  • 이미지 데이터는 표현 방식에 따라서 비트맵과 벡터 방식으로 나누어진다. 비트맵 방식은 이미지 데이터를 픽셀이라는 2차원 맵으로 구성한 것이며, 벡터방식은 주어진 2차원 또는 3차원 공간에 선이나 형상을 그리기 위해 일련의 명령어나 수학적 표현으로 나타낸 것이다. 따라서 서로 다른 방식의 이미지를 제작 및 편집하고 자 하는 경우에는 각기 다근 응용프로그램을 사용해야 하는 문제점이 있다. 본 논문에서는 비트맵과 벡터 방식을 혼합하여 하나의 응용프로그램에서 이미지의 제작 및 편집이 가능한 이미지 편집 도구의 설계 및 구현 방법에 대하여 기술하였다.

  • The purpose of this study is to define the fundamentals of one symbolic concept, so calles vestment-sign, based on the logical relationship of sign system about the trichotomy by charles S. Peice's sign concept for the communication system of meaning in the non-linguistic image domain. To prove the argument of vestment-sign, I selected 3 type of vestment language by styliste, Elsa Schiaparel-li. The third image vestmental chosen here, titled“Larme-Illusion(1938)”,printed by Salvad-or Dali will produce one symbolic proposition as a logical result which is generated and developed through the interpretation of other images. First of all the text, which is manifested by Elsa Schiaparelli's first image vestmental, tit-led“Notation Musical(1937)”and is symbolized as one category in the representation of the form, is regarded symbolic and metaphorical from a standpoint that the title and the meaning is connected to the form. The second image vestment, titled“Ruches Noirs(1938)”represents externally splendid feminity man-ifested by the symbolic and metaphorical expression. And the purity of sensitivity aiming to humanity in the detail of the poetic feeling of naturalism makes us imagine the battle fild of furious sensitivity. Like as the result of the battle, the third image stimulated our eyesight with the“absence”of dressing function. The proposition of the text,《Death》which the third image delivers, constructs sign system to bring up a meaning with the disappearance of physical“signifier”. This establishment of the symbolic concept presents the etymological authority of symbol generation called“Design”.

  • 디지털 몰핑은 영화의 내러티브를 효과적으로 표현하면서 현실 넘어서는 상상을 사실로 구현한다. <블랙 스완>(2013)에서 디지털적으로 구현된 몰핑 이미지는 포스트 시네마로서 오늘날 영화의 특징을 잘 보여주고 있는데, 컴퓨터 기술을 적극적으로 활용해 마술 같은 환각적 이미지를 제공한다. 디지털 몰핑 기술은 주인공이 발레를 추는 동안 기괴하게 변형되어 가는 신체를 현실과 환영이 구분되지 않게 제시함으로써 충격을 준다. 이러한 이미지는 어트랙션 효과로 그치지 않고 신자유주의 시대의 강도를 정동의 흐름으로 가시화해 낸다. 신체 변형의 기이한 효과는 신자유주의 현실의 징후인 것이다. 또한 이러한 몰핑 이미지는 파트리샤 피스터스가 말한 신경-이미지 체제의 부상을 말해준다. 디지털 스크린에 나타난 신경 병리학적인 양상들은 신경-이미지에 해당되는 것으로, 들뢰즈의 시간-이미지 체제를 넘어서 미래의 시간성을 띤다. <블랙 스완>의 몰핑의 경우 니나의 신체가 흑조와 혼종화 되어서 계속적으로 변화하는 동안 신경-이미지적인 특성이 두드러지게 나타난다. 신경 이미지로서 이 영화의 디지털 몰핑은 주체가 겪는 현실의 충격을 조절하는 효과를 지닌다. 이 영화의 몰핑은 디지털 시대의 사회적 통제의 효과이자 그 통제를 조절하는 포스트 시네마의 역량을 보여주고 있다.

  • Lighting made interior space visible and to recognize space itself. Sp9ace and form are established not themselves , but lighting. and dextrous treatment of natural light accomplished poeteic space. Inflowing of lighting in interior space is main factor to decide space character and image . That was recognized in interior space through many centries. At this point, this study was described for that present inflowing of lighting adapting space character and right method in lighting program. The present study is to present the planning method of the most appropriate and the most rational natural lighting in planing for lighting. Under this premise the followings are made ; I. An introduction , the purpose, the sphere, and the method of this study are stated. II, The present writer studied the general characteristics of natural lighting. III. this author studied the factor of decision on control and representation skill of lighting along the following. IV. Analyzing interior space in which the natural lighting is introduced through some literature and case studies. Physics, psychology, structure, equipment, material. V.

  • The propose of this study analyze an expression method of a surface in commercial buildings, and it is to show an example of a surface design in Manhattan. In particular, I focus on the following three categories : representation element of surface image : materials and structure method, the property of transparency, and an electronic surface and media screen. Unlike the past era in which surface design in commercial buildings was viewed just as a mean ornament, it has become more important in the presently era because diverse expression technologies in surface design makes architects express there creative ideas. Besides, the diversity of surface design expands the concept of cultural space as it provides various graphic element that human desire for multi-cultures. So diversity of surface will accelerate.

  • 본 논문에서는 효율적인 암묵적 지식을 표현하기위한 도구로써 개념매핑기법에 대해 기술을 하고 있다. 개념매핑기법은 비형식적인 것에서부터 형식적인기법까지 다양하다. 형식적개념매핑은 사용이 용이하지만 컴퓨터 처리능력이 없다. 반면에 비형식적 개념매핑은 추론능력은 있으나 사용이 어렵다는 단점이 있다. 따라서 미래의 지식매핑시스템은 형식적ㆍ비형식적 개념기법의 장점을 모두 고려해야 할 것으로 보인다.

  • In this paper, we implemented a sign language communication system between korean and japanese using 3D model. Unitl now, we have developed the system through 2D image. The system, however, has some drawbacks base don the limitations of 2D model. Especially it is not comprehensive in the sign language gesture including forward or backward movements becasue it can only display a front view. Therefore, we employed a 3D model for the representation of sign language. The proposed communication system si implemented with windows 95 visual C++ 5.0 imported open inventor library on pentium 233 system. Experimented results show that the 3D system can solve the problems in 2D representation.

  • In this paper, we propose a computer environment class for student's mental representations about non-Euclidean geometry. Through the software Cinderella, students construct knowledge about non-Euclidean geometry and recognize differentness between Euclidean and non-Euclidean geometry. Also they recognize an existence of non-Euclidean geometry newly and its mental representations with images represented in Cinderella. In geometry class, we make students can use many representations systematically and can figure a visual internal image by emphasizing a transform process. And then students can reason about non-Euclidean geometry.

  • Physically-based rendering is an image synthesis technique based on simulation of physical interactions between light and surface materials. Since generated images are highly photorealistic, physically-based rendering has become an indispensable tool in advanced design visualization for manufacturing and architecture as well as in film VFX and animations. Especially, BRDF (bidirectional reflectance distribution function) is critical in realistic visualization of materials since it models how an incoming light is reflected on the surface in terms of intensity and outgoing angles. In this paper, we introduce techniques to represent BRDF as B-spline volumes and to utilize them in physically-based rendering. We show that B-spline volume BRDF (BVB) representation is suitable for measured BRDFs due to its compact size without quality loss in rendering. Moreover, various CAGD techniques can be applied to B-spline volume BRDFs for further controls such as refinement and blending.

  • This paper presents a recognition method which interprets 3-D object in terms of several silhouettes of quadtree and octree. Object representation used in object matching should be invariant with respect to locatin and orientation of the object. Generalized octree is projected on to image plane along the principal axes. Regular octree is made from orthogonal directions, but generalized octree is independent to viewing directions. Recognition process is achieved in two-stage matching. The quadtrees and octrees of unknown object with minimum dissimilarities are matched with the quadtrees and octrees of the models. So as to verify efficiency of 3-D object representation and accuracy of object recognition, experiments are performed for 14 different type of geometrical models and its results have been shown.
