Efficient Video Authentication for H.264/AVC

Efficient Video Authentication for H.264/AVC

引用

International Conference on Innovative Computing, Information and Control (ICICIC)

作者： Jing Zhang A.T.S. Ho School of Electrical and Electronic Engineer Nanyang Technological University Singapore School of Electronics and Physicsal Sciences University of Surrey Guildford Surrey UK

This paper proposed a novel and efficient scheme to authenticate the H.264/AVC video. The scheme makes an accurate usage of the tree-structured motion compensation, motion estimation and Lagrangian optimization of the standard. Authentication information is embedded strictly based on the best mode decision strategy in the sense that if undergone any spatial and temporal attacks, the scheme can detect the tampering by the sensitive mode change. And the experimental results prove the effectiveness the algorithm against many transcoding and signal processing attacks

A PSO-based Mobile Sensor Network for Odor Source Localization in Dynamic Environment: Theory, Simulation and Measurement

Congress on Evolutionary Computation

作者： W. Jatmiko K. Sekiyama T. Fukuda Department of Micro-Nano Systems Engineering University of Nagoya Japan

This paper presents a problem of odor source localization in a dynamic environment, which means the odor distribution is changing over time. Most work on chemical sensing with mobile robots assume an experimental setup that minimizes the influence of turbulent transport by either minimizing the source-to-sensor distance in trail following or by assuming a strong unidirectional air stream in the environment, including our previous work. However, not much attention has been paid to the natural environment problem. Modification Particle Swarm Optimization is a well-known algorithm, which can continuously track a changing optimum over time. PSO can be improved or adapted by incorporating the change detection and responding mechanisms for solving dynamic problems. Charged PSO, which is another extension of the PSO, has also been applied to solve dynamic problems. Odor source localization is an interesting application in dynamic problems. We will adopt two types of PSO modification concepts to develop a new algorithm in order to control autonomous vehicles. Before applying the algorithm for real implementation, some important hardware conditions must be considered. Firstly, to reduce the possibility of robots leaving the search space, a limit to the value of velocity vector is needed. The value of vector velocity can be clamped to the range [-V max , V max ]; in our case for the MK-01 Robot, the maximum velocity is 0.05 m/s. Secondly, in the standard PSO algorithm there is no collision avoidance mechanism. To avoid the collision among robot we add some collision avoidance functions. Finally, we also add some sensor noise, delay and threshold value to model the sensor response. Then we develop odor localization algorithm, and simulations to show that the new approach can solve such dynamic environment problems.

Optimization of a Sun-Sensor Illumination Pattern using Genetic algorithms

Optimization of a Sun-Sensor Illumination Pattern using Gene...

引用

Canadian Conference on Electrical and Computer Engineering (CCECE)

作者： Godard John Enright Department of AeroSpace Engineering Ryerson University Toronto ONT Canada

changes to the illumination pattern in a digital sun-sensor can dramatically improve the resolution of the device. In this study we use genetic algorithms (GAs) as a heuristic to optimize the illumination pattern for a single-axis digital sun-sensor. The main objective is to determine an illumination pattern that resolves the sun-angle to better than one pixel. A linear-phase super resolution technique is proposed, to evaluate the effective resolution of the illumination pattern determined using GA. Our finding show that patterns with multiple, narrow peaks provide sub-pixel accuracy in resolving the sun-angle. Performance of the proposed GA estimator displayed the evolution of high-fitness solutions. We contend that multiple peak patterns can greatly improve the performance of the sun-sensor when coupled with parametric methods of displacement estimation. The optimal illumination pattern can be implemented by fabricating a replacement aperture mask for the sensor - a change that can be made at minimal cost

Source detection Using Repetitive Structure

Source Detection Using Repetitive Structure

引用

International Conference on Acoustics, Speech, and Signal Processing (ICASSP)

作者： R.M. Parry I. Essa College of Computing / GVU Center Georgia Institute of Technology Atlanta GA USA

Blind source separation algorithms typically require that the number of sources are known in advance. However, it is often the case that the number of sources change over time and that the total number is not known. Existing source separation techniques require source number estimation methods to determine how many sources are active within the mixture signals. These methods typically operate on the covariance matrix of mixture recordings and require fewer active sources than mixtures. When sources do not overlap in the time-frequency domain, more sources than mixtures may be detected and then separated. However, separating more sources than mixtures when sources overlap in time and frequency poses a particularly difficult problem. This paper addresses the issue of source detection when more sources than sensors overlap in time and frequency. We show that repetitive structure in the form of time-time correlation matrices can reveal when each source is active

SICE Annual Conference

作者： Gu-young Jeong Kee-ho Yu Division of Mechatronics Engineering Chonbuk National University of Korea Jeonju South Korea Division of Mechanical and AeroSpace System Engineering Chonbuk National University of Korea Jeonju South Korea

In this paper, we describe the hardware configuration for the ambulatory ECG monitoring device and the algorithm for detection of ST pattern change. The ambulatory ECG recording are available for diagnosis of the heart diseases such as myocardial infarction, arrhythmia, etc. It especially is important to detect the transient ECG pattern change caused by the unbalance between the oxygen supply and the oxygen demand in the cardiac muscle that is called myocardial ischemia. This is one of the reasons why the ambulatory ECG monitoring system is necessary. We designed the portable ECG measurement device with the analysis algorithm. The algorithm analyzes the ECG signal and detects the transient ST changes. The detection of QRS complex is accomplished using its the morphological characteristics such as the steep slope and high amplitude. The developed algorithm detects the ST level change, and then classify the ST shape type using the polynomial approximation. The algorithm finds the least squares curve for the data between S wave and T wave in ECG. This curve is used for the classification of the ST shapes. ST type is classified by calculating the difference between the reference ST type and the least square curve. Through the result from the developed algorithm, we can know when the ST level change occurs and what the ST shape type is. The portable ECG device consists of instrumentation amplifier, multiplexer, micro-controller, filter and transmitter module. The designed ECG device measures ECG with four electrodes on the body and transmits the measured ECG signal to the receiver connected in PC by digital radio way. The available range of wireless communication is 70 m in building and 300 m in open ground

Simulations illustrate that the new approach can solve such dynamic problems in advection-diffusion odor model environment

作者： Chun-Chyuan Chen Chien-Chin Chen Jiun-Ming Wu Department of Electrical Engineering National Dong Hwa University Hualien Taiwan

A robust multi-path searcher for the 3GPP WCDMA system is proposed in this paper. In the proposed multi-path searcher, a fast searcher quickly estimates the multi-path delays. A sounding system and a novel path-selection algorithm enhance the reliability of the output path delays. According to the simulation results, the multi-path searcher can detect the signal power fast even if the multi-path delays abruptly change. Additionally, the architecture of the robust multi-path searcher has low-complexity for hardware design.

detection and Segmentation of Moving Objects in Video

Detection and Segmentation of Moving Objects in Video

引用

Canadian Conference on Electrical and Computer Engineering (CCECE)

作者： Kunio Takaya Department of Electrical Engineering University of Saskatchewan Saskatoon SAS Canada

This paper proposes to define moving objects in video scene in terms of MPEG like motion vectors. Local areas in a video scene where large magnitude of motion vectors is detected are regarded to contain a moving object(s). Macro blocks indicating a large motion vector are segmented from the frame of video image. In order to identify the moving object with information relevant to its geometric shape, and to track the moving object, the segmented parts of video image are further processed to find salient corners with the SUSAN edge/corner detector. Local minima of the output from the SUSAN algorithm are the representative feature points of the moving object. For the motion tracking applicable to video surveillance, correspondence between the frame to frame change of those feature points is calculated by the Scott and Longuet-Higgins algorithm, which provides a direct way of associating features of two arbitrary patterns consisting of feature points

International Conference on Collaborative Computing: Networking, Applications and Worksharing (CollaborateCom)

作者： Felix Hupfeld Minor Gordon Zuse Institute Berlin Berlin Germany University of Cambridge Cambridge UK

Optimistic replication allows mobile workspaces to remain accessible during interrupted network access, but require consecutive handling of any conflicts. When conflict handling requires manual intervention by the user, the system must not require that conflicts are resolved immediatley after their detection. We present a log-based algorithm for reconciling changes to replicated data that supports deferred manual conflict resolution, while sharing the favorable scalability properties of log-based approaches of small storage and communication overhead. Simulation results validate our design and show that it compares favorably in the relevant metrics with version vector-based designs.
