The robust tracking algorithm is presented that can automatically track the human including partial or total occlusion in the paper. Firstly, as a result of the use of Camshift, the effectiveness of particle is improved, and the tracking window can change scale with the target adaptively; Secondly, the multiple cues integration technique is brought into the… (More)
This paper presents a fast texture synthesis method for the terrain model based on recognition of the terrain features. In this method, two algorithms have been proposed. One is the extraction algorithm of terrain profile feature based on a hierarchical structure. The advantage is that the feature lines of terrain can be presented directly into a tree… (More)
This article discusses the problems in the emergency resource deployment, establishes a time-centered mathematical model. It uses the genetic algorithm to solve the problem in the resource allocation, makes a useful improvement, detailed analyses the elements of genetic algorithm in calculating the optimal deployment path, and demonstrates the influence of… (More)
The paper proposes a new concept similarity computing model. In this model, concept similarity computation is extended by properties constructor. Comparative experimental results show that the OCTF have achieved higher accuracy than that of T-L BACH and OCSim algorithms.
