This paper proposes a shot-based key frame selection technique, aiming at generating a condensed set of frames representing the essential content of a video sequence. Inspired by the successful utilization of Jensen-Shannon Divergence (JSD) and Jensen-Rényi Divergence (JRD) for key frame selection [1] [2], we investigate several popularly accepted f-divergences for calculating the frame-by-frame distance...
Driver behavior model is one of the key technologies for the driver assistance and safety system which can provide useful priori knowledge for detecting the abnormal behaviors effectively. The paper introduces the Driver behavior model which is established by the parallel Bayesian networks with steering angles and their difference and the final status of driver behavior is decided by the largest probability...
In order to meet the practical need of a number of scientific researchers during the task of simulation modeling and to overcome some shortcomings of the existing simulation modeling tools, this paper presents a new simulation platform KD-VisualSimIDE. It is emphasized on the whole structure of this platform, especially the design and implementation of the model editor which is an important part of...
Along with the rapidly advancement of the computer hardware and software technology, special-purpose simulation computer system has gradually failed to keep pace with the developing and application trend of simulation technology. So in its development process, simulation computer gradually got rid of the customization road, gradually choose a common path. KDRTS (Ke Da real time simulation system),...
Due to the features of interaction between malicious codes, the cooperation becomes more and more common. In this paper, cooperation between worm and virus is discussed in detail, and a cooperation model named CM model is proposed to describe the dynamical process of propagation. Results of simulation and mathematic analysis show that the propagation performance is significantly improved with the...
We proposed a worm detection and defense system named bot-honeynet in this paper, which combines the best features of honeynet, anomaly detection and botnet. The combination of honeynet and anomaly detection system offers a tradeoff between false positive and false negative rates. The control mechanism of botnet can help our system control all the honeypots in the bot-honeynet. Bot-honeynet is designed...
Satellite tool kit (abbr. STK) is a professional space-analysis software widely used in all phases of a space systempsilas life cycle. The simulation of STK is efficient and accurate relatively. Sometimes STK can not run efficiently. Maybe some other software can be used to make up. The problem of how to integrate applications with STK is faced during program exploring. An approach for integrating...
