본 논문에서는 특별한 스튜디오 조명이 아닌 가정용 혹은 학교용 조명 하에서 동작하는 감정 표현이 가능한 그림자 놀이 도구를 소개한다. 이 놀이는 사용자의 실사로부터 추출된 가상 그림자에 사용자의 동작에 따라 실시간으로 반응하는 가상 표정 애니메이션 캐릭터를 투영한다. 이 놀이 도구는 행위전시 등의 공연 환경뿐만 아니라 가정, 학교 등의 일상 환경에서도 동작이 가능하도록 설계되었다. 따라서 가장 일반적인 조명의 하나인 가정용 형광등과 백열등 환경을 가정하였고, 배경에 대해서는 어떤 제약도 가정하지 않았다. 사용자의 실사를 구분하는 과정에는 배경 차분화 기법을 사용하였고, 빛의 산란 및 실제 그림자의 영향 등으로 인한 잡음을 최소화하기 위해 몇 가지 잡음 제거 알고리즘을 결합하여 적용하였다. 이 도구에서 가상 그림자의 표정 애니메이션은 사용자의 손동작에 따라 변화하며, 손동작 및 머리 위치의 추적을 위해 새로이 고안한 자질 기반 추적 기법을 적용하였다. 이 도구는 공연장에서의 인터렉티브 미디어 아트 전시 또는 공연, 아동 대상의 미술 교육, 예술치료 등의 분야에 활용될 수 있을 것으로 판단된다.

In this paper, we implemented a web-based 3D virtual pottery gallery Using VR authoring tools. With this system, we expect to cause learning motives and Provide more realistic and interactive learning space. Out system was implemented by making panorama images and 3D object modules using Photo Vista. Object Modeler and Reality Studio. Users can connect to this web site(http://artstory.x-y.net), rotate a pottery panoramically, and zoom it in or out. We designed this virtual gallery can have beneficial influence on students' aesthetic aspects through realistic work appreciations in their art education processes.

The purpose of this study is to investigate how to express Surrealism techniques in Chris Landreth who is very famous for 3D short such as Ryan. The case works are focused on 'the end', Chris Landreth's early work. He set up situation of the absurd and describes human being's alienation in animation. A phase of social life is not only revealed with vivid colors and his own surrealism techniques but communication capacity of 3D animation is also shown. Digital Technology, reproducing impossible images is not all about 3D animation. As well as this, it is not far away the way of creating arts. 3D animation will be shown the new possibilities with extension and harmony of all kinds of arts expression.

Nowadays, active teachers expend much time and effort in preparing for classes. Especially, the basic formative calsses in art education have much effect when they are done with a lot of material(plaster casts, etc.) and lighting effect, but not in real. Proposed web-based learning instrument makes possible basic formative classes with simple operation by loading several materials and lighting operator on the web. In this paper, we propose web-based learning instrument to improve basic formative classes. Students will easily be able to express shadow and shade by lights with this web-based learning instrument in basic formative classes.

Probabilistic approach is applied to the experiment of Probability Density Function to get the information. Especially this method will be useful to make the montage to compare similarity. But in the case of art painting, it is more difficult than montage image. In this case, we should study the habit of painter with characteristic point in the paintings. Especially we will study characteristic point in the oil paintings to decide truth or falsehood in this paper.

The purpose of this study was to develop an infographic-based STEAM program for high school students and test its effectiveness. In this study, we converged high school 'art' education with 'Korean language' and 'mathematics.' The program was divided into four phases. The effectiveness of the program was analyzed by conducting matched pair t-test for 377 students at a girl's high school in Seoul before and after the program. The study found that the students' self-concept on mathematics and their attitude towards choosing science and engineering career showed significant increases after the program. By connecting high school courses through data visualization based on cognitive information design, findings from this study suggest that our infographic-based STEAM program should be implemented more frequently at high schools.

대체 불가능한 토큰을 의미하는 NFT 는 블록 체인 기반 기술 중 하나로 소유권과 거래 이력이 블록 체인에 기록이 된다는 장점을 지녀 미술 작품 거래에도 활발히 활용되고 있다. 하지만 현재 NFT 작품 거래 시장은 주식거래와 같이 회전율과 거래량을 중점으로 투기성이 짙으며, 작품의 섬네일 이미지만으로 거래 의사를 판단하는 경우가 많다는 문제점이 대두되고 있다. 따라서 작품의 다양한 특성에 대한 고려가 함께 이루어질 필요가 있다. 본 논문은 작품의 다양한 변수를 수집하여 최적의 변수 조합을 찾아내고, 이미지 전이 학습과 생성 알고리즘을 활용해 다양한 변수가 가격에 미치는 영향을 알아보고자 했다. 연구 결과 이미지 만을 활용한 가격 예측은 정확도가 높지 않다는 사실을 확인하였고 작품이 가진 여러 특성을 변수로 한 정형 데이터의 가격 예측 정확도가 더 높은 것을 알 수 있었다. 또한 생성 알고리즘을 통해 새로운 특성 조합의 작품들을 만들었고 가격을 수치 예측해보았다. 이를 실제 작가의 작품의 가격과 가격의 변동 추이를 대조해 작가의 작품 판매 가격 평균치 이상인 작품의 특성을 확인할 수 있었다.

This study adopted a deconstructionist approach to utilise expressive features of architecture of Suzhou Chinese classical gardens to conduct an empirical study that combined traditional elements with modern design processes. Firstly, concepts and characteristics of Chinese classical primary forest and deconstructionism are deeply understood. Their artistic value and modern application potential are explored. Artistic layers of classical primary forest and deconstructionism were analysed to investigate their sculptural and expressive characteristics and to explore new design measures. Based on this, a deconstructivist design process was utilised to develop an experimental fashion design process that utilized the classical Chinese image of Wenlim. The outcome of this research was a 3D virtual fashion design, which could present new design possibilities. It is hoped that this study will provide an easy and accurate analytical framework for further research on traditional Chinese images in contemporary fashion.

Conventional vibration-measurement methods used for vibration testing typically employ accelerometers, which offer the significant advantage of accurately measuring vibrations at specific positions. However, they can only measure one point at a time as simultaneously measurements of multiple points can be economically disadvantageous. This study aims to overcome these limitations by analyzing the vibration outputs of accelerometers attached to a product and those obtained through image processing. The analysis involved assessing the measurement uncertainties and verifying the low-frequency vibration testing according to KS standards. The results validated and confirmed the reliability of the proposed camera-based image-processing vibration-measurement method, which exhibited a notable vibration-detection performance and measurement errors within 5% compared to accelerometers for low-frequency vibrations. This method has the potential for application across various vibration-response and durability evaluations. Future research should focus on expanding it to high-frequency vibration testing using high-speed cameras and further enhancing image-based vibration-analysis techniques.

The mobile phone and wireless network, location based technology and other newly introduced technologies and communication media gave birth to the new terminology "ubiquitous" and are changing our daily life. Influence of such technologies and communication media is not an exception in the arts. New media art pieces using these technologies are increasing, and taking on the characteristics of public art within a wider scope of a city as a backdrop, beyond the traditional boundaries of art galleries. Of such art, locative media art using locative media has a closer relationship with city space than any other form of an, and makes various attempts to allow the spectator to reinterpret and experience city space and induce communication. These characteristics of locative media art can be considered as a method that can solve quality problems of the city space, especially the loss of the sense of place and the absence of communication. is one such locative media project with a purpose of solving quality problems of city space, especially the recovery of commercial sites and inducing communication. This project uses the paths of the city as its canvas, movement of people as its brush, the color of the roads as its pallet, and by allowing the partakers to draw paths of their own and to share their paths with others. People are encouraged to share stories about their paths. The project proceeds using barcodes that are frequently used commercially. When users wish to create their own place, they can enter their place and colors of their choice using input devices installed in the city space. Paths that are created through such a process will be displayed in public areas throughout the city, shared with others, and can create and share a stories about the city using on/off-line media.
