  • The scalable vector graphics (SVG) standard has allowed the complex bitmap images to be represented by vector based graphics and provided some advantages over the raster based graphics in applications, for example, where scalability is required. This paper presents an algorithmto convert bitmap images into SVG format. The algorithm is an integration of pixel-level triangulation, data dependent triangulation, a new image mesh simplification algorithm, and a polygonization process. Both triangulation techniques enable the image quality (especially the edge features) to be preserved well in the reconstructed image and the simplification and polygonization procedures reduce the size of the SVG file. Experiments confirm the effectiveness of the proposed algorithm.

  • As an emerging technology in Computer graphics areas, SVG(Scalable Vector Graphic) makes it possible to make use of Vector graphics for servicing maps in basic internet browsing environment. SVG based thematic map Internet GIS system implemented by this research is free of special server side GIS mapping system and client side extra technology. It provides high-quality vector map which can interact with the user, template map which can be used for other purpose, glance the future map based on Webservices technologies. Many good characteristics of SVG in mapping at computer screen and reusability of SVG document provide new era of visualzation of geographic information.

  • In this paper, visualization of convolution operation is presented, which is implemented by scalable vector graphics (SVG). Convolution operation is one of the basic essential concepts in the area of signal and image processing. However, it is difficult for students to intuitively understand the operation of convolution since it is mainly based on mathematical representation. We present the visualization of convolution operation and its applications which are implemented by SVG. The effects of the proposed approach have been analyzed by interviews. It has been seen that the proposed visualization of convolution operation could be effectively applied to learn the convolution operation and its applications.

  • Svg(Scalable Vector Graphics) is xml graphic standard recommended by E3C as a language based on xml to express two-dimension graphic. Svg can accommodate all Xml's patency and advantage of interoperability, and can used as various web applications being combined with other xml language. In addition, Svg can be applied to the fields of electronic commerce, geographical information, computer education and advertisement because it can produce high quality of dynamic from real-time data. SVG's application can be enhanced by linking with database. In this paper, we discuss how Svg can be utilized in theater reservation system, not just explaining svg's meaning or ability. Svg added graphic advantage in addition to xml's advantage. This means that svg retains not only graphic element but also xml's softness. It becomes easier to designate seats and add them. Current reservation system provided in general only information on time and price for a ticket, but the system using SVG in this paper provides additional information on position, price, cancellation and purchase availability of seat.

  • A rapid development of Internet is changing users' desire from existing static contents to dynamic and diverse ones. Thus the SVG provides more affluent and sophisticated graphic expressions than an existing method based on bitmap, it can faithfully display vector graphics without scarifying any functions or the problem of device compatibility. In addition, it allows indexing, searching, storing, and sharing by the description of the logical structure of graphics. Since there are, however, very few people who know the complex SVG syntax and make use it, an editing system, which enables users to utilize the SVG graphics easily, has been in need. Therefore, in this thesis, we do research on basic technology on the SVG, design and make an editing system for SVG documents. The system, therefore, provides uses with a user-friendly editing interface and enables them to write graphic objects easily, and generates complex SVG documents automatically.

  • 웹은 플랫폼에 의존하지 않고 모든 사람들이 공통으로 이용할 수 있는 인터페이스를 제공하기 때문에 웹브라우저상에 3차원 의료 데이터를 가시화하여 표현한다면 원격 진단, 의료 교육 등에 이용될 수 있다. 이 논문은 3차원 의료정보를 3차원 의료 볼륨 데이터, 3차원 의료 영상, 볼륨 렌더링 응용의 3 종류로 구분하여 이들을 XML로 표현하는 방법 및 텍스처 맵핑 기반의 디렉트볼륨렌더링(Direct Volume Rendering)을 SVG(Scalable Vector Graphics)으로 표현하여 SVG 뷰어 상에 표시하는 방법을 제안한다. 제안 방법의 실행 결과는 웹 브라우저 상에서 의료데이터의 분석이 가능하게 하고, 또한 볼륨렌더링 응용프로그램을 SVG로 표현, 결과 이미지를 SVG 뷰어로의 표시가 가능하다는 것을 보여준다.

  • 최근 모바일 시스템의 성능이 향상되면서 다양한 형태의 동적인 메뉴 구성과, 메일 및 이차원 지도 등의 표현에 벡터 그래픽을 도입하고 있다. 모바일 기기에서 사용되는 벡터 그래픽 처리 기술은 Flash Lite, SVG(Scalable Vector Graphics)등이 널리 사용되고 있는데 두 가지 모두 소프트웨어 방식으로 사용되고 있다. 매크로미디어사의 Flash Lite는 연산에 많은 메모리를 필요로 하고, SVG는 웹 표준에 맞춘 스크립트 해석 기반으로 구동 속도가 느리다. 모바일 컴퓨팅 환경에서 벡터 그래픽스에 대한 필요성과 사용빈도가 증가함에 따라 메모리를 적게 사용하고 하드웨어 가속기를 지원 할 수 있도록 저 수준의 API(Application Programming Interface)인 OpenVG 1.0을 크로노스 그룹(Khronos Group)에서 제정하였다. 본 논문은 모바일 사용 환경에 맞추어 사용될 수 있도록 OpenVG 1.0에 기반한 API를 구현하고 실험하였다. 구현된 API는 느린 소프트웨어의 한계를 벗어나기 위해 하드웨어 가속기 설계에 적합하도록 각각의 API 블록 및 형태를 하드웨어 파이프라인 형태의 관점에서 설계하였고, 구현된 API를 윈도우즈 환경에서 기능을 검증하였다.

  • The study of Web MGIS(Marine Geographic Information System) based on the SVG(Scalable Vector Graphics) is mainly performed on effective methodologies which transform real world data to computing world data. Web GUI system has its own target on reliable data service by acquisition of geometric information using HYCOM(HYbrid Coordinate Ocean Model), accurate measurement and graphical visualization. This type of raw data visualization can be built without software tools, yet is incredibly useful for interpreting and communicating data. Even simple visualizations can aid in the interpretation of complex hydrodynamic relationships that are frequently encountered in the marine environment. The Web MGIS provides an easy way for hydrodynamic geoscientists to construct complex visualizations that can be viewed with free software. This study proposes a Web GUI MGIS using FVCOM(Finite Volume Coastal Ocean Model). Finally, we design a Marine Web GUI system of Kosrae Coastal Waters integrating above data models. It must adds more ecological information and the various service item for approach more easily in order to user.

  • A Web-based design automation system for concrete slab bridge has been developed to manage the resultant documents as well as to speed up the repetitive design process. Manipulation of engineering drawings in the Web page is one of the critical functions needed for Web-based design automation. Active Server Pages (ASP) is used to that collects design parameters in the database, and eXtensible Markup Language (XML) and XML-based vector graphics are expected to facilitate the representation of engineering drawings in the Web page. In this paper, we present how we used XML and Scalable Vector Graphics (SVG) to compose engineering drawings and represent them in the Web page. XML Data Island we designed to define drawing components turned out effective in manipulating the engineering drawings in the Web page.
