3d 게임 혹은 애니메이션 툴로 제작된 인터렉티브 아트 작품은 디스플레이를 통해 표현 될 때 가상의 입체공간이 시각적 평면 상태로 전달되는 물리적 한계를 가지게 된다. 관람자의 몸의 움직임과 가상현실의 시각적 재현, 물리적 공간에서 물체의 변화와 움직임을 동시에 경험한다면, 다양한 감각과 자극으로 작품의 몰입도를 높이고 전달하고자 하는 내용에 집중도를 높을 수 있다. 이 프로젝트에서는 이러한 복합적인 인터렉션을 통해 현대사회의 가상과 현실의 모호성을 표현하고, 삶의 본질과 현상에 대한 철학적 질문을 제시한다.

In this paper, we describe a novel method for document layout analysis that is based on a Fuzzy Energy Matrix (FEM). A FEM is a two-dimensional matrix that contains the likelihood of text and non-text and is generated through the use of Fuzzy theory. The key idea is to define an Energy map for the document to categorize text and non-text. The proposed mechanism is designed for execution with a low-resolution document image, and hence our method has a fast processing speed. The proposed method has been tested on public ICDAR 2009 datasets to conduct a comparison against other state-of-the-art methods, and it was also tested with Korean documents. The results of the experiment indicate that this scheme achieves superior segmentation accuracy, in terms of both precision and recall, and also requires less time for computation than other state-of-the-art document image analysis methods.

Solid modeling refers to techniques for unambiguous representations of three-dimensional objects. Feature recognition is a sub-discipline focusing on the design and implementation of algorithms for detecting manufacturing information such as holes, slots, etc. in a solid model. Automated feature recognition has been an active research area in stolid modeling for many years, and is considered to be a critical component for CAD/CAM integration. This paper gives a technical overview of the state of the art in feature recognition research. Rather than giving an exhaustive survey, I focus on the three currently dominant feature recognition technologies: graph-based algorithms, volumetric decomposition techniques, and hint-based geometric reasoning. For each approach, I present a detailed description of the algorithms being employed along with some assessments of the technology. I conclude by outlining important open research and development issues.

건물 및 주택의 가구배치나, 인테리어 디자인 등을 신규로 구성하거나 재배치하는 것은 고비용의 작업일 뿐만 아니라, 사용자가 정확히 판단하기 어렵다. 가상현실 시스템을 적용하면 공간적, 물리적 제약에 의해 현실 세계에서는 직접 경험하지 못하는 상황을 간접 체험할 수 있어 재배치에 대한 비용 및 시행착오의 오류를 줄일 수 있다. 따라서 본 논문에서는 EON Studio를 이용하여 건물 내부의 인테리어를 바꿔가며 디스플레이 할 수 있는 실내 인테리어 시스템 프로토타입을 제시하고자 한다. 현실 건물 내부와 가구를 EON Studio를 통해 구축한 후 회전 및 이동을 통해 재배치 도록 하였다. 구현된 시스템을 통해 제안된 인터페이스가 공간 배치 응용 분야에서 유용성 이 있음을 확인하였다.

Ghost imaging (GI) technology is developing rapidly, but there are inevitably some limitations such as the influence of atmospheric turbulence. In this paper, we study a ghost imaging system in atmospheric turbulence and use a gamma-gamma (GG) model to simulate the medium to strong range of turbulence distribution. With a compressed sensing (CS) algorithm and generative adversarial network (GAN), the image can be restored well. We analyze the performance of correlation imaging, the influence of atmospheric turbulence and the restoration algorithm's effects. The restored image's peak signal-to-noise ratio (PSNR) and structural similarity index map (SSIM) increased to 21.9 dB and 0.67 dB, respectively. This proves that deep learning (DL) methods can restore a distorted image well, and it has specific significance for computational imaging in noisy and fuzzy environments.

The art appreciation education is emphasized to develope independent thought and upright value decision in the flood of various image medium. A experience of beauty and a express part related with the sentimental field is focused on directing in the seventh arts curriculum, too. Although the art appreciation education is emphasized, just expressive and functional art texture is still taught in the education spot up to now. Also a appreciative activity is limited simply to describe own feeling intuitionally ; time shortage, difficulty of analysis product, difficulty of guiding appreciation. In this paper I refer that analyze figurative factors of a art product, modify it by applying other program, compare with it and then I develope web base art appreciation system and apply it. As a result I get educational effect. When checking line, form, light and darkness, color, feeling, space and composition of external some factors in a product, formative sense and analytical appreciation is improved.

This study is based on theoretical background about movements of visual communication highlighted in digital age. Such movements are variously expressed in animation with the advancement of media, and their expression has great effect on visual art. Artists' concern and endeavor about movement expression techniques have been continued by impressionism, expressionism, futurism, cubism closely related with the birth of movie from late 19th century to early 20th century. At that time, stationary 2D space in plane screen couldn't express movement or time directly. Later, artists and designers have attempted to approach illusions in pictures or 4 dimension and movements by 2D or 3D computer graphics. The visual image in present digital age is to see, to hear, to feel by timing, so it is necessary for the most efficient way of message communication. And then, it is the time to start new, scientific, and creative study about production techniques of animation and expression of movements, since domestic animation productions are rapidly changed from cell to digital. The aim of this study is to clarify the motive of movement by theoretical inquiry of animation. Various aspects of animation as synthetic art have been examined by mathematical, scientific, and philosophical viewpoint. The results will be useful to the expression of motions for maximization of emotional effect in animation production or basic data of virtual simulation about certain situation. Therefore, such study should be managed as multidisciplinary research in the rapidly changing visual culture paradigm. namely, animation includes much more imaginative & creative power than simple function or techniques, so it has to be recognized as special synthetic art(visual art) constructing an area, the formative art with philosophical viewpoint and scientific principles.

A semiotic approach to modern visual arts has emerged since French post-structuralism was introduced to Anglo -American academics by "deconstruction" or "postmodernism." It views a work of art as a sign, which is its methodical assumption ana at the same time makes its application more accessible In the milieu of modern visual arts'effort to be intimate to with general audience, modern art photography is now faced with the request to be a familar and universal domain instead of being left only in photo books as artistic and academic achievements More specifically, various photo images 1mm such visual media as newspapers TVs, and computer graphics to such megaexhibitions as "Gwangju Biennale," "Media City Seoul," and "Pusan International Art Festival," are main objects of s030y. A coherent and scientific analysis of visual semitotics is still on the way; however, it is an urgent task how to read and interpret a photo image with multiple meanings This study argues that visual semiotics can be a powerful tool to enhance the understanding of art photography. After all, semiotics is a product of age; we live in the age of legibility, that is, of reading the work of art well as the social events and phenomena.rk of art well as the social events and phenomena.
