TL;DR: The MATLAB simulation results show that the gray level co-occurrence matrix generated by the four texture features can effectively describe the texture characteristics of wood with good differentiation.
Abstract: Widespread in nature Texture,texture is the most essential properties of the surface Texture analysis has been a hotspot in research As the primary task of texture analysis,texture feature extraction is the focus of study This paper puts forward a texture features extraction method for the five kinds of wood grain with the gray level co-occurrence matrix The MATLAB simulation results show that the gray level co-occurrence matrix generated by the four texture features can effectively describe the texture characteristics of wood with good differentiation

TL;DR: Through this experiment, it is proved unity3d is a very useful tool for designing a virtual platform.
Abstract: The campus virtual roaming system is the important content of the university information system development strategy,the virtual roaming system is applied in every field of our lives.Take a college as virtual space,the system based on Unity3D platform is constructed by using 3Dmax to build the scene,taking JavaScript and C# as the programming tool to implement the function of interaction.Through the integration with html,the virtual campus is established.This system has three-dimensional navigation function and good interactive experience.It is convenient for consumers to require information about the college.Through this experiment,it is proved unity3d is a very useful tool for designing a virtual platform.

TL;DR: According to the actual needs of intelligent household, environmental monitoring etc, this paper designed a wireless sensor node of long-distance communication system and has given the hardware design schematic diagram and the software flow chart of sensor node,synchronizer node.
Abstract: According to the actual needs of intelligent household,environmental monitoring etc,this paper designed a wireless sensor node of long-distance communication system.This system used the second SoC CC2530 set in RF and controller chips as the core module and externally connected with CC2591 RF front-end power amplifier module.Based on ZigBee2006 in software agreement stack,it realized each application layer function based on ZStack.It also introduced wireless data acquisition networks based on the ZigBee agreement construction,and has given the hardware design schematic diagram and the software flow chart of sensor node,synchronizer node.The experiment proved that the node is good in performance and the communication is reliable.The communication distance has increased obviously compared with the first generation TI product.

TL;DR: In this paper, video segmentation strategy on distributed storage and how they affect accessing time are discussed and metadata of video formats and transcoding parameters are defined.
Abstract: Based on study of current video transcoding solutions,we proposed a distributed transcoding system.Video resources are stored in HDFS(Hadoop Distributed File System) and transcoded by MapReduce program using FFMPEG.In this paper,video segmentation strategy on distributed storage and how they affect accessing time are discussed.We also defined metadata of video formats and transcoding parameters.The distributed transcoding framework is proposed on basis of MapReduce programming model.Segmented source videos are transcoding in map tasks and merged into target video in reduce task.Experimental results show that transcoding time is dependent on segmentation size and trascoding cluster size.Compared with single PC,the proposed distributed video transcoding system implemented on 8 PCs can decrease about 80% of the transcoding time.

TL;DR: This paper puts forward the synthesis,similarity operation and realizes comprehensive evaluation and decision-making based on trust classification and shows that the trust evaluation model proposed is valid.
Abstract: To solve the problem of the transaction security in C2C e-commerce,this paper proposes an evaluation model based on cloud model theoryThe created definition of the trust cloud and the standard cloud in the valuation model show the ambiguity and random of the trust and realize transferring quantitative data to qualitative dataThis paper puts forward the synthesis,similarity operation and realizes comprehensive evaluation and decision-making based on trust classificationThe results of experiments show that the trust evaluation model proposed is valid
