The proposed method learns from the most informative objects which are marked by the user, and then creates a boundary separating the relevant models from irrelevant ones. What it needs is only a small number of 3D models labelled by the user. It can grasp the user＇s semantic knowledge rapidly and accurately. Experimental results showed that the proposed algorithm significantly improves the retrieval effectiveness. Compared with four state-of-the-art query refinement schemes for 3D model retrieval, it provides superior retrieval performance after no more than two rounds of relevance feedback.展开更多

The purpose of employing multi-media technology is to encourage students＇ class participation, giving them explicit and specific impression of abstract contents and cultivating their intuitive grasp of linguistic points. Based on the current study of usage of multi-media technology in class teaching, this paper attempts to investigate mainly on its positive influence of multi-media technology in teaching.展开更多

Without sound, the impact of storytelling is reduced or the story is even not under- standable. Despite the importance of sound, most animators are unfamiliar with sound editing software. Limited budget projects such as independent or student works have difficulty hiring sound professionals to create tailor-made soundtrack. Therefore, we need a suitable sound tool to express their individual ideas. In this paper, we propose an approach using schematic for both computer animation and sound. Our approach provides (1) physical simulation on sound through animation parameters and (2) a new channel for animators to add aesthetic values in sound through their experience of using schematics in existing animation software. We demonstrate our idea through several examples, such as Doppler shift, obstacle effect, importance, energetic, and sputtering effect.展开更多

Despite financial pressure, HIFA has invested heavily in the infi＇aslructure. The classrooms at HIFA can be roughly divided into three kinds： studios, multimedia classrooms and computer labs with reference to ICT. There are three general approaches to the instructional use of the technology at HIFA, namely： learning about computers and the Intemet; learning with computers and the Intemet and learning through computers and the Internet. The utilization oflCT has shaped the art education model of HIFA considerably and has brought about a lot of changes and benefits to the faculty and students. However, its disadvantage may overweigh the advantage unless it is properly harnessed.展开更多

Such new IT mostly comes from foreign countries and the technical manuals about how to learn such new IT and how to use its latest development tools in English. In this paper, combined with previous teaching experience and the development of a large number of networked multimedia, a preliminary study carried out on the interactive network multimedia education platform design patterns, the overall structure and system solutions. As the study is only a tentative teaching experiment based on the collaborative teaching mode, necessary improvement and modification are needed in other teaching practice. According to the curriculum characteristics and teaching situation of computer professional English, propose some teaching innovation scheme in terms of teaching contents and teaching methods, and combine computer professional English with computer professional courses to strengthen student application ability and improve teaching quality effectively.展开更多
