Imbalance problem is widespread in machine learning. Most learning algorithms can’t get satisfied performance when they are applied on imbalance data sets, because they can be deteriorated by this problem easily. This paper proposed SDSMOTE method which captures the spatial distribution of imbalance data sets, and changes the tendency of learning algorithm by over sampling by oversampling according to the recognition difficulty. Experiments on 5 UCI data sets validate the effectiveness of this oversampling algorithm.

Computed Tomography (CT) has been used in many fields. Practical misalignment of the actual CT system causes geometric artifacts in the reconstructed images, which severely degrades image quality. Geometric artifact evaluation provides a reliable basis for subsequent geometric artifact correction. Some characteristics of images, such as entropy and sharpness, are often used to measure the severity of geometric artifacts, but they are limited in generality and accuracy. Convolutional neural network (CNN) has excellent image feature learning capabilities and is well used in image processing. This paper explores the network structure suitable for the evaluation of geometric artifacts in CT images. We select three commonly used networks LeNet-5, VGG16 and AlexNet. The datasets of three kinds of phantoms are constructed using simulation and actual scanning results. The three networks are trained and tested separately on the three kinds of datasets. Experimental results show that all three CNN models can evaluate the existence of geometric artifacts in CT images. The AlexNet network achieves the best classification evaluation performance with an average classification accuracy of 0.961, with the smallest average loss and the shortest training time.
计算机断层扫描(CT)在许多领域都有应用。实际CT系统的实际不对准会在重建图像中产生几何伪影,严重降低图像质量。几何伪影评价为后续的几何伪影校正提供了可靠的依据。图像的一些特征,如熵和锐度,通常用于测量几何伪像的严重程度,但它们在通用性和准确性方面受到限制。卷积神经网络(CNN)具有优异的图像特征学习能力,在图像处理中得到了很好的应用。本文探讨了一种适合于CT图像中几何伪影评价的网络结构。我们选择了三种常用的网络LeNet-5, VGG16和AlexNet。利用仿真结果和实际扫描结果构建了三种不同类型的图像数据集。三个网络分别在三种数据集上进行训练和测试。实验结果表明,这三种CNN模型都能评估CT图像中是否存在几何伪影。AlexNet网络的分类评价性能最好,平均分类准确率为0.961,平均损失最小,训练时间最短。

In a distributed video coding (DVC) system, side information(SI) is the estimated frame of the original Wyner-Ziv(WZ) frame, which has an important impact on the performance of the whole system. High quality SI is helpful for the decoder to restore Wyner-Ziv frames. For this reason, based on the analysis of the existing methods of generating SI, we propose a new SI generation method. Two categories of SI are generated by motion compensation frame interpolation(MCFI) and optical flow interpolation, and then they are fused based on a probability fusion method to obtain more accurate SI. The experiment results indicate that the Hybrid SI generation algorithm proposed in this work can effectively improve the quality of SI.

Generative Adversarial Network (GAN) is a kind of deep learning model and one of the most promising methods for unsupervised learning in complex distribution in recent years. Due to the need for higher hardware support, it has certain limitations in practical application. Therefore, how to use the fast-developing Web technology and Cloud technology to promote and share it is a difficult problem. To address this issue, the theme is based on the hot model of GAN, combined with the thinkPHP framework, using python and php language, then, by means of the Cloud computing technology and bootstrap technology, the interactive response system for image style transformation between the mobile terminal and the server terminal is subsequently realized, which conforms to the development trend and expansion characteristics of the mobile terminal. This scheme can be promoted to art creators or the general public to meet their needs for artistic inspiration or image style transformation and ultimately to achieve a complete chain of resource collection, information processing and service feedback.

Subspace-based methods are attractive solutions to localization problems due to their satisfactory performance and super-resolution property. In large-scale MIMO systems, the prohibitive computational complexity induced by direct eigenvalue decomposition of the high-dimensional covariance matrix severely limits their practical application. In this paper, a Nyström-based method is proposed to solve the complexity problem. A randomized SVD procedure embedded with orthogonal iteration is introduced into the proposed method which releases the computational burden to a big extent. To address the degradation problem of the proposed method in low SNR scenario, an approximate noiseless covariance matrix is devised based on Nyström approximation. Numerical experiments indicate that the proposed method can obtain adequate performance compared with the standard Nyström method as well as the classical subspace-based method, while the complexity of the proposed method is further reduced which makes it a more practical option in large-scale MIMO systems.
基于子空间的方法以其令人满意的性能和超分辨率特性成为求解定位问题的有效方法。在大规模MIMO系统中,高维协方差矩阵的直接特征值分解导致的计算复杂度严重限制了其实际应用。本文提出了一种Nyström-based方法来解决复杂性问题。该方法引入了嵌入正交迭代的随机奇异值分解过程,极大地减轻了计算量。为了解决该方法在低信噪比情况下的退化问题,设计了基于Nyström近似的近似无噪声协方差矩阵。数值实验表明,与标准的Nyström方法和经典的基于子空间的方法相比,该方法可以获得足够的性能,同时进一步降低了该方法的复杂度,使其在大规模MIMO系统中更加实用。

Speech content is often faced with malicious forgery and tampering in transit. Therefore, we introduce a novel fragile watermarking algorithm by modifying the least significant digits for speech content authentication and tampering recovery. In this letter, the proposed authentication scheme consists of two processes: the first one is watermark generation and embedding, the second one is content authentication and recovery. In the former process, the compressed speech signal, frame number and check information are generated based on speech content to form a watermark. Subsequently, the generated watermark is embedded into the least significant digits of speech sampling points using the proposed watermarking algorithm. In the latter process, the embedded watermark is utilized to locate the tampered area and recover that tampered content synchronously. Experimental results show that the proposed watermarking algorithm is fragile to common signal processing. Additionally, it has favorable inaudibility, accurate location ability and high recovery quality.

There are many methods of thread measurement. In addition, these thread measurement methods require manual segmentation of regions of interest (threaded area) and These methods are easily disturbed by the environment (e.g. dust, iron filings, oil stains, etc.), resulting in inaccurate measurement results. This paper proposes an external thread measurement method based on ResUnet and hidden Markov model (HMM). First, we propose a ResUnet-based thread edge recognition method that omits the process of calibrating the threaded area and identify the thread edge in a complex environment. Secondly, we use HMM to classify the thread edge points so that the threaded parts can be placed at any angle during the measurement, simplifying the measurement steps and calculating the thread parameters based on the classification results. Finally, we evaluated our method using our own dataset, and the results showed that the difference between the measured value and the standard value is within 0.01 mm.

Software Defined Networks paradigm decouples network control from switches and is directly programmable. A relatively centralized control plane together with developed APIs between control and data plane allows it to retrieve a global view of network traffic. Traffic estimation algorithm, which aims to generate a realtime and precise traffic flow undergoing with acceptable overhead, is fundamental for traffic engineering and QoS guarantee. A few traffic estimation algorithms is proposed based on Software Defined Networks paradigm, such as Flowsense and Payless. We propose a reactive traffic estimation algorithm to retrieve network traffic information. This reactive traffic estimation algorithm sends two query messages after a flow table is installed, and estimates upper bound bandwidth. We run a simulation on Mininet with Ryu as controller and OVS as data plane switch to test proposed algorithm. Simulation shows that this algorithm shows a better comprehensive performance in aspect of realtime and bandwidth overhead.
软件定义网络范例将网络控制从交换机中分离出来,并且是直接可编程的。相对集中的控制平面以及在控制平面和数据平面之间开发的api允许它检索网络流量的全局视图。流量估计算法是流量工程和QoS保证的基础,其目的是生成实时、精确且开销可接受的流量流。提出了几种基于软件定义网络范式的流量估计算法,如Flowsense和Payless。提出了一种响应式流量估计算法来检索网络流量信息。此响应式流量估计算法在安装流表后发送两条查询消息,并估计上限带宽。我们以Ryu为控制器,OVS为数据平面交换机,在Mininet上进行了仿真测试。仿真结果表明,该算法在实时性和带宽开销方面具有较好的综合性能。
