  • Recently, the research about color matching for the input/output devices of printing process is progressing rapidly by the digitization. The calibration method of flatbed scanner widely used as an input device for prepress process is especially important for color proofing of high quality color prints. In this paper, scanner calibration method using 3-dimensional look-up table and tetrahedral interpolation was examined and analysed comparatively on the three kinds of original copies, such as photograph, dye sublimation proof and ink jet print for IT8.T/2 target.

  • Method for 3D reconstruction from image points and geometric clues can be roughly classified as "model-based" and "constraint-based". We present a new method to reconstruct from one image a scene using depth-point. The our method is benchmarked synthetic data and its effectiveness is shown on photograph data.

  • 본 연구의 목표는 GPS(Global Positioning System)을 이용한 3차원 네비게이션 시스템을 개발하여 원하는 목적지까지의 경로를 실시간으로 도로 전경과 동일한 3차원 영상으로 살펴봄으로써 운전자를 효과적으로 도울 수 있도록 하는 것이다. 실제 도로에서 일정 간격을 두고 촬영한 파노라마 실사 영상에 TIP 기법을 적용하여 가상환경을 구축하고 이들 사이의 부드러운 전이를 통해 사진과 같은 품질의 3차원 영상을 보여준다. 개발된 시스템은 2차원 네비게이션 모듈을 가지며 최적 경로 탐색 및 도로 상황 예측 기능을 제공한다.

  • Computer Graphic design was developed for printed media and its way of expression has been progressed di\ulcornerversely. Especially, the practices of computer graphic are used in textile design enterprise. The use of computer graphics in courses of textile design was produced by various si$$\mu$ations of colors, size and shape in patterns. Then the completed textile was presented as photograph. This paper describes patterns of two dimensions, cloths of three dimensions in use of softwares-TIPS, LUMENCE, FREE STYLE andTOPAS. As mentioned above, we can design fashion with easy by using computer graphics.

  • This paper showed that the policy power of the Chinese government in the 1950s was directly linked to the development of housing construction. The author of this study conducted on-site surveys of several collective houses built from 1949 to 1960 that are still standing to photograph and investigate the status of these residential buildings.

  • Flame spreading over liquid fuel surface has been investigated using thermocouple and schlieren photograph. Without forced convection, it was clearly found that the flame spreading is mainly controlled by surface flow which is maybe generated by change of surface tension. Furthermore, the radiative heat transfer is dominant over a conductive heat transfer in kerosene. But the latter was found more influential than the former in diesel. Oscillation of flame spreading was found. It maybe cause of surface flow.

  • 오늘날 우리나라의 지적도면의 경우 2차원의 지적정보를 제공하고 있어서 일반인들이 이해하기가 어렵고 개별 필지의 경계나 면적 등에 대한 구체적 정보의 접근은 더욱 더 어렵다. 최근 각 지자체에서 항공사진과 지적도면을 연계한 3차원 지적정보를 제공하고 있어 아주 일반인에게 만족도가 높은 반면 지자체에서는 이러한 서비스를 제공하기 위해 항공사진의 구입을 위한 비용이 지출되고 있다. 최근 3치원의 지적구현을 위한 다양한 방법이 개발중에 있으나 일반인들에게 있어 현재까지 많이 이용되고 있는 서비스의 제공은 Google Earth의 3차원 영상이며 최근 각종 연구들이 Google Earth Image Maps을 이용하여 활발하게 진행되고 있다. 따라서 본 연구의 목적은 현실감 있는 3차원의 입체적인 정보를 실시간으로 제공하며, 그 사용 및 제공에 있어 지방자치단체에서의 예산적인 측면에서 더 경제성이 있는 Google Earth Web상의 영상을 이용하여 현재의 연속지적도와 Google Earth 영상과의 중첩을 통해 상이한 좌표체계간 중첩정확도를 비교분석하여 향후 지자체의 이용가능성이나 활용방안 및 방향을 제공하였다.

  • The purpose of this study is to elucidate that photo, which has been used as original photo's purpose of information transfer in modern age, is now used as romantic reproduction which is the communication methods of architect's idea and thought through photographic vision which is beyond photograph own capabilities. The photos of Mies van der Rohe and Le Corbusier's architectural works are taken as an example for studying and analysing the way of deliverying the concept of creative work in the functional spaces in the modern era. It looked at the way of modern archirecture configuration, which architects wanted to show by pictures, such as concurrency, movement, sense of exhibition and concept of time-space and planarity on photographic vision such as multiview, movement, daily life exclusion, scenography and perspective loss. Reflecting that, I presents Le Corbusier and Mies van der Rohe's intention through photo by analyzing their picture of architecture by way of photograph techniques-camera position moving, over exposure, photomontage, silhouette technic and overlap technic. Mies van der Rohe and Le corbusier demonstrated the change and manipulation of the their architectural photos in different point of view. They express their architectural theories by photos of their works and overcome the limitation of expression of constructed building designed by them. The photos of architects's works in the case study with photos and descriptions introduce to their design concept. The design concept of the architects have become ideal concept for many contemporary architects and keep reproducing through the photos of their architectural works.
