J. Glagolevs, Kārlis Freivalds
In this paper we present a study of logo detection in images from a media agency. We compare two most widely used methods — HOG and SIFT on a challenging dataset of images arising from a printed press and news portals. Despite common opinion that SIFT method is superior, our results show that HOG method performs significantly better on our dataset. We augment the HOG method with image resizing and rotation to improve its performance even more. We found out that by using such approach it is possible to obtain good results with increased recall and reasonably decreased precision.
在本文中,我们提出了从一个媒体机构的图像标志检测的研究。我们比较了两种最广泛使用的方法- HOG和SIFT对来自印刷媒体和新闻门户网站的具有挑战性的图像数据集。尽管人们普遍认为SIFT方法更好,但我们的结果表明HOG方法在我们的数据集上表现得更好。我们通过图像大小调整和旋转来增强HOG方法,以进一步提高其性能。我们发现,通过使用这种方法,可以在提高召回率和合理降低精度的情况下获得良好的结果。

G. Staigvila, V. Novickij
Electroporation by Pulsed ElectroMagnetic Field (PEMF) is a novel, non-invasive technique, which has high potential and applicability in biomedicine and biotechnology. In this work, we present a concept of a high dB/dt and high power system (kA, kV range) for further application in PEMF electroporation experiments. The concept includes an array of synchronized SCRs (silicon controlled rectifiers) driving a high power ignitron. A pulsed power inductor is used as a load. The parameters of the system are selected based on the experimental results with a Marx generator circuit, which was used as a proof of concept. Finite element method (FEM) simulation of the expected spatial distribution of pulsed magnetic field is also presented in the study.

Experimental investigation of feature descriptors for retinal image registration 视网膜图像配准特征描述符的实验研究
E. Šabanovič, D. Matuzevičius
Retinal imaging is an important test for diagnosis of eye diseases and treatment evaluation. One of the steps in eye fundus image processing is image registration. It is inevitable in order to eliminate geometrical differences, introduced during imaging with different settings or pursuing follow up disease screenings. One of available strategies for image alignment is feature-based approach where feature descriptors have an important role in registration process. The quality of feature descriptors affects feature matching performance and overall results of image registration. In this paper we present a comparison of various feature extractors in tandem with conventional, bio-inspired or deep neural network-based local feature detectors applied for retinal image registration. Comparative evaluation of descriptors has been carried out using Fundus Image Registration Dataset, measuring Euclidean distance between ground truth points after image alignment. We present the results showing the performance of various feature detector-descriptor pairs applied for retinal image registration.
视网膜成像是眼科疾病诊断和治疗评价的重要检测手段。眼底图像处理的一个重要步骤是图像配准。为了消除几何差异是不可避免的,这些差异是在不同设置的成像过程中引入的,或者是在进行后续疾病筛查时引入的。基于特征的图像对齐方法是一种有效的图像对齐策略,其中特征描述符在配准过程中起着重要的作用。特征描述符的质量影响着特征匹配的性能和图像配准的整体效果。在本文中,我们比较了各种特征提取器与传统的、生物启发的或基于深度神经网络的局部特征检测器在视网膜图像配准中的应用。使用眼底图像配准数据集对描述符进行比较评价,测量图像对齐后地面真值点之间的欧氏距离。我们展示了用于视网膜图像配准的各种特征检测器-描述符对的性能。

Extension of hardware-accelerated real-time task schedulers for support of quad-core processors 硬件加速实时任务调度器的扩展,支持四核处理器
L. Kohútka, V. Stopjaková
This paper presents the design of a coprocessor that performs an efficient task scheduling for quad-core real-time systems. The proposed solution is based on two algorithms: Earliest Deadline First (EDF) algorithm that is proved to always find an optimum ordering of hard real-time tasks and the priority-based FCFS algorithm, which is suitable for non-real-time tasks. The proposed coprocessor can efficiently handle any combination of both types of tasks even though they use different parameters for scheduling. Thanks to HW implementation of the scheduler, the operations are performed in two clock cycles regardless of the current and the maximum number of tasks in the system. The proposed coprocessor is optimized for quad-core CPUs, which can lead to much higher performance of real-time embedded systems than the other schedulers. An existing approach originally designed for dual-core systems was used, known as semaphore approach. The new scheduler was verified using UVM and 256 million instructions with randomly generated deadline/priority values. The synthesis results of the new coprocessor designed for quad-core CPUs were compared to the synthesis results of previous versions of the scheduler. The quad-core version of the scheduler consumes only from 1% to 27% more LUTs than the single-core version.
本文设计了一种用于四核实时系统的高效任务调度的协处理器。该解决方案基于两种算法:最早截止日期优先(EDF)算法和基于优先级的FCFS算法,前者被证明总能找到硬实时任务的最优排序,后者适用于非实时任务。所提出的协处理器可以有效地处理这两种任务的任何组合,即使它们使用不同的调度参数。由于调度器的HW实现,操作在两个时钟周期内执行,而不管系统中的当前和最大任务数是多少。所提出的协处理器针对四核cpu进行了优化,这可以使实时嵌入式系统的性能比其他调度器高得多。使用了最初为双核系统设计的现有方法,称为信号量方法。新的调度器使用UVM和2.56亿条带有随机生成的截止日期/优先级值的指令进行了验证。将新设计的四核cpu协处理器的综合结果与以前版本的调度程序的综合结果进行了比较。四核版本的调度器只比单核版本多消耗1%到27%的lut。

Comparison of TDC parameters in 65 nm and 0.13 μm CMOS 65 nm和0.13 μm CMOS中TDC参数的比较
Marijan Jurgo, R. Navickas
In this paper parameters of time to digital converter (TDC), which is often used as phase detector in all-digital frequency synthesizers, designed in 65 nm and 0.13 μm CMOS integrated circuit technologies, were analyzed. The structure of the designed TDC is a variety of 2D Vernier time to digital converter, based on gated ring oscillators. Performance of these oscillators has biggest impact on resolution of TDC. Therefore, oscillators were simulated using analog approach using Cadence integrated circuit design software. Simulations were carried out in nominal (1.2 V, 40 °C, typical transistor models), worst (1.1 V, 40 °C, slow transistor models) and best (1.3 V, −40 °C, fast transistor models) operation conditions. In the nominal operation conditions, the frequency of gated ring oscillator can be tuned from 0.68 GHz to 3.38 GHz and from 0.33 GHz to 0.71 GHz respectively in 65 nm and 0.13 μm technology. The delay of single stage can be changed from 491 ps to 98 ps and from 1.013 ns to 0.466 ns respectively in 65 nm and 0.13 μm CMOS. At least 3 and 5 sections of oscillator need to be enabled respectively in 65 nm and 0.13 μm CMOS for oscillator to start. Tuning step of oscillator's stage delay, which corresponds to resolution of TDC, in nominal operating conditions can be changed from 3.4 ps to 0.8 ps and from 5.8 ps to 1.1 ps respectively in 65 nm and 0.13 μm CMOS, when number of enabled oscillator's sections is changed from 20 to 48. Total area of silicon occupied by TDC is 123 μm × 148.8 μm in 65 nm CMOS technology and 244.2 μm × 295.8 μm in 0.13 μm CMOS technology.
本文分析了采用65 nm和0.13 μm CMOS集成电路设计的全数字频率合成器中常用的鉴相器TDC (time - to -digital converter)的参数。所设计的TDC的结构是基于门控环振荡器的各种二维游标时间到数字转换器。这些振荡器的性能对TDC的分辨率影响最大。因此,利用Cadence集成电路设计软件采用模拟方法对振荡器进行仿真。在标称(1.2 V, 40°C,典型晶体管模型)、最差(1.1 V, 40°C,慢速晶体管模型)和最佳(1.3 V, - 40°C,快速晶体管模型)运行条件下进行了仿真。在标称工作条件下,在65 nm和0.13 μm工艺下,门控环振荡器的频率分别可在0.68 GHz至3.38 GHz和0.33 GHz至0.71 GHz范围内调谐。在65 nm和0.13 μm CMOS中,单级延迟分别从491 ps和1.013 ns变化到98 ps和0.466 ns。在65 nm和0.13 μm CMOS中,至少需要使能3段和5段振荡器才能启动。在65 nm和0.13 μm CMOS中,当使能振荡器的节数从20个增加到48个时,在标称工作条件下,对应于TDC分辨率的振荡器级延迟的调谐步长可以分别从3.4 ps增加到0.8 ps和5.8 ps增加到1.1 ps。在65 nm CMOS工艺中,TDC占用的硅总面积为123 μm × 148.8 μm;在0.13 μm CMOS工艺中,TDC占用的硅总面积为244.2 μm × 295.8 μm。

Julius Skirelis, D. Navakauskas
Edge computing, the subsidiary model of Cloud computing, is aiming to push computational resources closer to the edge of network. Its objectives are to improve network latency and ensure efficiency of performed tasks. However Internet of Things (IoT) devices usually are of limited processing power or/and connecting to network episodically, mostly due to power saving necessity and mobility. Thus in the paper investigation of the performance of edge computing for IoT is presented. Multiple simulations by EdgeNetworkCloudSim of different topologies, their parameters, together with considered IoT device primary limitations, are carried out. Simulation results confirm the specificity of edge computations for IoT and gives some practical insights.
边缘计算是云计算的附属模型,旨在推动计算资源更接近网络边缘。其目标是改善网络延迟并确保执行任务的效率。然而,物联网(IoT)设备通常具有有限的处理能力或/或间歇性地连接到网络,主要是由于节能需求和移动性。因此,本文对物联网边缘计算的性能进行了研究。EdgeNetworkCloudSim对不同拓扑及其参数进行了多次模拟,并考虑了物联网设备的主要限制。仿真结果证实了物联网边缘计算的特殊性,并给出了一些实用的见解。

A. Poreva, Y. Karplyuk, V. Vaityshyn
The article considers the basic methods of machine learning for applying them to the task of the lungs sounds classifying. A number of signal parameters were obtained on the basis of the lungs sounds set. The task of the study was to classify sounds using five different machine learning methods. It was also necessary to determine from a number of signal parameters those that give the highest accuracy. Thus the seven most diagnostically valuable parameters of lung sounds were found. The results showed that two methods of machine learning — the method of reference vectors and the decision tree method — have the best accuracy. Thus this classification technique can serve as an auxiliary tool for a pulmonary physician to diagnosis.

Thus this classification technique can serve as an auxiliary tool for a pulmonary physician to diagnosis.","PeriodicalId":224275,"journal":{"name":"2017 5th IEEE Workshop on Advances in Information, Electronic and Electrical Engineering (AIEEE)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125596786","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Embedded software performance estimations at different compiler optimisation levels 不同编译器优化水平下的嵌入式软件性能评估
P. Ruberg, Keijo Lass, Elvar Liiv, P. Ellervee
Tools for performance estimation based on instruction set simulators (ISS) are mostly available and show good results. However when the need arises to choose a different platform or to estimate performance without having the ISS the developer needs all the different software suits and devices and also must be able to work with them. In this case we propose an estimation method based on physical measurement for generating performance models. This paper extends our previous work on source-code level performance estimations for microcontrollers. We compare two proposed estimation methods to find the most suitable for estimating embedded software performance for C source-code level on microcontrollers with higher compiler optimisation levels than −O0. As a result we show that both methods could be applied with some exceptions.
基于指令集模拟器(ISS)的性能评估工具大多可用,并显示出良好的效果。然而,当需要在没有ISS的情况下选择不同的平台或评估性能时,开发人员需要所有不同的软件套件和设备,并且还必须能够使用它们。在这种情况下,我们提出了一种基于物理测量的估计方法来生成性能模型。本文扩展了我们以前在微控制器源代码级性能估计方面的工作。我们比较了两种提出的估计方法,以找到最适合在编译器优化水平高于- 0的微控制器上估计C源代码级嵌入式软件性能的方法。结果表明,除了一些例外,这两种方法都可以应用。
