Nowadays, a great amount of information is circulated through the Internet. Some of them exclusively belongs to a special group of users and requires protection and safeguarding against unauthorized access. To this end, a category of systems called HIP (human interactive proof) have been introduced to distinguish between various groups of users.
The reliable extraction of characteristic gait features from image sequences is an important issue in gait recognition. In this paper we propose a simple, but efficient approach to extract gait feature. In view of the spatio-temporal motion characteristic of gait, we adopt the shape variation information between successive frames to denote gait information, called interframe variation vector- IVV...
In this article, a novel logic which concerns with the natural property of context is presented, the cognitive state of the agent is considered and the dependency relationships between the word and the sentence, the word and the article, etc. can be inferred. First the cognitive dependency operator is put forward, then the logical system is established, the axioms and the properties of the system...
The more knowledge the expert system possesses, the more competent the system becomes. However the possibility of the occurrence of knowledge conflicts will become greater, and the efficiency of inference will become lower at the same time, which restricts capacity of the knowledge system. The problem oriented analysis and decision expert system(POADES) refers to the human thinking processes and methods,...
In this paper, an approach of image/video's automatic annotation considering semantics' tolerance relation between pre-defined classes is described. The image/videos' semantics is represented by a vector of associative values with the pre-defined classes. Moreover, the semantic gap induced in the process of automatically generating associative values is dealt with by using the constructed semantic...
The recent development of Web 2.0 has provided for an enormous increase in human interactions across all corners of the earth. One manifestation of this is the growth of computer mediated social networks. Many notable Web 2.0 applications such as Facebook, Myspace and LinkedIn are social networks. Social relational networks are becoming an important technology in human behavioral modeling. Our goal...
