Abstract: In this study, an important geometric transformation, multidimensional color image scaling based on an n-qubit normal arbitrary superposition state (NASS), is put forward. In order to reduce the complexity of implementation of image scaling in a quantum system, nearest neighbor interpolation algorithm is chosen to implement image scaling up. And the corresponding quantum circuit of implementation is proposed. Finally, we discuss measurements of the part qubits of a NASS state to realize image scaling down. The paper explores theoretical and practical aspects of image processing on a quantum computer.

Abstract: To solve lane detection problem in the system of autonomous vehicle, this paper proposes a method of texture segment based on perspective transformation. In this paper, firstly road images were captured through cameras installed on the vehicle, then make a perspective transform to road plane, so that the road and the non-road texture information effectively stand out. After calculation of the texture trend in the transformed image, radon transform can effectively distinguish between the road and the non-road area, and achieve the purpose of the texture regional segment. Experiments prove that this method can be used on the lane detection, which eliminate barriers and road borders effectively.

Abstract: The aim of unstructured road detection is the recognition of road region and the tracking of road boundary. An improved Otsu threshold method available in double-threshold segmentation was proposed in this paper to resolve the multi-peaks problem in both complicated background and target. This method remedies the mis-segmentation of Otsu threshold method caused by huge diversity of between-class variances and refines the segmentation precision by matching the proposed Otsu edges with the weighted Canny edges. According to the irregular characteristics of the unstructured road and the requirement of the real-time motion planning for intelligent vehicle, improved Otsu threshold method was proposed. The experiment results in different road environments demonstrated the validity and real-time of the proposed method.

Abstract: The ceramic industry fall into two main categories: daily used ceramics and craft ceramic. With the demand for daily used ceramics is increasing in my country, ceramics enterprises are faced with intense market competition. Based on the investigation of ceramic industrial production, the traditional method for Ceramic production has some disadvantages, such as long periods of dies production, complicated production process, wasting human resource, high cost, short life, poor quality, easy to damage. According to the characteristics of daily used ceramics, this paper presents a rapid prototyping system based on RS-232C compacts. This system can cancel the long and complex development process of the dies, and can achieve rapid prototyping of ceramic body, thereby greatly reducing the cost of production of ceramic manufacturers.

Abstract: The collection of light field is a key part of 3D image rendering and multi-view display system construction. Data exchange of light field frequently used in light field camera array requires high real-time performance and high bandwidth. This paper presents a new method of light field data exchange by applying data distribution service (DDS). Experiment results show it is feasible to apply data distribution service to the light field camera array.

Abstract: The traditional class naming is take time, the effect is not good, and there will be many take another's place by counterfeiting phenomenon, So, this paper proposes a random naming system based on image processing. This paper establishes the database class students, including students some basic information, such as name, student number, photos; then establishes a random roll call system, which the teacher can random name evaluation, for students grades and attendance; finally, test system and further improve . Because the roll call to show the students the image clear based on image processing , avoid take another’s place by counterfeiting phenomenon, student performance improved significantly. The test results show that the random naming system we developed, convenient for teacher to student's attendance and can improve student the attendance.

Abstract: With the rapid development of Internet technology and information technology, the emergence of a large number of document data, text classification techniques for handling massive amounts of data is becoming increasingly important. This paper presents a distributed text feature extraction method based on distributed computing model—MapReduce. In the process of mass text processing, solve the problem of processing text size limit and inadequate performance, provide the research of text feature extraction method a new way of thinking.

Abstract: This paper targets on the existing problems in the University Human Resource Systems such as equipment scattered, utilization lower and difficult to share data etc. It proposes Virtualization Technology achieve maximum results to solve the problems with a minimum of manpower and financial cost. Virtualized servers can make equipment concentration and high utilization. It establishes virtualized interface to share data and meet the needs of various departments’ on-demand services. Moreover it can centralize management of data backup and security.

Abstract: Along with the popularization of computer and network in all aspects of people’s social life and the combination of computer technology with communication technology, here comes a new information age and network times. People’s need of information characterizes multiple levels and diversity. University library as the information center has to speed up the construction on the automation and digitization of network in order to offer high-quality and high-efficiency information service to meet the readers’ demand of individual information.The principle purpose of information construction of university library is to mine, acquire and spread knowledge to the utmost extent, to provide a platform for readers to share information and to offer them the best service.

Abstract: The basic RTPS implementation for discovery protocol need to waste a lot of memory space and network traffic. SDPBloommake use of Bloom Filter to reduce the memory requirement and network load in thediscovery process,but it can not deal withthe scenarios that many Endpoints with common Topics but with heterogeneous andincompatible QoS settings. To solve the problem,this paper propose a improved discoveryprotocol called SDPBloom_QoS. SDPBloom_QoS give a method that can put QoSinformation into Bloom Filter. Then provide both analytical andexperimental studies. Results show that SDPBloom_QoSis more powerful than SDPBloom.
