Rashmi Vashisth, Akshit Sharma, S. Malhotra, Saurabh Deswal, Aman Budhraja
In this paper, we are introducing a robot with a gesture controlled 3-axis accelerometer (ADXL335) with an ATmega16 microcontroller. Gesture recognition is a topic which comes under the purview of the computer science, Electronics & Communication and language technologies field for the purpose of interpreting human gestures with the help of mathematical algorithms. The gestures can be interpreted from any kind of physical movement or condition, but usually arise from a person. Gesture recognition can be explained as a method by which a computer can understand the language of the human body, thereby creating a communication bridge between humans and machines than normal text based or a terminal user interfaces or even graphical user interfaces (GUIs) that still restrict most of the mouse and keyboard inputs.
在本文中,我们介绍了一种带有ATmega16微控制器的手势控制3轴加速度计(ADXL335)的机器人。手势识别是一个属于计算机科学、电子与通信和语言技术领域的主题,目的是借助数学算法来解释人类的手势。这些手势可以从任何一种身体运动或情况来解释,但通常是由人产生的。手势识别可以解释为计算机能够理解人体语言的一种方法,从而在人与机器之间建立了一个沟通的桥梁,而不是普通的基于文本或终端用户界面甚至图形用户界面(gui),这些界面仍然限制了大多数鼠标和键盘输入。

FPGA implementation of unsigned multiplier circuit based on quaternary signed digit number system 基于四进有符号数制的无符号乘法器电路的FPGA实现
Radhika Thakur, Shruti Jain, M. Sood
Digital systems are mainly used in data processing, control systems and computation. They are having numberof advantages over analog system: one of advantage is fast arithmetic operation. There are different techniques for performing arithmetic operations such as Binary Signed Digit(BSD), Wallace, Booth multiplication etc. Using binary number system for arithmetic operation generates carry which creates delay and reduce the speed of operation. To overcome this problem we are using higher radix number system such as Quaternary Signed Digit (QSD). QSD number system is base 4 number system. QSD is represented by decimal numbers as : 0, 1, 2 and 3. It is responsible for carry free arithmetic operations. In this paper we proposed a high speed, low power QSD multiplier which is capable of doing carry free operation. This circuit can multiply both signed and unsigned numbers without any extra delay. This circuit also increases the speed of operation and is less complex. The circuit is simulated on XilinxSPARTAN 3E-100or250 field programmable gate array (FPGA) board using Verilog HDL.
数字系统主要用于数据处理、控制系统和计算。与模拟系统相比,它们具有许多优点:其中一个优点是快速的算术运算。执行算术运算有不同的技术,如二进制符号数(BSD)、华莱士、布斯乘法等。采用二进制进行算术运算会产生进位,造成运算延迟,降低运算速度。为了克服这个问题,我们使用了更高的基数系统,如四元有符号数(QSD)。QSD数制是4进制数制。QSD用十进制数字表示为:0、1、2和3。它负责无进位算术运算。本文提出了一种高速、低功耗、可进行免进位运算的QSD乘法器。这个电路可以将有符号数和无符号数相乘,而不会有任何额外的延迟。这种电路也提高了操作速度,而且不那么复杂。该电路在XilinxSPARTAN 3e - 100或250现场可编程门阵列(FPGA)板上使用Verilog HDL进行仿真。

Polynomial based fractal image compression using DWT screening 基于小波变换筛选的多项式分形图像压缩
P. Chauhan, Bhumika Gupta, Upendra Ballabh
Picture pressure is a fundamental innovation in sight and sound and advanced correspondence fields. Fractal picture pressure is a potential picture pressure plot because of its potential high pressure proportion, quick decompression and multi determination properties. Fractal picture pressure uses the presence of self symmetry of pictures. It is an lopsided method which take more time in compression than decompressing an image. The intellection is to do utmost of the work during compression. However the high computational unpredictability of fractal picture encoding incredibly limits its applications. A few procedures and enhancements have been recommended to accelerate the fractal picture pressure on polynomial insertion. This paper introduces an audit of the methods such as DWT and CLAHE distributed for speedier fractal picture compression using polynomial introduction with pre pack. Preliminary results shows a quite improvement in compression ratio, mean square blunder and the pinnacle flag to clamor proportion (PSNR).
图像压力是视觉、声音和高级通信领域的一项根本性创新。分形图压力具有潜在压力比例高、解压缩快、可多次测定等特点,是一种潜在的图压力图。分形图像压力利用图像的自对称存在。它是一种不平衡的方法,在压缩时比在解压缩时花费更多的时间。我们的想法是在压缩过程中尽最大努力工作。然而,分形图像编码的高计算不可预测性极大地限制了它的应用。本文介绍了几种加速多项式插入分形图像压力的方法和改进方法。本文介绍了采用多项式引入和预压缩的方法来提高分形图像压缩速度的DWT和CLAHE分布方法。初步结果表明,压缩比、均方误差和尖峰旗噪比(PSNR)均有较大改善。

A survey on cost aware task allocation algorithm for cloud environment 云环境下成本感知任务分配算法研究
Manish Gupta, Anurag Jain
Cloud computing is a reliable computing platform for large computational intensive or data intensive tasks. This has been accepted by many industrial giants of software industry for their software solutions, companies like Microsoft, Accenture, Ericson etc has adopted cloud computing as their first choice for cheap and reliable computing. But which increase in number of clients adopting this there is requirement of much more cost efficient and high performance computing for more trust and reliability among the client and the service provide to guarantee cheap and more efficient solutions. So the tasks in cloud need to be allocated in an efficient manner to provide high resource utilization and least execution time for high performance, at the same time provide least computational cost as cloud follows pay-per use model. Many resource algorithms are been proposed to improve the performance, but are not cost efficient at same time. Algorithms like genetic, particle swarm and ant colony algorithm are efficient solutions but not cost efficient. So this paper presets an study of various existing algorithms.
云计算是大型计算密集型或数据密集型任务的可靠计算平台。这已经被许多软件业的工业巨头所接受,他们的软件解决方案,像微软,埃森哲,爱立信等公司已经采用云计算作为他们廉价可靠的计算的首选。但是,随着采用这种方法的客户端数量的增加,需要更高的成本效益和高性能计算,以提高客户端和服务提供之间的信任和可靠性,以保证廉价和更有效的解决方案。因此,需要以有效的方式分配云中的任务,以提供高资源利用率和最少的执行时间来实现高性能,同时提供最少的计算成本,因为云遵循按使用付费模型。为了提高性能,人们提出了许多资源算法,但这些算法的成本效率都不高。遗传算法、粒子群算法和蚁群算法是有效的解决方案,但成本效益不高。因此,本文首先对现有的各种算法进行了研究。

Area and power efficient register allocation technique for the implementation of PCA 实现PCA的面积和功耗高效寄存器分配技术
Sukhmani K. Thethi, Ravi Kumar
This paper presents a novel register allocation technique as well as the conventional technique for the implementation of Principal Component Analysis (PCA) incorporating variable reuse technique. PCA deals with a large dimensional data and is a computationally intensive technique. The purpose of this paper is to avoid register switching and hence reduction in dynamic power consumption as well as area during the implementation of PCA. Syntheses of verilog codes written for both the techniques were carried out in RC (cadence) tool. In case of generic synthesis, a substantial decrease of 56.867% in power and 56.66% in case of area was observed; whereas, in case of mapped synthesis, significant reduction of 86.145% in power and 74.79% in area was observed for the proposed technique in contrast to the conventional one.

Identifying big data dimensions and structure 确定大数据的维度和结构
Meenu Dave, Jahangir Kamal
As the Big Data gets recognition, everything that is being stored electronically in bulk cannot be termed as Big Data. Nowadays efforts are being made to extract maximum useful information from analyzing Big Data, as it contains growing value to the organization and actionable relationships are abundantly found in Big Data stores as compared to the small stores. Big Data from various organizations or industries is being recognized on the basis of certain characteristics (dimensions) and structure. The characteristics of Big Data started with 3Vs (Volume, Velocity, and Variety), but new dimensions are getting evolved day by day and thus broadening the dimensions and definition of Big Data. In this paper, the growing characteristics and structure of Big Data with new definitions from academia and corporate world have been elaborated.
随着大数据得到认可,所有以电子方式大量存储的东西都不能被称为大数据。如今,人们正在努力从分析大数据中提取最大限度的有用信息,因为大数据对组织的价值越来越大,与小数据商店相比,大数据商店中有大量可操作的关系。来自各个组织或行业的大数据是基于一定的特征(维度)和结构被认可的。大数据的特征从3v (Volume, Velocity, Variety)开始,但新的维度也在不断进化,从而拓宽了大数据的维度和定义。本文阐述了学术界和企业界对大数据的新定义以及大数据日益增长的特点和结构。

Combinational feature approach: Performance improvement for image processing based leaf disease classification 组合特征方法:基于图像处理的叶片病害分类性能改进
M. Goswami, S. Maheshwari, Amarjeet Poonia
Plant disease is main reason of agricultural crops production losses. Leaf disease in plant occurs due to fungai, virus and bacterias. Image contains various important features which is used in classification. In this paper author initially detect disease then classify disease using extracted features. It takes five diseased leaves (Black rot, Black Measles, Leaf blight, Septoria leaf spot, Bacterial spot) and healthy leaf images then identify leaf is diseased or healthy then if leaf is diseased then classify type of disease. Color features mean, standard deviation, skewness and kurtosis computed then Region based shape feature calculated to identify the size of spots. Texture feature calculated using gray level co-occurrence matrix (GLCM) which identifies texture of image using distance and 45° angle variation in GLCM. Extracted features sent to trained feed forward neural network and classify diseased with color, shape and texture feature individually and combination of all features then observe that combination of color, shape and texture feature improve the performance of classification accuracy.

Extracted features sent to trained feed forward neural network and classify diseased with color, shape and texture feature individually and combination of all features then observe that combination of color, shape and texture feature improve the performance of classification accuracy.","PeriodicalId":142166,"journal":{"name":"2017 4th International Conference on Signal Processing, Computing and Control (ISPCC)","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122960557","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}
