| Summary: | 碩士 === 崑山科技大學 === 資訊管理研究所 === 94 === This goal of this paper is to present an e-learning platform designed and built with image and indication based on semi-3D. The platform functions to display and search anatomical structures. A modified K-Mean algorithm is used to speed up the object cutting process that will accelerate the background removing procedure of teach material authoring. A minimum bounding rectangle structure is implemented by using the general relational database in order to break the limitation of database server selection. The crossing test algorithm is used to implement the mark retrieval functions. Teaching images are divided into multi-resolutions and multi-block sub-images to be displayed for teaching purpose. It reduces the network transmission time when images are panned, zoomed in or zoomed out. A set of human anatomical images is used to demonstrate the ability of this platform. The proposed system is constructed by marks authoring, marks searching, teaching material presentation, audio guiding and evaluation modules, so this system is suitable for other courses that put emphasis on the morphological demonstration and 3D distribution of structures.
