Novel DCT based feature extraction for enhanced Iris Recognition 基于DCT的虹膜特征提取方法
Abhiram M H Student, Chetan Sadhu, K. Manikantan, S. Ramachandran
Iris recognition (IR) under varying live-tissues is challenging, and extracting tissue edge features is an effective approach to solve this problem. In this paper, we propose a unique combination of edge detection plus DCT based feature extraction for enhanced Iris Recognition. Two novel methods, namely circular sector and triangular shaped DCT feature extraction techniques are proposed. Individual stages of the IR system are examined and an attempt is made to improve each stage. A Binary Particle Swarm Optimization (BPSO)-based feature selection algorithm is used to search the feature vector space for obtaining the optimal feature subset. Experimental results show the promising performance of circular sector DCT extraction for iris recognition on Phoenix, MMU, IITD databases.
不同活组织下的虹膜识别具有挑战性,而组织边缘特征提取是解决这一问题的有效方法。在本文中,我们提出了一种独特的结合边缘检测和基于DCT的特征提取来增强虹膜识别。提出了两种新的DCT特征提取方法,即圆形扇形和三角形特征提取技术。研究了红外系统的各个阶段,并尝试对每个阶段进行改进。采用基于二进制粒子群优化(BPSO)的特征选择算法对特征向量空间进行搜索,得到最优特征子集。实验结果表明,在Phoenix, MMU, IITD数据库上,圆形扇形DCT提取用于虹膜识别具有良好的性能。

Study and design of target tracking and antimissile launching by amplitude comparison monopulse radar tracking using MATLAB 利用MATLAB研究和设计了基于幅度比较单脉冲雷达跟踪的目标跟踪和反导发射
U. Patel, R. Petkar, D. Sharma, S. Vazirani
The purpose of air defense guided missile systems is to reduce or minimize the attacks by detecting and destroying enemy aircraft or missiles approaching a important area. These systems must be capable of defending strategic areas against attack from high altitude, high speed enemy aircraft by performing precision bombing on the aircraft and on the missiles launched by the aircraft. So to destroy the targets, the system must be capable of predicting the trajectory of the targets before and after the missile launch. Our study aims to study the amplitude monopulse radar system and designing a missile launching system which is able to calculate the predicted trajectory of the target based on the amplitude monopulse radar system using MATLAB. This missile launching system also calculates the trajectory of the missile used for destroying the target. The speed, azimuth and elevation angle for launching the missile is also calculated. This missile launching system is designed for stationary and moving objects having uniform speed or acceleration.
防空导弹系统的目的是通过探测和摧毁接近重要区域的敌机或导弹来减少或最小化攻击。这些系统必须能够通过对飞机和飞机发射的导弹进行精确轰炸,保卫战略区域免受高空、高速敌机的攻击。因此,为了摧毁目标,系统必须能够在导弹发射前后预测目标的轨迹。本课题旨在对幅值单脉冲雷达系统进行研究,利用MATLAB设计一种基于幅值单脉冲雷达系统的导弹发射系统,能够计算出目标的预测轨迹。该导弹发射系统还计算用于摧毁目标的导弹的弹道。同时计算了导弹发射的速度、方位角和仰角。这种导弹发射系统是为具有匀速或加速度的静止和运动物体设计的。

Sector coded transmission protocol for Cognitive Radio Networks 认知无线网络扇区编码传输协议
V. Abrol, P. Sharma
In practical Cognitive Radio Networks for Mobile Communication cluster based topology is used to increase spectrum detection performance. The energy of Head Node depletes faster than the member nodes and thus rotation of cluster head is needed for the energy efficiency of Cognitive Radio Networks. The level of hierarchy is increased in this approach by introducing a Super Node which communicates between the Head Nodes and the BTS. In this paper, a new scheme called Sector Coded Transmission (SCT) is proposed in which the Head Nodes are rotating with a two level hierarchy.
在实际的移动通信认知无线网络中,采用基于簇的拓扑结构来提高频谱检测性能。由于头节点的能量消耗比成员节点快,因此需要旋转簇头来提高认知无线网络的能量效率。在这种方法中,通过引入一个超级节点(Super Node)来增加层次结构的级别,该节点在头节点和BTS之间进行通信。本文提出了一种新的扇区编码传输(SCT)方案,该方案中头节点以两级层次结构旋转。

R. Ansari, M. Devanalamath, K. Manikantan, S. Ramachandran
This paper proposes a Digital Watermarking Algorithm using a unique combination of Discrete Wavelet Transform (DWT), Discrete Fourier Transform (DFT) and Singular Value Decomposition (SVD) for secured transmission of data through watermarking digital color images. The singular values obtained from SVD of DWT+DFT transformed watermark is embedded onto the singular values obtained from SVD of DWT+DFT transformed color image. Experimental results show the promising performance of the proposed algorithm for watermarking. Peak Signal to Noise Ratio (PSNR) values for the watermarked image in the range of 65 to 85 dB and maximum correlation of 0.9998 are achieved.

Prediction of DoS attack sequences DoS攻击序列预测
A. Reshamwala, S. Mahajan
A denial of service attack (DOS) is any type of attack on a networking structure to disable a server from servicing its clients. Attacks range from sending millions of requests to a server in an attempt to slow it down, flooding a server with large packets of invalid data, to sending requests with an invalid or spoofed IP address. Sequential pattern mining is an important data mining problem with broad applications. Sequential Pattern Mining is to discover the frequent sequential pattern in the sequential event dataset. Intrusion detection using sequential pattern mining is a research focusing on the field of information security. In this paper, we have implemented Apriori a candidate generation algorithm and PrefixSpan a pattern growth algorithm on a network intrusion dataset from KDD Cup 1999, 10 percent of training dataset, which is the annual Data Mining and Knowledge Discovery competition organized by ACM Special Interest Group on Knowledge Discovery and Data Mining, the leading professional organization of data miners. To address the absence of timestamp in the dataset, we considered two approaches to generate the sequence database from the dataset. One is by taking service as reference attribute and the other one by taking a timestamp window of size one day (86400 seconds). We found that experimental results of PrefixSpan for predicting DoS attacks sequences on KDD cup 99 training dataset are efficient. These results are then compared with SPAM (Sequential Pattern Mining) algorithm which uses vertical bitmap data layout allowing for simple, efficient counting.
拒绝服务攻击(DOS)是针对网络结构的任何类型的攻击,目的是使服务器无法为其客户端提供服务。攻击的范围包括向服务器发送数百万个请求以试图降低其速度,向服务器发送大量无效数据包,以及使用无效或欺骗的IP地址发送请求。顺序模式挖掘是一个重要的数据挖掘问题,有着广泛的应用。序列模式挖掘是在序列事件数据集中发现频繁的序列模式。基于顺序模式挖掘的入侵检测是信息安全领域的研究热点。在本文中,我们实现了Apriori候选生成算法和PrefixSpan模式增长算法,该算法来自1999年KDD杯的网络入侵数据集,该数据集占训练数据集的10%,该数据集是由ACM知识发现和数据挖掘特别兴趣小组组织的年度数据挖掘和知识发现竞赛,这是数据挖掘者的主要专业组织。为了解决数据集中缺少时间戳的问题,我们考虑了两种从数据集中生成序列数据库的方法。一种方法是将service作为引用属性,另一种方法是采用一天(86400秒)大小的时间戳窗口。实验结果表明,PrefixSpan在KDD cup 99训练数据集上预测DoS攻击序列是有效的。然后将这些结果与SPAM(顺序模式挖掘)算法进行比较,该算法使用垂直位图数据布局,允许简单,高效的计数。

This paper presents a new approach for the implementation of Karaoke Machine for vocal or instrument removal with recording user's voice and playback. Through the medium of this paper we are glad to showcase our observations and results. Karaoke is a form of entertainment in which users sing along with recorded music using a microphone. So first phase of our Karaoke machine involves removing the original voice of the artist in a song using Out of Phase Stereo method, then, we can record the user's voice while simultaneously playing the remaining music. In this paper, we present a real-time implementation of a Matlab/Simulink model of Karaoke Machine.
