The Research Of Content-Based Image Retrieval Based On Grid

With the development of multimedia and Internet technology, the application of the image is more and more extensive. How to retrieve necessary information from large amount image information efficiently and quickly needs to be solved urgently. The Content-Based Image Retrieval (CBIR) has become one of the hot research areas in image domain for large image database. In the past several ten years, many researchers proposed various different CBIR algorithms to enhance the speed and accuracy of image retrieval, but that still can not meet the actual needs of people. The emergence of grid for the solution to this problem provides a new way.As a new distributed technology, the grid technology has been mature. It provides an efficient managing way of distributed resource, strong computational power, excellent system expansibility, breaks the limit of computational power, storage, resource distributing, the way of sharing resource. It should be a fire-new experiment combining grid and CBIR technology. As a result, this paper researches on the architecture of CBIR based on grid, and proposes a solution of CBIR based on grid, namely, above the grid layer, a new layer of CBIR is build as a universal CBIR platform.This paper first introduces the technology of CBIR and grid. Secondly, the paper puts forward a new scheme by combination of CBIR and grid in order to solve the resent problems of CBIR. Next, the paper designs a CBIR system based on grid and particularly expatiates on the framework of CBIR system and the design of each module of CBIR system. It provides a resolving method and idea with great prospect for CBIR. This Paper successfully installs, configuring and tests GT4 under the Windows operation system, establishes a simple virtual organization as a simulative Grid environment and procedures for the preparation of image retrieval in the simulative Grid environment to develop Grid services for testing related functions. Finally, this paper summarizes the writer's research work, looks forward to the developing directions and sets the base of succeeding work.
