The esthetics of 'grotesque' and its entertaining values have many things in common with the characteristics and properties of animation as a medium of expression. The ways to express grotesque images in animation have expanded its realm of expression with the development of modern image digitalization technologies. The grotesque images that were expressed by the combination of photographs and animations and objet animations have been developing its disharmony in a more realistic manner with full 3D animation technology and realistic motions of virtual characters with motion capture. The subject matter also has become more diverse with the advance of modern scientific civilization. An example is the appearance of Cyborg(cybernetic+organism) characters and the grotesque images in the modern times mainly start to appear in animations dealing with the isolation of human beings among its characteristics. Also, the changes of the expression methods of grotesque images along with the development of visual technology development in the future will transform its methodological forms by changing its expression methods to VR forms and interactive visuals. Thus it is expected that the grotesque images and characteristics will change into a visual genre which emphasizes dehumanization.

최근 영화, 광고, 미디어 전시 등의 분야에서 다양한 특수 효과가 처리된 장면의 연출이 적용되고 있다. 특히, 미디어 전시, 공연 등에서는 관객 혹은 공연자의 움직임에 반응하는 예술적 영상의 인터랙티브 표현들이 시도되고 있다. 이에 본 논문에서는 광고, 전시 등에서 효과적으로 활용될 수 있는 인터랙티브 포토 모자이크(photographic mosaic) 영상을 생성하는 시스템을 제안하였다.. 제안 시스템에서는 관객의 출현을 인지하고, 관객의 얼굴을 자동으로 캡쳐하여 관객의 얼굴 사진을 이용한 모자이크 영상을 실시간으로 생산한다. 이 때, 흥미 유발을 위하여 모자이크를 구성하는 관객의 얼굴 사진 조각들이 움직임을 가지는 작은 사각의 입자로 표현되어 서로가 충돌하며 자연스러운 움직임을 통하여 하나의 영상으로 맞춰가는 모습이 보여지도록 하였다.

오늘날 디스플레이 기술의 진화는 건축물의 외벽은 물론 조형물에 영상을 구현할 수 있게 되었다. 프로젝션 맵핑은 입체감 있는 가상영상을 실내외는 물론 조형물에 덧입힘으로서 새로운 공간으로 탈바꿈시키는 영상표현 방법의 하나이다. 본 연구에서는 프로젝션 맵핑 제작과정에 있어서 색보정이 영상의 입체감에 영향이 미치는지 실험을 통해 검증하고 이를 통하여 프로젝션 맵핑제작에 있어서 효과적인 프로세서에 대한 정보를 제공 하고 확립하는 것이 본 연구의 목적이다. 프로젝션 맵핑은 예술뿐만 아니라 산업전반에 영향력을 주고 있다. 이처럼 새로운 디지털 기술에의한 미디어의 발달과 미디어의 발달에 따른 새로운 표현양식의 등장은 앞으로도 계속될 것이다. 본 연구를 토대로 프로젝션 맵핑 제작에 있어서 유익한 연구의 기초로 활용되었으면 한다.

With the development of informational machinery and tools in the modern industrial society, the image is expressed diversely as tools of informational transmission and artistic communication. This image is revival equipment and transmissional media in which sound and light are comprehensively formed. The image's intuitive and sensational expressivity can revive subjects and express a fiction, a reality, a nonfiction, and a virtual reality as a communication tool that has synchronicity and the medium of meaning. Because of this, the domain of the image will be gradually extended in the future, and the world of cognizance that can be detected across our living space will absorb the image diversely and react. In this context, the investigator examined what influence image media and equipments have in space as spatial equipments, based on the recognition of cerrelation among the image, space, and mankind, namely, the environmental meaning the mage and the space contain. Therefore, this study was conducted from the aspects of relationship establishment between image equipments that are ever expansive to a variety of domains and the space that accommodates the equipments. As study findings, the influences the image equipments have on space and their expressional features are presented in three aspects: 'the expressional medium of mutual synergy','metaphysical ultra-epithelial space constituent',' and 'object'. This study seems to be meaningful in that we can expect the spatial approach method by purposes and spatial layout of image structures, with this study, through analyzing the meaning of relationship between image equipments and space.

Content Based Image Retrieval (CBIR) is to store and retrieve images using the feature description of image contents. In order to support more accurate image retrieval, it has become necessary to develop features that can effectively describe image contents. The commonly used low-level features, such as color, texture, and shape features may not be directly mapped to human visual perception. In addition, such features cannot effectively describe a single image that contains multiple objects of interest. As a result, the research on feature descriptions has shifted to focus on higher-level features, which support representations more similar to human visual perception like spatial relationships between objects. Nevertheless, the prior works on the representation of spatial relations still have shortcomings, particularly with respect to supporting rotational invariance, Rotational invariance is a key requirement for a feature description to provide robust and accurate retrieval of images. This paper proposes a high-level feature named 8AB (8 Angular Bin) that effectively describes the spatial relations of objects in an image while providing rotational invariance. With this representation, a similarity calculation and a retrieval technique are also proposed. In addition, this paper proposes a search-space pruning technique, which supports efficient image retrieval using the 8AB feature. The 8AB feature is incorporated into a CBIR system, and the experiments over both real and synthetic image sets show the effectiveness of 8AB as a high-level feature and the efficiency of the pruning technique.

Simulacra theory as propounded by Jean Baudrillard in his seminal treatise, "Simulacra and Simulation," explores the significance of images, media and art in contemporary culture. Its central theoretical premise is the simulacrum, a sign or symbol that plays a crucial role in constructing perceived reality but which lacks a real-world referent. In Michel Gondry creates simulacra in the form of hallucinatory dream imagery by combining stop-motion animation and live-action elements. As experimental film-making that combines analog and minimum digital technologies, the result is a tour-de-force of synchronization. This study analyzes the film's technique and expressive content and, by adopting simulacra theory as a conceptual framework, aims to provide a better understanding of Gondry's work.

The stippling techniques, which represent objects with numerous points using pen and ink. The previous stippling techniques for Non-Photorsealistc Rendering(NPR) use single-colored points to represent the tone of gray image ur the material of surface. This paper presents a new stippling technique with various colored points based on the analysis of color information. By using the color information of the input image on HSV model, we define the color weight function that allows to determine automatically the number and size of points. The color jittering based on Munsell's color model can generate stippling drawings using various colored points to represent the image. Our color stippling method is expected to be used in many areas such as animation, digital art, video processing and CG tool.

본 논문에서는 노이즈 모델에 기반한 훼손된 얼굴 영상의 인증하는 방법을 제안한다. 제안된 방법은 먼저 학습 단계에서 노이즈 파라미터의 변화에 의해 훼손된 영상을 생성한다. 그 훼손된 영상과 노이즈 파라미터는 PCA에 의해 훼손된 영상과 노이즈 파라미터들의 선형 조합으로 표현된다. 테스트 단계에서는 훼손된 영상으로 LSM(Least-square minimization)방법을 적용하여 훼손된 영상의 노이즌 파라미터를 추정한다. 그리고 추정된 노이즈 파라미터를 가지고 원본 영상으로부터 합성된 영상을 생성하고, 그것을 테스트 영상과 인증한다. 실험 결과는 제안된 방법이 노이즈 파라미터를 정확하게 추정하여 얼굴 인증의 성능 개선 가능성을 보여준다.
