international conference on signal Processing, Communication, Computing and Networking Technologies

With the explosion of networks and the huge amount of data transmitted along, securing data content is becoming more and more important. Data encryption is widely used to ensure security in open networks such as the internet. This paper presents the implementation of stream cipher, where the key stream is generated based on the properties of Linear Feedback Shift Register and cyclic Elliptic Curve over a finite prime field. In this paper we illustrate the process of encryption/decryption of an image in spatial domain and also encrypt key file parameters needed for generating the key stream to other parties using Elliptic Curve Cryptography. Therefore the encrypted key file parameters are only transmitted and not the entire full length key. Since Elliptic Curve Cryptography is replacing RSA for key exchange and Elliptic Curve based stream cipher offers a good choice for encryption in real time application. The strength of the proposed cipher lies in the generation of random sequence using Linear Feedback Shift Register over GF(p), difficulty of Elliptic Curve Discrete Logarithmic Problem and the entire key need not be transmitted in the encryption process. This paper also discusses the security aspects of the proposed cipher which is secure against all kinds of attacks.

international conference on Communication Software and Networks, ICCSN

作者： Yang Jie Chen Xuezhao Hunan University of science and Engineering Yongzhou China Yongzhou Vocational and Technical College Yongzhou China

MPEG-4 is one of the most important and influential international standard for multimedia data compression coding in the commercial world, its full name is generic coding of audio and visual objects. It defines the audio, video and other multimedia syntax and decoding process, the transmission on the internet and a whole set of framework about the interaction between human and media, which covering the vast majority of multimedia applications. Its object-based thought enables it a high compression ratio, good flexibility, scalability and interactivity, and other advantages. This paper combines the practical application background of mobile communications, and carries out a key research on the core part of MPEG-4 standard - video compression coding, on basis of a comprehensive understanding of MPEG-4 standard. Firstly, an in-depth study on the basic principles and algorithm of MPEG-4 digital video standard has been done.

Segmentation of skin cancer images based on gradient vector flow (GVF) snake

IEEE international conference on Mechatronics and Automation

作者： Khalad Abu Mahmoud Adel Al-Jumaily School of Electrical Mechanical and Mechatronic Systems University of Technology Sydney Sydney NSW AU School of Electrical Mechanical and Mechatronic Systems University of Technology Sydney NSW Australia

A gradient vector flow (GVF) snake is proposed in this paper for the segmentation of skin cancer images. In order to make the snake insensitive to noise and be able to remove the hairs, an Adaptive Filter (Wiener and Median filters) is proposed. After the noise and hairs are removed, GVF snake will be used to segment the skin cancer region. The GVF snake extends the single direction and allows it to still be able to track the boundary of the skin cancer even if there are other objects near the skin cancer region. We have proposed new operators to find better edge map in a restored grey scale image. Subjective method has been used by comparing the performance of the proposed gradient vector flow (GVF) snake with other recommended operators of first derivative like Sobel, Prewitt, Roberts and second derivative like Laplacian. The root mean square error and root mean square of signal to noise ratio have been used for objective evaluation. Finally, to validate the efficiency of the filtering schemes different algorithms are proposed and the simulation study has been carried out. Experiments performed on 8(eight) cancer images show the effectiveness of the proposed algorithm.

international conference on Intelligent systems Design and Applications (ISDA)

Recognizing handwritten mathematical content is a challenging problem, and more so when such content appears in classroom videos. However, given the fact that in such videos the handwritten text and the accompanying audio refer to the same content, a combination of a video and an audio based recognizer has the potential to significantly improve the content recognition accuracy. In this paper, using a combination of video and audio based recognizers, we focus on improving the character recognition accuracy in such videos and propose: (1) synchronization techniques for establishing a correspondence between the handwritten and the spoken content, and (2) combination techniques for combining the outputs of the video and audio based recognizers. The current implementation of the system makes use of a modified open source text recognizer and a commercially available phonetic word-spotter. For evaluation purposes, we use videos recorded in a classroom-like environment and our experiments demonstrate the significant improvements (≈ 24% relative increase as compared to the baseline video based recognizer) in character recognition accuracy that can be achieved using our techniques.

international conference on Awareness Science and technology (iCAST)

作者： Yan Zhuang Shengpeng Yang Xiaotao Li Wei Wang Research Center of Information and Control Dalian University of Technology Dalian China

ISBN: (纸本)9781457708879

In this paper, we describe a visual odometry algorithm based on a novel 3D range data registration approach for mobile robot. Considering traditional range image's limited adaptability in outdoor environment representation, a Bearing Angle model is used in this paper so that local SIFT (Scale-invariant feature transform) features can be extracted and matched effectively. According to the one-to-one correspondence between Bearing Angle image and raw 3D laser data, we can obtain a group of matching pairs between any two successive laser scans, which can be used to accomplish the 3D range data registration. Compared to the conventional ICP (Iterative Closest Point) algorithm, this approach can greatly improve the performance of scan registration both in computation time and accuracy. Furthermore, no initial rough pose estimation is needed in the registration. The frame-to-frame motion estimate can be performed by using the relative pose estimations resulting from the registration. Finally, experimental results are provided to demonstrate the effectiveness of the proposed visual odometry algorithm during the wheel odometry is unavailable or GPS (Global Positioning System) signal outages.

A passive universal image steganalysis method is proposed that is shown to be of higher detection accuracy than existing truly blind steganalysis methods including Farid's and the WAM. This is achieved by improving some weaknesses of Farid's steganalysis scheme in feature extraction, that is, instead of deriving an over-determined equation system for each sub band of the wavelet decomposition, the sub bands are divided into overlapping blocks and an over-determined equation system is constructed for each block. To guarantee the existence of finite answers, the over-determined equation systems are solved in a way different from Farid's by using Moore-Penrose pseudo-inverse concept. Further improvement to the performance is achieved by adding diagonal directions and increasing the number of moments. The comparative evaluations confirm the superiority of the proposed method over prevalent blind steganalysis schemes.
