One of the main features that distinguishes the cloud computing from the other computing models is the ability to dynamically scale resources for users as needed. However, allocating resources in the cloud is not instantaneous; it takes several minutes for a virtual instance to be initialized. The obvious solution to this issue is to predict the future need of computing resources and allocate them before being requested. In this paper, we present a workload forecasting model based on the Autoregressive Moving Average (ARMA) model for both Gaussian and non-Gaussian processes. In the proposed method, the technique of Higher Order Statistics (HOS) is used in conjunction with the ARMA model to identify the appropriate forecasting model in case of Gaussian and non-Gaussian processes. Results of experiments show the efficiency of the proposed method compared to the traditional ARMA model.
将云计算与其他计算模型区分开来的主要特性之一是能够根据需要为用户动态扩展资源。然而,在云中分配资源并不是即时的;初始化虚拟实例需要几分钟的时间。解决这个问题最明显的方法是预测未来对计算资源的需求,并在请求之前进行分配。在本文中,我们提出了一个基于自回归移动平均(ARMA)模型的工作量预测模型,该模型适用于高斯和非高斯过程。该方法将高阶统计量(HOS)技术与ARMA模型相结合,在高斯和非高斯过程中确定合适的预测模型。实验结果表明,与传统的ARMA模型相比,该方法是有效的。

Augmented reality goes beyond its description as a mere technology to a concept that sums up the convergence of multiple software and hardware technologies that are associated to enhance our vision of the world. The marriage of such a concept in its panoramic context with tourism has led to remarkable results. In this article, we present the modeling and implementation of a prototype of an Android mobile augmented reality application to serve as an electronic pocket guide to make visiting the medina of Fez even more attractive and informative. Replacing the database of specific historical monuments is sufficient to adapt the application to other cities.

Effective Speaker Identification System (SIS) involves extracting features effectively. In this paper, we propose a feature extraction scheme based on wavelet analysis which is used along with short-term features. To overcome the drawbacks of Discrete Wavelet Transform (DWT), we propose to combine Stationary Wavelet Transform (SWT) with Mel-Frequency Cepstral Coefficient (MFCC) features. The combined features were used as inputs to K-nearest neighbors (Knn) classifier. The effectiveness of the proposed method is investigated for closed-set text-independent SIS in clean and noisy environments. The experimental results indicated that the proposed approach can achieve better identification rate performance with feature extraction using SWT rather than DWT.
有效的说话人识别系统(SIS)涉及到特征的有效提取。本文提出了一种基于小波分析的特征提取方案,该方案与短期特征结合使用。为了克服离散小波变换(DWT)的缺点,提出将平稳小波变换(SWT)与mel -频率倒谱系数(MFCC)特征相结合。将组合的特征作为k近邻(Knn)分类器的输入。研究了该方法在清洁和噪声环境下的闭集文本无关SIS的有效性。实验结果表明,基于小波变换的特征提取比基于小波变换的特征提取具有更好的识别率。

Extracting the contents of a digital image has been proven a hard problem for computers. Since for them, an image is only a matrix of values, knowing what structures a human would recognize in this image, is a nontrivial problem. In this paper, we have implemented and tested a system of detection of road signs. The approach taken in this work consists of using convolutional neural network where this network is supposed to distinguish between different classes of signs (stop, attention etc.) and the final model will then be integrated to the autonomous cars. Tests carried out on the dataset GTSRB (The German Traffic Sign Recognition Benchmark) shows the performance of the system currently being developed.
对计算机来说,提取数字图像的内容已被证明是一个难题。因为对他们来说,图像只是一个值的矩阵,知道人类会在这个图像中识别出什么结构,是一个重要的问题。在本文中,我们实现并测试了一个道路标志检测系统。在这项工作中采用的方法包括使用卷积神经网络,该网络应该区分不同类别的标志(停止,注意等),然后最终模型将集成到自动驾驶汽车中。在数据集GTSRB(德国交通标志识别基准)上进行的测试显示了当前正在开发的系统的性能。

Clustering is the task of dividing data objects into meaningful groups named as clusters such that objects in the same cluster are similar and objects form different clusters are dissimilar. It is an important unsupervised technique more and more frequently adopted by several research communities. In this paper we introduce an enhanced kernel-based method for data transformation. The method is founded on the maximum entropy principle through the kernel entropy principal component analysis. Incorporating the kernel method, the input space can be implicitly mapped into a high-dimensional feature space. Therefore the nonlinear patterns turn linear. The key measure is Shannon's entropy estimated via the inertia provided by the contribution of each object in data. As a result, the proposed method uses kernel mapping function to map data before performing entropy principal component analysis. Then data could be reduced into lower dimension of valuable extracted features. This has a major effect on the fast search of center clusters based on the local densities. The method performs very well our clustering algorithm.
聚类的任务是将数据对象划分为有意义的组,称为集群,使同一集群中的对象相似,不同集群中的对象不相似。它是一种重要的无监督技术,越来越多地被一些研究团体所采用。本文介绍了一种增强的基于核的数据转换方法。该方法通过核熵主成分分析,建立在最大熵原理的基础上。结合核方法,可以将输入空间隐式映射到高维特征空间中。因此,非线性模式变成线性。关键的度量是香农熵,它是通过数据中每个对象的贡献所提供的惯性来估计的。因此,该方法在进行熵主成分分析之前,先使用核映射函数对数据进行映射。然后将数据降维为提取出的有价值的特征。这对基于局部密度的中心簇的快速搜索有重要影响。该方法可以很好地执行我们的聚类算法。

Digital Image Processing (DIP) plays a vital role in the analysis and interpretation of remotely sensed data. It forms core research area within engineering and computer science disciplines too. This paper describes a proposal design for image processing in Verilog and that can be applied for any format of images like jpg, gif, bmp etc. The main advantage of using Verilog to simulate DIP of any logical inputs is related with the possibility of an immediate FPGA based hardware implementation. Our algorithm is designed in Verilog and simulated using the Matlab and Modelsim. In fact, the input image is converted to text/pixel using Matlab and results are stored in a new text file. Using Verilog with test bench program, the inputs, outputs and memory locations are assigned in the form of text file. Then, the output texts file back to image after a conversion step using Matlab. A comparative study between HDLs Simulation and Matlab are conducted. Obtained results show well the efficiency of the proposed design. As an extension of this work, we aim to implement an efficient FPGA based hardware design for a set of image processing, enhancement, and filtering algorithms.

A new dense omnidirectional stereo matching approach 一种新的密集全向立体匹配方法
Pub Date : 2018-04-01 DOI: 10.1109/ISACV.2018.8354071

This paper presents a new method for matching omnidirectional stereo images. The main idea of the proposed method consists in exploiting the temporal information for matching the stereo images acquired at the current time by involving the stereo images acquired at the preceding time. Three pairs are considered in the matching process, i.e., the current, the left temporally adjacent and the right temporally adjacent omnidirectional stereo images. All the three stereo pairs are used together in order to overcome the problem of blind spots near the epipoles. The proposed approach is achieved in three main steps. The first step performs the spherical rectification on the three input pairs. In the second step, we apply the proposed dynamic programming-based stereo matching algorithm on the resulting three rectified pairs. Disparity ranges for each scanline are computed from the v-disparity maps generated based on the disparity maps computed at the preceding time. This reduces the matching candidates and speeds up the matching process. In the final step, we combine the three disparity maps into a single 360° disparity map. The proposed method has been tested on real omnidirectional images and the results provided are promising.
提出了一种新的全向立体图像匹配方法。该方法的主要思想在于利用时间信息,通过涉及前一时刻获得的立体图像来匹配当前时刻获得的立体图像。在匹配过程中考虑三对,即当前、左时间相邻和右时间相邻的全向立体图像。为了克服磁极附近的盲点问题,所有三种立体对都被一起使用。提出的方法主要分三个步骤实现。第一步对三个输入对进行球面整流。在第二步,我们将提出的基于动态规划的立体匹配算法应用于得到的三个校正对。每条扫描线的视差范围是从基于之前计算的视差图生成的v-视差图中计算出来的。这减少了匹配候选,加快了匹配过程。在最后一步,我们将三个视差图合并成一个360°视差图。该方法已在真实的全向图像上进行了测试,结果令人满意。

This in these recent years, the interoperability of e-Government applications has been an extremely important research and development ICT domain to facilitate the seamless exchange of information across public and private sectors department of government. Many researchers and practitioners have focused on the adaptation and design of Government Interoperability Frameworks to do a form of relationship in the E-Government implementations. The major elements relevant to E-Government interoperability are conformance and compliance and there are a large number of Government applications that are available on the web. It is very difficult to automate interoperability because of the heterogeneity in the development of these. E-Government applications, the heterogeneous platforms on which the applications run, the complexity of web interface that is not machine-friendly and the Non-standard format used for data input/output. In this paper web services and business process engines have been developed as a standard based on the models of XML specification for message exchanged between heterogeneous applications by using a web services choreography language to remedy these problems.
近年来,电子政府应用程序的互用性已成为资讯及通讯科技研究及发展的一个极为重要的范畴,以促进公营及私营政府部门之间的资讯无缝交换。许多研究者和实践者关注于政府互操作性框架的调整和设计,以在电子政务实施中实现一种形式的关系。与电子政府互用性有关的主要因素是一致性和遵从性,而网上有大量的政府应用程序。由于开发过程中的异构性,实现互操作性的自动化是非常困难的。电子政府应用程序、应用程序运行的异构平台、对机器不友好的网络界面的复杂性以及用于数据输入/输出的非标准格式。在本文中,web服务和业务流程引擎已被开发为一种基于XML规范模型的标准,通过使用web服务编排语言来解决这些问题,以便在异构应用程序之间交换消息。

In this paper, we present a color texture characterization by studying novel information of complex wavelet coefficients which we call extended relative phase (ERP) information. By definition, this latter permits to consider relation between color subbands by using straightforward univariate models, and thus avoiding cumbersomeness of multivariate fitting. The ERP information is modeled by three well known circular distributions namely, VonMises (VM), Wrapped Cauchy (WC) and Vonn. All the three models present, advantages of simple feature extraction (using maximum likelihood estimation) and similarity measurement (known forms of Kullback-leibler divergence) steps, which extremely helps for the runtime issue. Experimental results on the Vistex database show that considering ERP inter color subbands improves retrieval performances over the use of conventional relative phase intra grayscale subbands.
本文通过研究复小波系数的新信息,即扩展相对相位(ERP)信息,提出了一种彩色纹理表征方法。根据定义,后者允许使用简单的单变量模型来考虑颜色子带之间的关系,从而避免了多变量拟合的繁琐。ERP信息由三个众所周知的循环分布建模,即VonMises (VM), Wrapped Cauchy (WC)和Vonn。这三种模型都具有简单的特征提取(使用最大似然估计)和相似度测量(已知形式的Kullback-leibler散度)步骤的优点,这对解决运行时问题非常有帮助。在Vistex数据库上的实验结果表明,考虑ERP色间子带比使用传统的相对相位灰度子带能提高检索性能。
