small, we established our own facial expression database, and some preprocessing methods are performed thereon. Secondly, Gabor features are extracted in five scales and eight directions...
Reconstructing 3D face models from multiple uncalibrated 2D face images is usually done by using a single reference 3D face model or some gender/ethnicity-specific 3D face models. However, different persons, even those of the same gender or ethnicity, usually have significantly different faces in terms of their overall appearance, which forms the base of person recognition using faces. Consequently,...
Identical twins pose an interesting challenge for recognition systems due to their similar appearance. Although various biometrics have been proposed for the problem, existing works are quite limited due to the difficulty of obtaining a twins database. To encourage the methods for twins recognition and make a fair comparison of them by using the same database, we collected an audio-visual twins database...
According to the existing problems in the WLAN fingerprint positioning technology and wireless signal propagation characteristics under indoor environment, this paper proposes an indoor location method with better rapidity, better self-adaptation and higher positioning accuracy. WLAN fingerprint positioning method is improved from three aspects in this article: first of all, by multi-fingerprints...
According to the existing problems in the WLAN fingerprint positioning technology and wireless signal propagation characteristics under indoor environment, this paper proposes a indoor location method with better rapidity and higher positioning accuracy. WLAN fingerprint positioning method is improved from three aspects in this article: first of all, through Kalman filtering, the data of signal fingerprints...
Depth map super resolution from multi-view depth or color images has long been explored. Multi-view stereo methods produce fine details at texture areas, and depth recordings would compensate when stereo doesn't work, e.g. at non-texture regions. However, resolution of depth maps from depth sensors are rather low. Our objective is to produce a high-res depth map by fusing different sensors from multiple...
Electrical energy, as a major source energy of production and life, plays an important role in national economic development. In recent years, the demand of electrical energy is increasing, the shortage of electrical energy becomes serious. In order to alleviate this problem, people has proposed the idea of load identification. Load identification system can determine the type of the load, provide...
In recent years, disastrous earthquake assault the human frequently. The evaluation and estimate of the loss and damage in seismic disaster is an important factor for earthquake emergence and post-earthquake reconstruction decision-making. This paper synthetically designs a set of disaster real-time evaluation system based on the seismic networking of things. This paper firstly collects real-time...
Based on Pro / E as the development platform, using Access to establish a database, developing Visual C++6.0 to drive the intelligent design system of spindle box. The system has finished to knowledge base establishment, database, and inference engine for tapping class spindle box, so it can finish human-computer interaction in the design of the transmission system. It can complete the design of the...
Due to complexity, multiplicity and randomness of table tennis matches, it is necessary to develop some skill and tactic diagnostic models especially an efficient scoring model to get some skill and tactics data for table tennis matches. A scoring model is developed for table tennis matches based on video image processing technology. An input match video is used to analysis the skill and tactic of...
In order to meet the educating and training requirements of tactical communication network (TCN), one advanced means is to develop its simulative training system. Firstly, the general framework of TCN simulative training system was designed, which included the system constitution, software structure and application manner. Secondly, a single federation and multi federation architecture were proposed,...
By introducing status and progress of data mining and analyzing characteristics of medical data, a mathematical model of clinical medicine data mining is designed using data preprocessing, artificial neural network and manifold learning, focusing on data mining of clinical biochemical examining results for high-risk population with cancer and cardiovascular disease, and taking model output whose input...
Raw gene expression data and amino acid metabolic pathway of Saccharomyces cerevisiae were excavated by SMD (Stanford Microarray Database) and KEGG (Kyoto Encyclopedia of Genes and Genomes), respectively. The methionine and cysteine nutritional metabolic modules were selected and analyzed, expecting to establish the relationship between the modules, and find out the important genes, which made predominant...
An heterogeneous distributed system using middleware to finish the visit to each other between P2P and Web Service system is brought forward, and the safety and veracity of visit the service must be ensured. The blue print of middleware is to adding the function of visit Web Service onto the basic function of peer. The middleware provides the service accepting and disposal of request to the Web Service,...
Passenger line flow in China is so huge that current ticketing systems cannot be viewed optimistic. After pointing out the disadvantages of existing telephone and web network ticketing systems and further comparing barcode, two-dimensional barcode and RFID(Radio Frequency Identification), this paper proposed a new ticketing system based on C/S architecture and two-dimensional(2-D) barcode on mobile...
The design of question database is an important part of digitized campus construction. In this article, the current problems which has been existed in present intelligent strategies of test paper generating was analyzed, a new model of intelligent test paper was proposed. A new strategy of intelligently generation of test paper was used in this thesis. In order to identify the questions, barcode was...
Data as a Service (DaaS) emerges as a new trend for exchanging data between independent data owners and data users so that data can be acquired on demand through standard protocols across heterogeneous platforms. It is usually a user-interactive and iterative process to compose the services into various data-driven business scenarios of data acquisition, analysis, and other processing activities....
M-learning is short for mobile learning, that takes place with the help of mobile devices to access course materials everywhere and at anytime; In order resolve the problem of storage and transmission of course materials in field of M-learning, mobile database technology was introduced. However, new features such as mobility, disconnection, heterogeneity and distribution of the mobile devices make...
PHP is one of the leading Web development languages, however, the development model of existing PHP organizes without a structure, which mixes the code of data access, the processing of business logic , and Web presentation layer together, as a relult, it brought about many problems in the Web applications , meanwhile, it could not meet the rapid development of Web apply any more. In this paper, a...
