Presents the introductory welcome message from the conference proceedings. May include the conference officers' congratulations to all involved with the conference event and publication of the proceedings record.
Aiming at the problem of low speed of 3D reconstruction of indoor scenes with monocular vision, the color images and depth images of indoor scenes based on ASUS Xtion monocular vision sensor were used for 3D reconstruction. The image feature extraction using the ORB feature detection algorithm, and compared the efficiency of several kinds of classic feature detection algorithm in image matching, Ransac...
This paper proposes a novel 3D shape retrieval method for articulated shape models. The proposed method is composed of a topological matching step based on skeleton graph and a geometric matching step based on shape diameter function. In the first step, the curve skeletons of the shape models are extracted and a similarity measure based on skeleton graph is used for 3D shape retrieval. In the second...
To solve the difficulties of high calculation quantity and low precision in constructing an air transport network, the paper puts forward a kind of hybrid algorithm, which called Bayesian network model based conditional independence test and heuristic search (CIBNS, CI-based Bayesian Network Search). The new algorithm firstly makes use of the conditional independence test to compress the search space,...
With the acceleration development of the Internet of Things and big data, the importance of high-performance mass data retrieval is gradually highlighted. Cloud computing is the distributed data calculation model that is suitable for big data, and has been widely used. In this paper, firstly, the technology of cloud computing is introduced. Secondly, retrieval technology of mass data is analyzed,...
This paper presents the basic principle and application of ARIMA model, and this model is used to analyze crude oil price time series and obtain the second order linear regression model. The model is used to predict the price of crude oil. On this basis, according to the residual error after fitting the existing nonlinear ARIMA model, the fitting residual error is analyzed by using the artificial...
Web data mining technology can effectively improve the network information security, and gradually it has become a core technology to strengthen network information security. Based on the author's work and learning experience, this paper firstly analyzed the value of Web data mining technology in network information security, and then discussed a network information security model based on Web data...
In order to meet the demand of physical properties in complex environment, new tactile sensors are designed, which based on cascaded fiber gratings. In this paper, A New Method for the Analysis of Cascaded Fiber Bragg Gratings Applied to Tactile Sensors is proposed, The calculation results of the numerical simulation demonstrate that the spectrum of the cascade grating groups is basically the superposition...
Credit risk management has been one of the most serious problems for banks and other financial institutions. With the continuous improvement of the economic system reform of our country, the establishment of market mechanism and perfect, the rapid development of capital markets and the banking sector, the existing credit evaluation system and method have been unable to keep up with the needs of the...
This paper puts forward a new tracking algorithm based on Mean Shift algorithm and the Particle Filter algorithm. We combined the two algorithms efficiently based on the open structure system of both Mean Shift algorithm and the Particle Filter algorithm, and the model similar expression of establishment of the target, similarity measure and the selection of kernel function they have. The new algorithm...
Internet-based self-learning has become one of the important ways in learning, it is also a kind of lifelong learning ability. Internet-based supporting factors which including four key factors, namely knowledge internalization supporting factors, mission supporting factors and peer supporting factors and social supporting factors, which has different impact on college English self-learning. English...
The data file's format of 3D model generated by GoCAD is researched, and a 3D Visualization System for GoCAD objects is developped based on VTK visualization graphics library and QT platform. It can load the pointset, curve, surface files exported from GoCAD model into true 3D render window, suplies tools for geologists to analise the geological model. It is more convinient to view and analise the...
