Rosalina, Lita Yusnita, N. Hadisukmana, R. B. Wahyu, Rusdianto Roestam, Yuyu Wahyu
Sign language is a language that requires the combination of hand gesture, orientation, movement of the hands, arms, body, and facial to simultaneously express the thoughts of the speaker. This paper implements static hand gesture recognition in recognizing the alphabetical sign from “A” to “Z”, number from “0” to “9”, and additional punctuation mark such as “Period”, “Question Mark”, and “Space”in Sistem Isyarat Bahasa Indonesia (SIBI). Hand gestures are obtained by evaluating the contour representation from image segmentation of the glove wore by user and then is classified using Artificial Neural Network based on the training model previously built from 100 images for each gesture. The accuracy rate of hand gesture translation is calculated to be 90%. Speech translation recognized NATO phonetic letter as the speech input for translation.
手语是一种需要结合手势、方位、手、手臂、身体和面部的运动来同时表达说话者思想的语言。本文实现了静态手势识别,用于识别印尼语中字母符号“A”到“Z”、数字“0”到“9”以及附加标点符号“句号”、“问号”和“空格”。通过对用户佩戴的手套图像分割后的轮廓表示进行评估得到手势,然后利用基于100张图像的训练模型的人工神经网络对每个手势进行分类。计算出手势翻译的准确率为90%。语音翻译识别北约语音字母作为语音输入进行翻译。

Fat separation using grid fit method at high-field MRI 网格拟合方法在高场MRI中的脂肪分离
S. Eun, E. Jung, Dong-Kyun Park, T. Whangbo
In high-field magnetic resonance imaging (MRI), water-fat separation in the presence of B0 field inhomogeneity is important research. Various field map estimation techniques that use three-point multi-echo acquisitions have been developed for reliable water fat separation. Among the numerous techniques, iterative decomposition of water and fat with echo asymmetry and least squares estimation (IDEAL) has gained considerable popularity as an iterative method for acquiring high-quality water and fat images. However, due to the worsened B0 in homogeneity at high-field, IDEAL cannot adjust for meaningful field map estimation, particularly for a large field of view. Previously, to improve the robustness of this estimation, a region-growing (RG) technique was developed to take advantage of the 2D linear extrapolation procedure through the seed point set by the median value in the target object. There are some limitations with this approach, such as the dependence on the initial seed point, such as a number, intensity, and position of the seed point. In this work, we introduce a effective method called the improved Grid-fit method that does not need to consider parameters related with accuracy. As a result of the proposed method, we obtained a effective fat quantification result that can be applied in high-fields, with an average water residual rate of 7.2% higher than the existing method.
在高场磁共振成像(MRI)中,B0场不均匀存在下的水脂分离是一个重要的研究课题。为了实现可靠的水脂分离,已经开发了各种使用三点多回波采集的野外图估计技术。在众多的技术中,基于回声不对称和最小二乘估计的水脂肪迭代分解(IDEAL)作为一种获取高质量水脂肪图像的迭代方法得到了广泛的应用。然而,由于高视场均匀性B0的恶化,IDEAL无法进行有意义的视场图估计,特别是对于大视场。在此之前,为了提高该估计的鲁棒性,开发了一种区域增长(RG)技术,通过目标对象中值设置的种子点来利用二维线性外推过程。这种方法有一些局限性,例如依赖于初始种子点,例如种子点的数量、强度和位置。本文介绍了一种不需要考虑与精度相关参数的改进网格拟合方法。结果表明,该方法可有效应用于高油田,平均残水率比现有方法提高7.2%。

Hierarchical graph neuron scheme in classifying intrusion attack 入侵攻击分类的层次图神经元算法
Aulia Essra, O. S. Sitompul, Benny Benyamin Nasution, R. Rahmat
Hierarchical Graph Neuron (HGN) is an extension of network-centric algorithm called Graph Neuron (GN), which is used to perform parallel distributed pattern recognition. In this research, HGN scheme is used to classify intrusion attacks in computer networks. Patterns of intrusion attacks are preprocessed in three steps: selecting attributes using information gain attribute evaluation, discretizing the selected attributes using entropy-based discretization supervised method, and selecting the training data using K-Means clustering algorithm. After the preprocessing stage, the HGN scheme is then deployed to classify intrusion attack using the KDD Cup 99 dataset. The results of the classification are measured in terms of accuracy rate, detection rate, false positive rate and true negative rate. The test result shows that the HGN scheme is promising and stable in classifying the intrusion attack patterns with accuracy rate reaches 96.27%, detection rate reaches 99.20%, true negative rate below 15.73%, and false positive rate as low as 0.80%.

Adaptive spatiotemporal similarity measure for a consistent depth maps 一致深度图的自适应时空相似性度量
Yong-Ho Shin, Kuk-jin Yoon
When computing a depth map sequence of a stereo image sequence, the temporal consistency of computed depth maps is a very important factor along with the accuracy. In this paper, we propose a new similarity measure for spatiotemporal stereo matching aiming at producing temporally consistent depth maps from a stereo image sequence. To enforce the temporal consistency in a spatiotemporal similarity measure, we assign adaptive support weights to pixels in a spatiotemporal window and define the four-dimensional support region in consideration of the motion and depth variation along the time. In addition, we model the support weight to be less sensitive to illumination variation. The similarity is computed simply by comparing two support regions with computed support weights. The proposed similarity measure truly improves the performance of stereo matching both in the accuracy and in the consistency aspects.
在计算立体图像序列的深度图序列时,计算深度图的时间一致性和精度是一个非常重要的因素。在本文中,我们提出了一种新的时空立体匹配相似度度量,旨在从立体图像序列中生成时间一致的深度图。为了增强时空相似性度量中的时间一致性,我们在时空窗口中为像素分配自适应支持权,并根据运动和深度随时间的变化定义四维支持区域。此外,我们还建立了对光照变化不太敏感的支撑权重模型。通过比较两个支持区域与计算的支持权重,简单地计算相似度。所提出的相似度度量确实提高了立体匹配的精度和一致性。

Adaptive video coding selection scheme for solar-powered wireless video sensor networks 太阳能无线视频传感器网络的自适应视频编码选择方案
Jun Yi, Ikjune Yoon, D. Noh
Recently, the use of wireless sensor networks to collect video data for environmental observation or monitoring has been increasing, but they are not suitable for transmitting large video data due to the limitation of node energy. Energy-harvesting node could be used to overcome this limitation, but the harvested energy is also limited. Therefore, an efficient energy utilization method is required to transmit a large amount of video data. This paper proposes a scheme to reduce the number of blackout nodes and increase the amount of collected data by selecting an appropriate video encoding method according to energy condition of the node in a solar-powered wireless sensor network. To collect data continuously regardless of day or night, this scheme allocates the amount of energy that can be used by time, and selects a coding with a high-compression ratio if the allocated amount is large, or a coding with a low-compression ratio if it is small. In this way, the blackouts of relay nodes are reduced and data can be transmitted continuously, which increases the amount of data arriving at the sink node. The simulation results verified confirmed that the proposed scheme prevented the energy exhaustion of the relay nodes and collected more data compared to using one coding only.
近年来,利用无线传感器网络采集环境观测或监测视频数据的应用越来越多,但由于节点能量的限制,不适合传输大型视频数据。能量收集节点可以用来克服这一限制,但收集的能量也是有限的。因此,需要一种高效的能量利用方法来传输大量的视频数据。本文提出了在太阳能无线传感器网络中,根据节点的能量状况选择合适的视频编码方法,减少停电节点数量,增加采集数据量的方案。为了不分昼夜地连续采集数据,该方案将可使用的能量按时间进行分配,如果分配的能量大,则选择高压缩比的编码,如果分配的能量小,则选择低压缩比的编码。这样减少了中继节点的停电,可以连续传输数据,增加了到达汇聚节点的数据量。仿真结果验证了该方案避免了中继节点的能量耗尽,与只使用一种编码相比收集了更多的数据。

Malware behavior analysis using binary code tracking 恶意软件行为分析使用二进制代码跟踪
Jihun Kim, Jonghee M. Youn
The rapidly increasing malware goes beyond personal security threats and has a negative effect on criminal society. To prevent these security threats, many anti-virus vendors and analysts are starving to more efficiently distinguish malicious behavior. In order to contribute to this, in this study, we try to detect malicious behavior by tracking the execution flow of binary code. Our method of tracking the execution flow of the binary code utilizing the BFS(Breath-First Search)algorithm advances static analysis based on binary code, but it can be a method combining the advantage of static analysis and the advantage of dynamic analysis. In addition to visualizing malicious behavior as a graph image based on APIs, it is possible to analyze more obviously malicious behavior.
迅速增加的恶意软件已经超越了个人安全威胁,并对犯罪社会产生了负面影响。为了防止这些安全威胁,许多反病毒供应商和分析人员都渴望更有效地区分恶意行为。为此,在本研究中,我们尝试通过跟踪二进制代码的执行流程来检测恶意行为。我们利用BFS(Breath-First Search)算法跟踪二进制代码执行流程的方法是基于二进制代码的静态分析,但它可以是一种结合静态分析和动态分析优点的方法。除了将恶意行为可视化为基于api的图形图像之外,还可以分析更明显的恶意行为。
