  • In this paper we propose symbol decision method reflecting the color non-uniformity in 3-dimensional color space. By comparing with 2-dimensional color space decision method, we show the superiority of BER performance of the proposed method. Proposed method may reflect the non-uniformity since the symbol decision boundary in color space is transformed from 3D RGB space, and one dimension corresponding to Y value is added. Therefore, we can obtain the better BER performance by using the symbol decision method in 3D color space. In this paper, through numerical simulation, show the superior BER performance of 3D color space symbol decision method compared with 2D color space symbol decision method under AWGN and common mode noise channel.

  • 본 논문에서는 3D 게임이나 가상현실, 인터렉티브 아트 등의 실시간 환경의 컨텐츠 제작에 활용가능한 수묵담채화풍의 렌더링 기법을 제안한다. 제안된 기법은 기존의 3차원 수묵화 렌더링 연구에서는 다루지 않았던, 색채표현법과 그 합성법을 중심으로 연구되었다. 색채표현법의 경우, 일반적으로 삼색을 단계적으로 겹쳐서 표현하는 수묵담채화의 특성에 따라, 실제 그림을 그릴 때에 적용되는 삼색의 혼합방법과 순서가 자동으로 적용될 수 있는 삼색기반 구조를 통해 농담과 질감효과를 표현했으며, 또한 이러한 삼색레이어의 합성을 위해서는 안료의 광학적 성질을 반영하여 실제 회화매체에 가까운 색상을 재현할 수 있는 Kubelka-Munk(KM)모델을 적용한다. 기존의 KM모델은 비사실적 렌더링 연구 분야에서 수채화, 유화 등 서양화를 대상으로 한 색채 합성에 적용되어 왔기 때문에 기존의 연구에서 제시한 방법만으로는 삼색레이어가 겹쳐질 때 나타나는 수묵담채화의 특징과 천연 재료를 사용하는 동양 안료의 색상을 정확히 반영할 수 없었다. 따라서 본 논문에서는 실제 수묵담채화에 이용되는 전통안료의 색상 분석을 통해 KM모델에 적용할 파라미터들을 추출하고, 앞에서 설계한 삼색 기반 구조에 따라 색상을 합성하는 방법을 제시한다.

  • The facade in the street is a unfixed type, thus it is not easy to investigate the characteristic of structures. In addition, a color mainly depends on sensitivity, therefore, it is very difficult to provide the solution of the problems. The purpose of this study is to investigate the relationship between a form of the facade and a color, and to introduce the methodology and the direction of the color scheme for the facade in the street. for the purpose of this study, 47 facades are empirically analyzed. Based upon the results of research analysis, this study try to find out the relationship among the formative continuity of the facade in the street, a color, and the quality of the material. From the results, it suggests the new direction for the image formation of the facade in the street centering around a color. This study concludes that the characteristics of the facade in the street is discontinuous, and the color scheme is not based on the formative continuity. Moreover, the whole street is composed of each strong individual character. In order to harmonious creation of the facade in the street, primary colors and painting colors should be constrained. Finally, the color scheme based on the formative continuity of the facade in the street should be carefully considered.

  • A new method is proposed for the design of the dichroic mirrors in 3-LCD projection systems for color separation/composition. Rather than simply basing the color performance criterion on luminance or chromatic saturation only, the optimum design parameters can be found by maximizing the perceived color gamut in a 3-D uniform color space. In this method, the half-power wavelengths were optimized by maximizing the volume of the reproducible color gamut in a CIELUV uniform color space for 2 typical viewing conditions, with proper colorimetric analysis of color reproduction in 3-LCD projection systems.

  • This study was carried out for the purpose of analysis correlations between street furniture design elements and preference of street furniture. This research analyzed the various street furniture set on Ilsan new town street, which are rest, hygiene, light, information, sale, traffic, and landscape. This study has processed by analysing street furniture literature investigation and consideration of theory. First, for analysed effect of street furniture element, has been appear as element 'relaxation facilities', 'information facilities', landscape facilities' mainly effect on street. Specially, 'rest', 'landscape', 'information' in order had a major influence on scenery. Each kind of 'chair elements' in rest facilities, 'sign board' in information facilities, 'sculpture', 'fountain' in 'landscape facilities' has analyzed as the main elements in the landscape affinity property affecting factor. Second, the results of analyzed landscape elements (shape, colour, texture, scale) affect to the affinity of street furniture. chair which are included in rest facilities affect "texture", "form", "scale", "color" in the order of preference of the molding design elements that influence landscape. Particularly, showed statistically significant on 'colour' element affecting the landscape preference than the other three elements. It means as the chair element which is rest facilities mainly affect on preferences, rather than texture, form, scale, colour. Monument in the landscape associated with a preference 'colour', 'shape', 'texture' 'scale' and appears to be in order of impact so we could get the consequence like chair and rest facilities show different aspects of the respectively. It means, visual element which are colour and shape significantly impact on landscape preferences. Third, information facilities such as signboard formative elements of landscape design preferences and correlation with negative showed that the correlation. That mean if the sign board is very negative influence on landscape preferences and the correlations of the design formative elements appear in order of 'scale', 'colour', 'texture'. It also means that the 'scale' namely the size of advertising material and colour are adversely affected in terms of landscape. As these results, when design street furniture as the street scenery, facilities according to the kind of the shape element and need to focus on relative shape element according to the kind of facilities difference. Finally, so far as to clarify the street furniture, mainly 'function' and 'system' classification shows undesirable in outdoor scape. Thus, performed studies in relationship with landscape, classify 'kind of facilities' is more desirable than 'system'.

  • 3-D image modeling is in high demand for automated visual inspection and non-destructive testing. It also can be useful in biomedical research, medical therapy, surgery planning, and simulation of critical surgery (i.e. cranio-facial). Image processing and image analysis are used to enhance and classify medical volumetric data. Analyzing medical volumetric data is very difficult In this paper, we propose a new image modeling method based on tetrahedrization to improve the visualization of three-dimensional medical volumetric data. In this method, the trivariate piecewise linear interpolation is applied through the constructed tetrahedral domain. Also, visualization methods including iso-surface, color contouring, and slicing are discussed. This method can be useful to the correct and speedy analysis of medical volumetric data, because it doesn't have the ambiguity problem of Marching Cubes algorithm and achieves the data reduction. We expect to compensate the degradation of an accuracy by using an adaptive sub-division of tetrahedrization based on least squares fitting.

  • Usual1y, common color systems have been expressed with two dimensional method such as books. We think that the three dimensional presentation of color is very useful to know the characteristics of the color palette for interior design. And, it might be convenient far planning the colors of interior design. This paper deals with the method of 3D presentation. We used AutoCAD 2000 and 3dMax 4.0 in modeling the color system. By presenting which parts of the munsell color system used in the colors which have appeared in interior design three dimensionally, the guideline fur the interior designers can be suggested.
