The article deals with the reality subject of animations. Animations are created on the basis of fantasy. Disney's introduction of the narratives and styles of live action film into the field of animation, which laid a foundation for the hyper-reality animation, has produced an unintended consequence of marginalizing other animation genres which have emphasized fantasy through free experimentations of various images. A combination of Disney's world view of hyper-reality with later-developed 3D computer animation technology has made fantastic figures and spaces much more real than the real ones, and succeeded in creating a matrix of simulacre, a world of mere copies without the original.

최근 3D영화의 흥행과 더불어 3D 영상제작 기술들이 높은 관심을 받고 있다. 변이 정보를 획득하기 위한, 스테레오 매칭에 관한 분야는 꾸준히 연구가 되고 있는 분야이다. 그 중에서도 지역적 방법은 구현의 용이성과 낮은 계산복잡도로 인하여 많은 연구가 진행되고 있다. 하지만 대부분의 지역적 방법들은 영상이 외부환경에 변형되었을 때의 경우를 고려하지 않고 있기 때문에, 외부환경에 의해 많이 변형된 영상에 대해서는 제대로 된 변이 정보를 추출해내지 못한다. 본 논문에서는 양쪽 영상에서 픽셀간의 차이를 이용하여 서로 대응되는 영역을 찾는 스테레오 매칭 기법을 제안한다. 제안하는 기법은 조명과 같은 외부요소에 강인한 특징을 가진다. 이 기법은 전 처리나 후처리 과정에서 부가적인 작업의 수행 없이 기법 자체만으로 외부요소에 대한 보상을 실행한다는 면에서 장점을 가진다. 다양한 영상에서 변이를 추출하는 실험 결과, 단계적 조명 변화에 대해서도 대조군 방법과 비교하여 균일한 변이 영상을 획득할 수 있었다.

최근 컴퓨터비전 기술을 이용하는 새로운 패러다임의 마커프리 모션캡처 기술이 미국의 MIT, CMU, MS, 일본의 ATR, MERL, 영국의 Oxford 대학 등에서 개발되고 있다. 마커프리 모션캡처는 연기자의 몸에 마커나 센서를 부착하지 않으며 특별한 조명이 필요 없으므로, 애니메이션 제작뿐만 아니라 일반인을 대상으로 하는 동작 인터페이스분야로의 확대 적용이 가능한 모션캡처 방식이다. ETRI에서는 여러 응용 분야에 모션인터페이스로 활용할 수 있는 환경 변화에 강인한 마커프리 모션캡처 시스템을 개발하고 있다. 몸에 마커나 센서를 부착하지 않은 자유 복장 상태의 동작자에 대해 조명 조건 변화 및 배경 변화에 강건하게 실시간 모션캡처 할 수 있는 기술 개발을 목표로 한다. 본 연구 개발이 성공한다면, 2007년에 876억 달러 규모로 확대될 전망인 영화, 방송물, 게임 등을 포함한 세계 영상 콘텐츠 시장에서 핵심 요소 기술 역할을 할 것이다. 그리고, 차세대 3D OS에서는 직관적 3D 포인팅 수단으로 활용될 수 있을 것이며, 2004년에 18,600만 대가 출고된 PC 시장을 고려하면 폭발적 수요가 예측된다.

영화, 애니메이션, 게임 등 디지털 문화 컨텐츠에서 의상을 입은 캐릭터들의 사실성이 강조되는데, 기존의 패션 CAD나 의상 애니메이션 소프트웨어들은 디자인에 있어서 여러 단계의 작업을 거쳐야 하고 의상 디자인의 전문성을 요구한다 특히, 최근 우리 문화 원형의 디지털 컨텐츠화로 디지털 한복의 수요가 증가하고 있으며, 한복은 재단이나 착용방식 등에서 양복과는 구성학적 차이점을 지님에도 불구하고 디지털 한복 제작을 위한 전문 시뮬레이션 도구는 전무하다. 따라서, 본 연구에서는 전통적인 한복의 제작에서 사용하는 신체 치수 측정방법과 옷본 및 체형에 따른 사이즈 조정 방법을 지식베이스로 구축하였다. 이를 통해 한복에 대한 사전 지식이 업는 사용자들도 가상 캐릭터에 쉽게 한복을 착용 시킬 수 있는 지식 기반 한복 드레이핑 방법을 제안한다.

In this paper, we propose a low-cost and compact motion capture system which enables to play motion games in PS2(Play Station 2). Recently, motion capture systems which are being used as a part in film producing and making games are too expensive and enormous systems. Now days, motion games using common USB camera are slow and have two-dimension recognition. But PSD sensor has a few good points, such as fast and low-cost. In recently year, 3D motion capture systems using 2D PSD (Position Sensitive Detector) optic sensor for motion capturing have been developed. One is Multi-PSD motion capture system applying stereo vision and another is Single-PSD motion capture system applying optical theory ship. But there are some problems to apply them to motion games. The Multi-PSD is high-cost and complicated because of using two more PSD Camera. It is so difficult to make markers having omni-direction equal intensity in Single-PSD. In this research, we propose a new theory that solves aforementioned problems. It can measure 3D coordination if separated two marker's intensity is equal to. We made a system based on this theory and experimented for performance capability. As a result, we were able to develop a motion capture system which is a single, low-cost, fast, compact, wide-angle and an adaptable motion games. The developed system is expected to be useful in animation, movies and games.

Game industry is one of the most popular sector in the world cultural industries in the digital era. 2D and 3D Animation with development of computer technology it. Because Animation needs to show real motion image. The computer hardware and software technique quick change it leads and 2D and 3D the animation is the tendency which provides the growth which is infinite. But recently Game graphic design have a trend 3D Game that is absorbed and easy handling. 2D Game Character is changing to 3D Game Character more and more. This thesis have significant the real motion capture of 3D Game Character and the types, the shapes of 3D Game Character animation. First of all this thesis will define about 3D Game Character as well it will be show examples of real motion capture also it will proposal data of real motion capture. Therefore it will be bring the high technology Animation industry with Digital Contents industry. also hope for the growth of Game Character Animation process and 3D Game Character Animation in Game industry as well contents industry.

In this paper, microstrip antenna using multi-layer and folded structure for GPS application is presented for aircraft loading. Existing microstrip patch antenna used dielectric of high specific inductive capacity to miniaturize that cause smaller bandwidth and decline of efficiency due to dielectric loss. To compensate the existing flaws, Rogers TMM 10i(dielectric constant=9.8, loss tangent=0.002) is used for multi-layer dielectric miniaturization, and we construct folded radiating element on the surface of the dielectric applying perturbation effect. The antenna is designed in the bandwidth of GPS $L_1$ band, and the size of the antenna's radiating element is $20.3mm{\times}19.93mm$, and it gets 94.2% miniaturized characteristic of basic ${\lambda}/2$ microstrip patch antenna. Also the measured -10 dB bandwidth is 32.3 MHz(2.05%), 3 dB axial ratio bandwidth is 6.7 MHz(0.43%). Measured radiation patterns was maximum gain of 0.56 dBi at x axis polarization, 1.23 dBi at y axis polarization.

The industry of digital culture contents has resulted in the high growth of added value at the area of game and movie in 2004 but the markets of animation character, and music disc have been weaken. Animation industries in Digital culture contents have attracted the attention of the people as the business of multi culture contents which has the possibility to expend and to enhance the added value nut only for the field of image and character business but also for the area of the copy right on. The stable structure of market, however, has not been settked down except a few of successful projects due to the rapid decline of 2D animation and the strong market of 3D in overseas. The purpose of this study is to analyze and research the basic logic of the market structure at the domestic business of 3D animation. In addition this paper is to suggest an alternative in terms of benchmarkin in overseas. It could be expected to achieve the effective production in this field, if the result of this study could be applied to the related world as a development model at the area of 3D animation in digital culture contents.

The technology and concept of multimedia expands with the rapid growth of Digital technology. Digital broadcasting has already begun and movie industry is also switching the way of visualization from analog to digital. Image compositing is the core of the computer graphics related multimedia technology. Currently, various computer graphic technologies are being developed. Nevertheless, image compositing are being done manually because of not only the expensiveness image compositing equipments, but also the lack of experts in this area. This paper present a new image compositing technique for 3-Dimensional graphics and digital sources. A 2-Dimensional subject which will be used as a background was expanded into a 3-Dimensional by using the tracking technique. Thereafter, Effective image compositing has been obtained by precisely cooperating digital source images and 3-Dimensional model using 3-Dimensional graphics editing tool.
