Interpreting background is very important in natural scene images. This paper addresses the automaticclassification of background region by using visual semantic template. The method to create the templates is intro-duced first. Then we use these templates to classify background regions, and the results are analyzed. We also usethese templates to locate background objects in images, and to determine whether an image contains certain kind ofbackground. The result is promising in object locating. Some approaches to improve the ability of these templates arealso discussed.

A novel and fast shape classification and regularization algorithm for on-line sketchy graphics recognition is proposed. We divide the on-line graphics recognition process into four stages: preprocessing,shape classification,shape fitting,and regularization. Attraction Force Model is employed to progressively combine the vertices on the input sketchy stroke and reduce the total number of vertices before the type of shape can be determined. After that ,the shape is fitted and gradually rectified to a regular one,thus the regularized shape fits the user intended one *** results show that this algorithm can yield good recognition precision(averagely above 90% )and fine regularization effect but with fast speed. Consequently,it is especially suitable to computational critical environment such as PDAs,which solely depends on a pen-based user interface.

Some usual one-time password authentication protocols are analyzed. A practical efficient one-time pass-
word authentication implementing method is presented based on the symmetric algorithm, which conquers usual chal-
lenge-response protocol weakness and can protect user's identity and avoid replay attack etc. It also can boost up the
security of the application security system by integrating with it in networks. And the correlative issues are discussed
deeply such as security, reliability and so on.

Agent technology provides a flexible and uniform framework for Web and distributed applications,and interoperability is one of the most critical problems for agent technology to become mature and practical. This article analyzes the interoperability problem of Agent deeply. It first discusses the main research work about agent interoperability,namely OMG's MAF specification and the set of specifications of FIPA,and points out their drawbacks. Then a research model covering the main aspects of interoperability in Agent environment is brought up,and a reference model for agent system is also provided,which fully corresponds with the research model for agent *** two models have nice universality and adaptability,and provide a practical reference for building an Agent system with good interoperability.
