The purpose of this study was to analyze a theoretical frame of expressional area, the characteristics and the effects which is applied to fashion illustration by metonymic theory. The theoretical frame of expressional area was analyzed by category analysis and 150 fashion illustrations from 1900 to 1999 were analyzed by contents analysis. The results of this study were as follows: The expressions of metonymy were categorized by close-up, realistic expression, omission, borrowing of past style, simplification and deconstruction. First, close-up was presented as emphasis of small part of fashion by cutting the scenes, snapshot, emphasis, etc. Second, realistic expression was presented as description of related circumstance with fashion message through perspective and realistic description of circumstance related to figures. Third, omission was presented as seeking of essential core by removing color, pattern, texture or by omitting body and as emphasis of communication about dominant fashion message. Fourth, borrowing of past style was presented as reminding us of background of the past. Fifth, simplification was presented as using of form or color to alleviate tension of object and to restore the essential reality. Sixth, deconstruction was presented as fragmenting of image, flattening of body and clothing, weakness of form, and strength of color. In conclusion, metonymy made by experience system of thinking based on the reality, have extended expressional territory in pre-existing fashion illustration. And these ways not only will provide fashion image as illustrator's subjective intention and theoretical system of expression of message, but also will be useful way to strengthen communication for easier interpretation of fashion illustration.

3D stereoscopic viewing of large scale imagery, such as aerial photography and satellite images, needs different parallaxes relative to the display scale. For example, when a viewer sees a stereoscopic image of aerial photography, the optimal parallax of its zoom-in image should be smaller than that of its zoom-out. Therefore, relative parallax adjustment according to the display scale is required. Merely adjusting the spacing between stereo images is not appropriate because the depths of the whole image are either exaggerated or reduced entirely. This paper focuses on the improving stereoscopic viewing with a single remote sensing image and a digital surface model (DSM). We present the parallax adjustment technique to maximize the 3D realistic effect and the visual comfort. For remote sensing data, DSM height value can be regarded as disparity. There are two possible kinds of methods to adjust the relative parallax with a single image performance. One is the DSM compression technique: the other is an adjustment of the distance between the original image and its stereo-mate. In our approach, we carried out a test to evaluate the optimal distance between a single remote sensing image and its stereo-mate, relative to the viewing scale. Several synthetic stereo-mates according to certain viewing scale were created using a parallel projection model and their anaglyphs were estimated visually. The occlusion of the synthetic stereo-mate was restored by the inpainting method using the fields of experts (FoE) model. With the experiments using QuickBird imagery, we could obtain stereoscopic images with optimized parallax at varied display scales.

Lightscape is a visual rendering software enabling higher dimensional 3D image production using rendering as well. However, direct light simulation showed that more realistic feature of material-specific texture or color could be achieved by adjusting options. Accordingly, this study is to generate optimal values of options and achieve more realistic images by varying such values according to individual materials in order to create better quality simulation images using Lightscape.

This study reflects the aim of analyzing the fashion design connection with ecology. Ecology has been linked to human life through its changing relations with environment. In order to recover eco-system ecology-nature oriented methodology and technology oriented approach will suffice. On the modern design field Green design Recycling and Green marketing resulted in increasing rates of environment-friendly production and an effort to deliver environment-friendly corporate image. Based on above research ecological image on fashion design during the year 1990 to 1995 represents the following conclusion. In the fashion design field natural image primitive image nature -harmonious image material-recyling image culture-recycling image are proposed. In the technology field clean image and high-tech image are proposed. In the marketing field happy image harmonious image serious image and realistic image are proposed.

The wavefront printer records a volume-reflection hologram as a two-dimensional array of elemental holograms from computer-generated holograms (CGHs) displayed on a spatial light modulator (SLM). The wavefront coming from the object is extracted by filtering in the spatial-frequency domain. This paper presents a method to improve color reproduction in a wavefront printer with spatial division of exposures at primary colors, by adaptive partitioning of the SLM in accordance with the color content encoded in the input CGHs, and by the controllable change of exposure times for the recording of primary colors. The method is verified with a color wavefront printer with demagnification of the object beam. The quality of reconstruction achieved by the proposed method proves its efficiency in eliminating the stripe artifacts that are superimposed on reconstructed images in conventional mosaic recording.

인간의 시각경험과 그 재현의 열망은 문명사의 시원에서 그 흔적을 남겨왔다. 당연히 이미지의 역사는 그러한 시간의 깊이에로 소급해야 한다. 그 기원에서 드러나는 이미지의 존재론적 위치는 시각경험의 리얼리티를 핍진적으로 재현하는 데 있었다. 이 열망이 결국 원본과 복제의 차이를 좁히려는 다양한 시도들로 장르화되었다. 핵심은 복제 즉 미메시스의 존재 자격을 원본성에로까지 고양시키는 것이었다. 이것은 눈에 의한 시각경험의 산물인 인상에 어떤 방식으로 리얼리티를 부여하는가라는 기술적 과제로 남겨진다. 고대 그리스에서 테크네에 대한 성찰은 이러한 문제의식과 겹쳐진다. 본 연구가 플라톤의 원본 이데아와 그 복제 미메시스에 대한 논의를 출발의 단초로 삼는 것은 이런 이유에서이다. 결론적으로 말하자면 플라톤이 분류한 '미메시스'가 원본 이데아로부터의 원근에 의해 여러 층위가 나눠지듯이 미메시스를 구현하는 테크네 또한 다양한 위상을 갖춘다는 것이다. 결국 이미지, 혹은 미메시스의 역사는 플라톤 패러다임의 맥락에서 볼 때, '사상(似像)'과 '환상'을 향한 진보의 과정으로 해석할 수 있다. 후대에 구현된 기술적 재현의 다양한 메커니즘은 이러한 성찰을 토대로 하여 이뤄진 결과물이라 할 수 있다.

멀티스크린 영상시스템은 하나의 스크린에 상영되는 영상을 용도에 맞게 여러 화면으로 구성하여 상영할 수 있다. 관객들은 특별한 장치 없이 폭 넓은 실감 영상을 감상할 수 있어 강한 몰입감을 얻을 수 있다. 최근 멀티스크린을 이용한 실감 영상은 Screen X나 Escape와 같은 멀티 프로젝션 기술을 바탕으로 스토리와 정보 전달이 가능한 영화로 제작되고 있다. 또한, 디스플레이의 크기는 점점 대형화 추세이고 화질도 고해상도로 향상되고 있어 HD나 UHD급 디스플레이 여러대를 입체적으로 구성한 디지털 사이니지 형태로 발전을 가속하고 있으나 촬영된 영상을 사용하는 데는 화질열화로 인해 한계가 있다. 이번 연구는 1950년부터 현재까지 멀티스크린 영상의 발전사와 기술적 분석, 제작 방법에 대해 분석하고 멀티스크린을 이용한 영상 콘텐츠 상영 시 발생되는 화질 열화 최소화 방법에 대해 연구한다. 연구 결과를 바탕으로 촬영된 실사 영상은 디지털 사이니지와 같은 고해상도 영상 상영이 가능한 플랫폼에서 실감영상 구현이 가능할 것이라 기대한다.

This study proposes an effective algorithm that can render a realistic image of a lighting environment, especially an automotive rear lamp, using the backward ray tracing method. To producea realistic image similar to that perceived by the human eye, the incident light energy at the eye point estimated by a ray tracing algorithm is represented by XYZ tri-stimulus values, which are then converted into RGB values considering the particular display device.

A technique is described for producing a virtual object with realistic motion. A 3-D human motion model is obtained by applying a developed motion capturing technique to a real human in motion. Factorization method is a technique for recovering 3-D shape of a rigid object from a single video image stream without using camera parameters. The technique is extended for recovering 3-D human motions. The proposed system is composed of three fixed cameras which take video images of a human motion. Three obtained image sequences are analyzed to yield measurement matrices at individual sampling times, and they are merged into a single measurement matrix to which the factorization is applied and the 3-D human motion is recovered ...
