The bulk synchronous parallelism (BSP) model is useful in developing scalable software for parallel computation. To adapt the BSP model to the grid environment, the BSP-G, a BSP development library based on the services of Globus Toolkit has been proposed. In this paper, we further the work of BSP-G and introduce an agent assisted ServiceBSP model. The(More)
Web services technology has provided a mechanism that greatly enhances the interoperability between service users, either human or machine. However there is an existing gap between the dynamic selection of services and the automatic integration of applications, partially due to the lack of semantics in the current Web services standards. To narrow this,(More)
A novel distinctive descriptor named MSOGH is proposed, which is able to well represent the interest region and is robust to photometric transformations and geometric transformations. According to intensity order, subregions are firstly constructed. Then feature descriptor of the subregion is computed by point permutation of the sample points in each(More)
