Phase images derived from imaging devices are usually wrapped into discontinuous images, so phase unwrapping is needed for phase image reconstruction. The wrap counts of every voxel are determined by the assumption that the true phase is spatially continuous. However, it is difficult to distinguish whether the phase jump is caused by phase wrap or noise. In this paper, a new 3D phase unwrapping method...
Meta search engine is an effective tool for searching information online. In comparison with independent search engine like Google, Bing, and etc., meta search engine has a wider coverage and can meet the requirement of information retrieval in a better manner. In particular, when a query is received from the user, the meta search engine sends it to some proper candidate member engines, collects results...
Information technology has been advancing in many countries. In their daily lives, people encounter computerized systems in many situations and often take their operation for granted. If a system failure occurs temporarily, it is disadvantageous for the system operator and the user. The use of distributed and parallel processing systems has increased the prevalence of software failures due to resource...
Dynamic symbolic execution (DSE) is widely used to generate test cases for automated test. However, the practicability of DSE is greatly decreased by path explosion, which is an unavoidable challenge caused by that the number of execution paths increases exponentially with the increase in the size of program. To alleviate this problem, dynamic symbolic execution based on multiple test points (MPDSE)...
The design of 3D scene should follow the rules of architecture's organization. At present, the 3D scene design are usually carried out by art designer who lack the knowledge of architecture. A method is proposed in this paper to solve the problem. We improved the interactive genetic algorithm to obtain the best adaptive features, and combined the ART1 network to simulate the behavior of users to evaluate...
Combine the connotation of college student's entrepreneurial risk to specifically elaborate the type of college student's entrepreneurial risk and avoidance strategies, and then based on the current situation of their risk awareness, propose suggestions and countermeasures of combining practice with class theories to improve college student's entrepreneurial risk awareness.
Flexible job-shop scheduling problem (FJSP) is an extended job-shop scheduling problem. FJSP allows an operation to be processed by several different machines. FJSP with overlapping in operations means that each operation is divided into several sublots. Sublots are processed and transferred separately without waiting for the entire operation to be processed. In previous research, a mathematical model...
The video segmentation is the basis of video analysis and digging, the results directly affect the accuracy of follow-up processing. For the video segmentation, the predecessors have done a IoT of research. We have achieved very good results in regard to the mutant lens, but there is no good way for the gradient. Because football is a popular sports, it has a very practical significance for the process...
Film data analysis is important for website to find relationship between film data. Other than normal relational database, a novel and popular graph database, Neo4j uses graph related concepts to describe data models, the data can easily be nodes, edges and their associated attributes. By focusing on film data, Neo4j-based analysis is conducted in this paper. Firstly, Neo4j and Cypher Query Language...
The present paper concerns itself with a theoretical calculation study on implementation and optimization of protein sequence issue. Using ant colony optimization algorithm (ACO) to build the Two-Dimensional Hydrophobic-Hydrophilic (2DHP) model. There are three parts in this paper. Starting with a brief introduction of the ant colony optimization and 2DHP model, then we propose a method on how to...
Aiming at the functional requirements of the Express Supervision System, This paper discusses the advantages of using AngularJS to build the front-end framework, the advantages of using NodeJS to construct the back-end Web server, and the performance advantages of storing data based on MongoDB. This paper focuses on the storage solutions of using MongoDB to store large data and the statistical analysis...
With the development of computer and network techniques, and the digital Chinese news texts explosion, facing a massive unstructured news data, a better way for knowledge extraction and storage, on the one hand, can help readers understand the core content of news, on the other hand, completed news knowledge accumulation will support the reportage. In recent years, information extraction technology...
This paper mainly talks about the Recurrent Neural Network and introduces a more effective neural network model named LSTM. Then, the paper recommends a special language model based on Recurrent Neural Network. With the help of LSTM and RNN language models, program can predict the next character after a certain character. The main purpose of this paper is to compare the LSTM model with the standard...
Digital cameras are widely used in desktop and notebook PCs. Taking self-portraits is one of the important function of such cameras, which allows users to capture memories, create art, and improve photography techniques. A desktop environment with a large display and a pan-and-tilt camera provides users with a good area for exploring more angles and postures while taking self-portraits. However, most...
Machinima is which use real-time graphics rendering platform game engine to create animated videos or films. Traditional methods of machinima filming are stand-alone methods that using artificial intelligence scripting to implement the plot. However, massive script writing work of artificial intelligence will cost a IoT of manpower and resources. This paper proposes a method based on network game...
Ordinary Fluid Simulation focuses on the effects of the fluid surface, like seas, rivers and lakes, which is massive and unshakable. Few researches have devoted to simulate the phenomenon of fluid in containers, especially the behaviors of contained fluid being moved or tilted. This paper concentrates on dynamic simulation of fluid in containers. Based on Unity3D and Smoothed Particle Hydrodynamics...
Based on related statistical data about Chinese cultural consumption, this paper analyzes and compares the regional differences of it in China in the environment, level and tendency of cultural consumption by establishing statistical models, and explores the main influencing factors in different regions. Finally this paper puts forward some policies and suggestions according to the results to elevate...
To provide immersive freehand painting experience, we proposed a flexible airbrush model making use of the hands tracking capability of Leap Motion Controller. The airbrush model uses a common screen as the painting canvas. When the user moves hands over the screen, the brush model continually acquires his/her hands movement data and extracts multiple control signals which describes multiple gestures...
AdaBoost is a classic ensemble learning algorithm with good classifier performance. In the past, it mainly used weak classifier as base classifier, such as KNN. They are simple and easy to train, but the essence of the weak classifier, it is impossible to get very high classification accuracy. In order to improve the correct rate, this paper introduces the AdaBoost ensemble classifier based on convolutional...
