Dunhuang mural images classification belongs to the research task in the field of image recognition. In this paper, the semi-supervised model is established with multidimensional features extracted by transfer learning. A small number of labeled samples were used to obtain a large number of unlabeled data, combined with Active Learning and iterative strategy for multiple rounds of label transfer of selected samples. After several rounds of iterations, we can get a more powerful classification learner. Experiments on the self-built Dunhuang mural dataset have shown that the results can approach or even exceed some supervised learning methods when the number of known label samples is less than 4%. Our research implements the cultural resource image classification algorithm based on small samples, which is conductive to improving the accuracy when label samples are scarce. © 2023 IEEE.

This paper explores the key technologies for fast conversion in small-sized cultural complex. For the complexity and uncertainty of the building space, a flexible methodology of multi-AGV collaborative operation is introduced to transfer the functional equipment. It is supposed to be disassembled and reconstructed in different environments. In order to solve the scheduling problem of multi-task AGV system joint operations in this complex working environment, this paper proposes three branches; AGV path planning study, multi-task scheduling study, and conflict avoidance study in collaborative work. For those three research fields, this paper explores its related constraints and establish a research framework for fast device transfer technology within the multi-functional small-sized cultural complex. This work will lay the technical foundation for fast conversion of functional equipment.

The oral story culture of ethnic folklore is one of the important components of traditional Chinese culture, and it is of key importance to study the timbre evaluation methods of this type of audio after digital capture. This paper uses subjective timbre evaluation experiments to explore the subjective perceptual characteristics of audio signals of oral story, extracts the objective acoustic parameters of audio timbre based on human vocal principles, auditory perceptual characteristics and speech time domain features, and conducts research on objective timbre evaluation methods based on support vector regression (SVR), random forest regression (RFR), convolutional neural networks (CNN) and long short-term memory networks (LSTM). The results show that the use of feature extraction and non-linear algorithms has good results in the evaluation of oral story timbre. © 2023 IEEE.

International Conference on Computer and Information Science (ACIS)

作者： Hui Ren Yang Liu Huiqin Wang Key Laboratory of Acoustic Visual Technology and Intelligent Control System Ministry of Culture Communication University of China Beijing China

The OPC UA standard overcomes many disadvantages of the traditional OPC, and has significant advantages in platform independence, communication security and model construction, thus completing the information exchange under different platforms and interfaces. At present, the automation system equipment has the problems of complex protocols and interfaces and poor portability of industrial computer. To solve this problem, this paper develops the ARM embedded OPC UA client to complete the data communication with the automation system device server by porting the open62541 open source library on the ARM embedded device equipped with the FreeRTOS system. In this research, by building the OPC UA client on the embedded system, the connection and communication with the server are realized, which is also cheap and flexible to use. Experiments show that the system can be used in equipment debugging, field operation and emergency control, and has a wide range of application prospects and practical value.

Effect of Colored Content on Depth Perception of S3D Images

Effect of Colored Content on Depth Perception of S3D Images

International Conference on Computer and Information Science (ACIS)

作者： Zhi-bin Su Ya-nan Su Yi-han Suo Hui Ren Ministry of Culture and Tourism Key Laboratory of Acoustic Visual Technology and Intelligent Control System(Communication University of China) Beijing China

This paper has mainly focused on the depth perception effects and the influence factor of hue for colored content of stereoscopic 3D (S3D) images. The subjective evaluation experiment was designed with different color combinations of foreground object and background. Through the data analysis, the hue of background was proved to be a significant indicator for certain colored foreground content with negative disparity. For most of the contents designed with positive disparity, the effect of background hue was not obvious. To get better effect of space sense, for all of the foreground colors with either positive or negative disparity, black can get the higher rating results than any other colors. Besides, appropriate color combination could bring idea stereo experience for observers. Our studies have practical significance and reference value to improve viewing experience and relative objective models for the S3D image and videos.

Text Categorization plays an important role in the fields of information retrieval, machine learning, natural language processing, data mining and others. With the development of computer and information technology, there have been many classification algorithms. Each text classification algorithms will get result at differing speeds and efficiency due to the various feature of test text. It has been found that Naive Bayes classifier has a higher accuracy and rate by classifying Movie Reviews in NLTK using Decision Tree classifier, Naive Bayes classifier, Maximum Entropy classifier and K-nearest neighbor classifier.

The evaluation system of the theater is based on user data, professional evaluation and audience comments, and we use web technology to build the system. In this paper, the framework, function and technical design of the evaluation system of the theatre are presented. Thebootstrap is used to buildthe framework. Apache and My SQL are used in the server *** a variety of technical methods, we ultimately can establish a theater evaluation system which has the functions of user classification, grading, information browsing and management.

At present, manage systems for entertainment performance chains are built to work as agents to collaborate all participants, such as troupes, theatres and audience etc. Analyzing and mining the mechanism of behaviors of participants is an important issue which can be important gudie to establish such manage systems. On the basis of analyzing troupes' interactive process with audience and theatre, this paper constructed a Stochastic Petri Net(SPN) model for describing the behaviors of two troupes. Furthermore, average time delay was chosen as the performance index to evaluate the performance of the model with Stochastic Petri Net Package(SPNP) 6.0. For different parameters of number of presentations, size of theatre space, space requirements, various trends and numerical results are derived thereby. The methodology of modeling and simulation in this paper can be further used to study the performance of manage systems for entertainment performance chains.
