본 논문에서는 사용자가 입력한 사람의 신체 모델과 모델에 입혀질 옷의 두 이미지를 입력으로 하여 2D상에서 옷과 모델이 잘 어울리게 입혀지는 가상의 드레스 업(Dress up)시스템을 제안한다. 첫 번째 단계에서는 골격 구조의 조인트 정보를 이용하여 옷 이미지를 크게 변형시킨다. 다음으로 옷의 경계에 있는 점들을 샘플링 하여 모델의 경계에 있는 점과 매칭 시키고 그 점들을 이용해 최적화 단계를 거쳐 최종적인 피팅 결과를 도출해 낸다. 두 단계를 거쳐 피팅 된 옷의 경우 평면적으로 보이기 때문에 부자연스러운 결과를 보이게 되므로 자연스러운 렌더링 결과를 위해서 이를 3D로 재구성 (reconstruction)시킨다. 재구성된 3D구조로부터 쉐이딩 정보를 가져와 다시 2D상에서 렌더링을 함으로써 최종적인 결과를 도출하게 된다. 본 연구에서 제안된 시스템을 통해 2D 기반의 가상 옷 시뮬레이션 결과를 얻을 수 있게된다.

This study was attempted to investigate the possibilities of fitness evaluation of virtual model using 3D clothes modeling software. For the purpose, two one-piece dresses were made with two kinds of patterns using Qualoth program, and then each dress was fitted to a real model and a virtual model, and the results were compared and discussed. The result of this study was as follows. First, the fitness evaluation of real model showed a significant difference only at a little difference in figures (1-2.5cm) of the pattern, while any significant difference in appearance was not found in case of a virtual model fitted a dress made out of a pattern with the same difference in figures. Second, items to evaluate a difference in patterns using 3D clothes modeling software were shoulder line, the distance between shoulder points, armhole line, ease of armscye depth, and overall appearance. Because all the items fall under design lines which make up outer lines of a cloth, it can be said that the Qualoth program is good for representing design, rather than exposing a small difference in patterns.

Recently the car tuning has become a trailblazing and creative culture that expresses the personality of the owner. In this paper, the "Car-Vatar", which is the compound word formed from the words "Car" and "Avatar", has been developed to investigate car tuning on the metaverse engineering platform. The Car-Vatar has been developed as a web-based vehicle dynamic simulation service for providing information about car tuning. That has been focused on investigating diverse vehicular performances, such as acceleration, braking, handling and fuel efficiency, according to the tuning vehicles and tuning parts on the virtual engineering platform. The Car-Vatar platform has provided two major services; one is real-time 3D tuning information system for the dress-up and performance-up tuning parts, the other is diverse vehicle dynamics system for the performance-up tuning parts. To check the validation of the Car-Vatar platform, the comparison between virtual simulation results and driving test results has been discussed on various driving environments.

The purpose of this study is to observe the significance and symbolic meaning of fashion design which is combined with machines, and to develop excellent designs in aesthetic aspects. The method of this study analyzed the related documents and journal, fashion magazines. The results is as follows. The cyborg discourse and virtual human body in virtual world predict the existence of new human. In present times, up-to-date equipments such as wearable computer have begun to be built-in clothing based on technology, and these dress and ornaments influence on human's life gradually in practicality and ability. These equipments are divided as military affairs, medical treatment equipment, leisure, information access and communication, guard, and business assistance. And according to the kind of item, they are divided by headwear, clothing and accessory. The significance of clothing combined with machine is practical viewpoint, economical viewpoint and aesthetic viewpoint. And the symbolic meaning of these fashion combined machine with technology is dis-identity in digital society, dis-borderness between human and machine and the uncertainty of human being. Like this, the clothing which is combined with high-technology shapes its own unique and individual system. But, this must escape from the limit of medium system itself that is technology to become a future clothing for human, suggest new agenda about human and society, and confirm the human being's existence and identity continually.

'스마트'라는 단어가 대중화가 되면서 전자기기 뿐만 아니라 거울에도 스마트가 붙게 되었다. 하지만 스마트 거울에 다양한 기능이 추가되면서 '꾸미는 것을 돕는다'라는 거울 본연의 기능이 부가적인 요소가 되는 경우가 있거나 매장 내에 모델링이 끝난 옷을 보여주지만 집에 있는 자신의 옷을 보는 것이 부족한 경우가 많다. 본 논문에서는 OpenCV를 활용하여 옷을 여러벌 갈아입으면서 코디를 할 때 번거로움을 줄이고자 거울 앞에서 찍으면 프레임과 전경 추출 알고리즘을 사용하여 사용자의 옷을 추출하고 추출된 옷의 정확도를 위해 보정작업을 추가한다. 윤곽선의 노이즈를 줄이기 위해 Morphology 필터링을 사용하고 Clahe 히스토그램 균일화를 통해 옷의 선명도를 높혔다. 추가적으로 가상으로 띄워주는 기능과 옷을 보여줄 때 HSV 모델의 특성을 활용하여 채도나 명도의 변화의 상관없이 색을 추출하여 상의와 하의를 분리하여 상의를 내어입는 기능도 선택할 수 있게 구현 하였다.

The purpose of this study is to review the concept of virtuality and analyze in which way virtuality is expressed in fashion. As for the research methodology, literary research was undertaken to study psychoanalytical and socioeconomic contexts in which virtuality has been formed. In addition, demonstrative studies on styles were undertaken through the analysis of photos in modern fashion magazine. With the explosive diffusion of the Internet since the 1990s, people have created a new identity in cyber space. Indeed, computers have made it possible for human beings to make virtual bodies in any way they want. Through the experiment of creating the figures that they dreamed of in their childhood buy could not embody in their actual life, people are making up for their narcissistic ego of their childhood. With the advent of the cyber society, dreams have been realized in cyber space, which in turn has influenced reality and finally had an effect on fashion. In cyber space, People try to break away from their bodies by combining elements of a different nature from them. They are dying hair and skin, and using holographic fabric for fashion, metallic color and geometric pattern for cosmetics. In pursuit of omnipotent beings, people have depicted models as flying in a weightless state and floating in the water within dress of undefined silhouette, so that they can be shown as transcending the law of nature. Furthermore, a variety of cultures newly appearing as dominant in cyber space have constantly interacted with actual life and formed an collage of heterogeneous cultures in fashion.
