Three-dimensional reconstruction of medical images can provide the direct, real sense for doctors and play an important role in clinical medicine. The medical images can be reconstructed by using the VTK (visualization toolkit). In this paper, we proposed a new method for medical image reconstruction platform which is developed based on ITK (Insight Segmentation and Registration Toolkit) and VTK....
How to provide cost effective, high performance spatial relation/spatial predicate implementation is one important issue for Internet map server design. To avoid the disadvantages of computational geometry algorithm approach, it proposes one improved method, combined with the rendering engine, which can enhance the filter accuracy. This proposal can record coverage area of border grid cells accurately...
How to provide cost effective, high performance spatial query and spatial analysis implementation is one important issue for internet map server design. In this paper, we present one novel, rasterization approach to internet map server design and implementation. Like most modern internet map server implementation, this system stores pre-rendered map image tiles for different scales on the web server,...
It is a critical technique in GIS about how to implement spatial relation/spatial predicate with high performance. To avoid the disadvantages of computational geometry algorithm approach, we propose one improved method, combined with the rendering engine, which can enhance the filter accuracy and avoid drawbacks of four color raster signature (4CRS). This proposal can record coverage area of border...
The spatial index method is one critical factor affecting the query performance in the case of web feature service. The R-tree method, which is one popular method used in spatial database, has limitations for web feature service. In this paper, we propose one rasterization spatial index method utilizing AGG as the engine for the mapping between geographic features and image pixels. After illustrating...
Small and medium sized enterprises (SMEs) in China feature their big quantity and fast developing speed. Itpsilas a huge requirement for them to establish e-commence business through their website portals. This paper proposes a template-based E-commence website Builder (TEB) for them, which is easy to use and flexible to extend. Each template in TEB is composed of multiple template pages with tags...
