Hashim Masod Kahily, A. Sudheer
This paper presents a prototype of a military robot which implements an application of real time detection and tracking of human beings. A depth sensing camera system by Microsoft Kinect is utilized on a physical robot for human detection and aiming in both static and dynamic modes of operation. Human detection in the static mode is obtained by using APIs of Open Natural Interaction (OpenNI) framework and the aiming routine is carried out using Regression Analysis between image pixels and the gun control motors. In the dynamic mode, human detection is done by implementing several algorithms such as voxelization of point clouds, RANSAC, and Histogram of Oriented Gradients in Point Cloud Library and the aiming routine is carried out using inverse kinematics.

Sushant Agrawal, Vikash Kumar, N. Anand, V. Agarwal, A. Islam
This paper proposes the design, analysis and processing methodologies for the data generated by the custom designed data logger for quick deployment. The primary goal is to develop a prototype system for automobiles which can reduce the `Acquisition to Analysis' time for the generated data. The proposed data acquisition (DAQ) system is rugged and modular. Since most existing DAQ systems fail for automotive use due to their application-specific nature and lack of data filtering and processing capabilities. The system so developed, log data at a baud rate of 9600 bps and employ 10-bit resolution for the representation of analog data from the sensor. This coupled with data logging using SD card shield V3.0 and data analysis on MATLAB graphical user interface helps to reduce the testing and prototyping time of vehicle under test.

Data hiding technique in video using a secrete key 使用密钥的视频数据隐藏技术
C. Raut
The interest in data hiding has increased with the recent activity in digital copyright protection. One way to protect the image is to secretely embed data in the content of the image. The content owner hide the original message using hiding key in any cover medium. The receiver does these processes in reverse for getting back the original message the data hiding key is employed to extract the secret message and get back the original content. In this paper we will present the overview on the use of data hiding technique using the improved LSB on video. One of the major disadvantage with simple LSB method is that, while inserting the secrete data into the target image it can change the least significant bit of all the image pixel. In this way hidden message will be destroyed by changing the quality of image. In order to overcome that limitations we are proposing improved LSB with 1,4,3 bit position technique is currently being developed. We are using the block size 4×4 to hide data. This paper will review development in data hiding technique, specifically it is secure data hiding in the image.
随着近年来数字版权保护的兴起,人们对数据隐藏的兴趣日益浓厚。保护图像的一种方法是在图像的内容中秘密地嵌入数据。内容所有者使用隐藏键在任何覆盖介质中隐藏原始消息。接收方反向执行这些过程以获取原始消息,使用数据隐藏密钥提取秘密消息并获取原始内容。在本文中,我们将概述使用改进的LSB在视频中使用数据隐藏技术。简单LSB方法的一个主要缺点是,在将秘密数据插入目标图像时,会改变所有图像像素的最低有效位。这种方法通过改变图像的质量来破坏隐藏信息。为了克服这些限制,我们提出了改进的LSB,目前正在开发1,4,3位位置技术。我们使用块大小4×4来隐藏数据。本文综述了数据隐藏技术的研究进展,特别是图像中的安全数据隐藏技术。

Design of automatic power consumption control system using smart grid — A review 基于智能电网的自动用电控制系统设计综述
P. Sakthivel, S. Ganeshkumaran
In smart grid, advanced metering infrastructure (AMI) is an important task for predicting the power consumption such that the balance of supply and demand in power market can be achieved. For designing a good communication infrastructure for the smart meters, it is necessary to study the short term power consumption pattern which is equivalent to the information source pattern in communication systems. To design a system to reduce the power consumption for individual users in scheduled duration Instead of power cuts there will be a scheduled restricted power supply. We implement GSM based remote controlling station from where we send control information consist maximum power consumption and restriction period. If the consumers uses more power than the allowed power, after a warning the system will shut down the power supply automatically.
在智能电网中,先进的计量基础设施是实现电力市场供需平衡的一项重要任务。为了设计一个良好的智能电表通信基础设施,有必要研究通信系统中相当于信息源模式的短期功耗模式。设计一个系统,以减少个人用户的电力消耗在预定的时间,而不是停电,将有一个计划的限制供电。我们实现了基于GSM的远程控制站,从远程控制站发送控制信息包括最大功耗和限制时间。如果用户使用的功率超过了允许的功率,系统将在警告后自动关闭电源。

Tushar M. Chaure, Kavita R. Singh
Frequent Itemset Mining is one of the most popular techniques to extract knowledge from data. However, these mining methods become more problematic when they are applied to Big Data. Fortunately, recent improvements in the field of parallel programming provide many tools to tackle this problem. However, these tools come with their own technical challenges such as balanced data distribution and inter-communication costs. In this paper, we are presenting a detailed survey of Hadoop, which helps in storing data and parallel processing in distributed environment. Here we have explored various Frequent Itemset Mining techniques on parallel and distributed environment. The aim of this paper is to present a comparison of different frequent itemset mining techniques and help to develop efficient and scalable frequent itemset mining techniques.

Anuja Lawankar, Nikhil Mangrulkar
Now a days Internet is widely used by users to satisfy their information needs. In the exponential growth of web, searching for useful information has become more difficult. Web crawler helps to extract the relevant and irrelevant links from the web. To optimizing this irrelevant links various algorithms and technique are used. Discovering information by using web crawler have certain issues; such as different URLs having the similar text which increase the time complexity of the search, crawler resources are wasted in fetching duplicate pages and larger storage is also required to store these web pages. These are some of the roadblocks in getting optimum results from the crawler. This paper provides a deep study of existing information retrieval techniques (I.R) which would help researchers to retrieve optimum result links and information.
现在,互联网被用户广泛使用,以满足他们的信息需求。在网络的指数级增长中,搜索有用的信息变得越来越困难。网络爬虫有助于从网络中提取相关和不相关的链接。为了优化这些不相关的链接,使用了各种算法和技术。利用网络爬虫发现信息存在一定的问题;例如,不同的url具有相似的文本,这增加了搜索的时间复杂度,爬虫资源浪费在获取重复的页面上,并且还需要更大的存储空间来存储这些网页。这些都是从爬虫中获得最佳结果的一些障碍。本文对现有的信息检索技术进行了深入的研究,以帮助研究人员检索最优的结果链接和信息。

J. Nithya, P. Latha
Wireless network is a type of computer networks where communication or data exchange among various devices on the network are carried out without the use of cables. Connecting clients is through a wireless network having a wireless Access Point (AP) instead of an Ethernet switch. Recent advancements in Wireless Energy Transfer (WET) technologies are enabling various engineering applications with potential implementation. RF-enabled WET provide a solution called Wireless Powered Communication (WPC). WPC technique is used to power the wireless devices by transmitter to offer uninterrupted, constant energy. WET technology can be utilized to charge the batteries in the equipment without the need for a wired connection. In WET technology, receivers harvest power distantly from RF signals. The receiver change the received energy to Direct Current signal and stores into battery. In SWIPT technology, both energy and information equally transmits to the multiple receivers by using Hybrid Access Point(HAP). HAP include a energy trade off method together in source, destination designs to equilibrium the Information Decoding and Energy Collecting presentation. In WPCN technology, all wireless devices transmits the information and communicates with each other by using the harvested energy. It operates beneath a two process collect then transmit protocol.
无线网络是一种计算机网络,在网络上的各种设备之间进行通信或数据交换而不使用电缆。通过具有无线接入点(AP)而不是以太网交换机的无线网络连接客户端。无线能量传输(WET)技术的最新进展使各种工程应用具有实现的潜力。支持rf的WET提供了一种称为无线供电通信(WPC)的解决方案。WPC技术通过发射机为无线设备供电,以提供不间断的、恒定的能量。WET技术可以用来给设备中的电池充电,而不需要有线连接。在WET技术中,接收器从远离射频信号的地方获取能量。接收器将接收到的能量转换为直流电信号并存储到电池中。在SWIPT技术中,能量和信息通过混合接入点(HAP)均匀地传输到多个接收器。在源端、目标端设计中采用能量权衡方法,平衡了信息解码和能量收集的表现。在WPCN技术中,所有的无线设备都利用收集到的能量来传输信息并相互通信。它在一个双进程收集然后传输协议下运行。

Automatic segmentation of fruits in CIELuv color space image using hill climbing optimization and fuzzy C-Means clustering 基于爬坡优化和模糊c均值聚类的CIELuv彩色空间图像水果自动分割
P. Ganesan, B. Sathish, G. Sajiv
In this paper, a novel method for the segmentation and extraction of natural fruits using Hill climbing (HC) optimization and Modified Fuzzy C-Means (MFCM) clustering algorithm is proposed. The intensity and color information is highly correlated in RGB color images. The segmentation in RGB color space does not produce the meaningful outcome for the segmentation and information retrieval. Many authors have proposed different color space for the segmentation and retrieval of information. In this color based segmentation technique, RGB color images had transformed into perceptually uniform, device independent CIELuv color space for the efficient segmentation. Then for the CIELuv image, the color histogram had generated and computed. This color histogram acts as a search space and has a number of bins. In this work, Hill climbing (HC) optimization had applied for the identification of best image pixels (peaks) which correspond to the initial number of seeds or clusters for the segmentation process. These initial seeds had applied to MFCM for the segmentation of fruits in CIELuv color images. The experimental result had compared with the segmentation process in RGB color space to demonstrate the efficiency of the proposed approach.
本文提出了一种基于Hill climb (HC)优化和改进模糊c均值(MFCM)聚类算法的天然水果分割与提取新方法。在RGB彩色图像中,强度和颜色信息高度相关。在RGB颜色空间中进行分割不能产生有意义的分割结果和信息检索。许多作者提出了不同的颜色空间来分割和检索信息。在这种基于颜色的分割技术中,RGB彩色图像被转换成感知上一致的、与设备无关的CIELuv颜色空间,从而实现了高效的分割。然后对CIELuv图像进行颜色直方图的生成和计算。这个颜色直方图作为一个搜索空间,有许多箱子。在这项工作中,爬山(HC)优化应用于识别最佳图像像素(峰值),这些像素(峰值)对应于分割过程中种子或聚类的初始数量。将这些初始种子应用于MFCM,用于CIELuv彩色图像中果实的分割。实验结果与RGB颜色空间的分割过程进行了比较,验证了该方法的有效性。

Occlusion invariant face recognition system 遮挡不变人脸识别系统
Ashwini S. Khadatkar, R. Khedgaonkar, K. S. Patnaik
Face recognition has acquired a lot of attention in market and research communities, but still remained very accosting in real time applications. It is one of the several techniques used for identifying an individual. In face recognition system there are many factors which affect the performance of a system. The major factors affecting the face recognition system are pose, illumination, ageing, occlusion and expression etc. Among the above mentioned problem an occlusion is most affecting problem in face recognition. In a face recognition system due to obstacles like sunglasses, scarf etc. we cannot recognize a face image. So first we detect an occlusion from a face image by using a SVM (Support Vector Machine) classifier. To resolve the occlusion problem, each face is divided into k local regions which are analyzed in isolation. We discard an occluded part in a face image and based on remaining non-occluded part of a face image we will recognize a face image. For face recognition purpose we will be using a near set theory.
人脸识别在市场和研究领域受到了广泛的关注,但在实时应用中仍然存在很大的问题。这是用来识别个体的几种技术之一。在人脸识别系统中,影响系统性能的因素很多。影响人脸识别系统的主要因素有姿势、光照、年龄、遮挡和表情等。在上述问题中,遮挡是影响人脸识别的最大问题。在人脸识别系统中,由于太阳镜、围巾等障碍物,我们无法识别人脸图像。因此,我们首先使用支持向量机分类器从人脸图像中检测遮挡。为了解决遮挡问题,将每个人脸划分为k个局部区域,并对其进行隔离分析。我们丢弃人脸图像中被遮挡的部分,并基于人脸图像中剩余的未遮挡部分来识别人脸图像。为了人脸识别的目的,我们将使用近集理论。

In this paper, a tri band compact octagonal fractal monopole MIMO antenna is presented. The proposed antenna is microstrip line fed and its structure is based on fractal geometry where the resonance frequency of antenna is lowered by applying iteration techniques. The simulated bandwidth of the antenna are 2.3706GHz to 2.45GHz, 3.398GHz to 3.677GHz and 4.9352GHz to 5.8988GHz (S11 <; -10 dB), covering the bands of WLAN and WiMAX. The characteristics of small size, nearly omnidirectional radiation pattern and moderate gain make the proposed MIMO antenna entirely applicable to WLAN and WiMAX applications. The proposed antenna has compact size of 50 mm × 50 mm. Details of the proposed antenna design and performance are presented and discussed.
