  • Perceiving the depth of space in the spatial organization of architecture is perceiving spaces as well three dimensions as the fourth dimensions -perceive the time-. Physical depth in architectural space differs from perceptional depth in aspects of not only dimension but also perceptional effects. In this study, the perceptional depth is defined as visual depth and physical depth is depth of space. These purposes of this study are classifying the perceptional effects of visual depth -visual access, sense of variety, dynamic and cubic effect... - and the methods of spatial composition which causes visual depth in architectural space.

  • DIBR(depth image-based rendering) 기법은 한 장의 칼라 영상과 그에 대응하는 깊이맵을 이용하여 수신측에서 가상의 좌우 영상을 생성하여 시청자에게 깊이감을 제공해주는 방법이다. 이 때 생성되는 좌우 영상의 화질과 깊이감은 좌우 영상의 시점에 해당하는 가상 카메라의 간격에 영향을 받게 된다. 본 논문에서는 가상 카메라의 간격 조절을 통해 양질의 깊이감을 제공하는 기법을 제안한다. 영상의 기하 분석에 따르면 스테레오스코픽 영상의 변이가 증가할수록 영상의 왜곡이 줄어들어 깊이감이 좋아지게 되나, 이 경우에는 그에 따른 영상의 열화가 고려되지 않았다. 실험결과에 따르면 영상열화나 시역형성의 제한 등으로 인해 변이의 증가폭에 제한이 있음을 알 수 있다. 변이 증가폭을 늘리기 위해서는 영상의 열화 현상을 줄여야 하므로 깊이맵의 전처리 과정을 추가하였다. 제안하는 방법은 시청자의 요구에 따라 카메라의 위치와 시점을 추가적으로 조절할 수 있게 하는 양방향 서비스를 추가로 제공하므로 3차원 TV 뿐만 아니라, DMB와 같은 이동형 방송 시스템에도 적용이 가능하다.

  • With the development and spread of 3D display, users can easily experience an augmented reality with 3D features. Therefore, the demand for content of an augmented reality is exponentially growing in various fields. A traditional augmented reality environment was generally created by CG(Computer Graphics) modelling production tools. However, this method takes too much time and efforts to create an augmented environment. To create an augmented environment similar to the real world, everything in the real world should be measured, gone through modeling, and located in an augmented environment. But the time and efforts spent in the creation don't produce the same environment as the real world, making it hard for users to feel the sense of reality. In this study, multi-scale 3D panorama content augmented system is suggested by using a depth-map. By finding matching features from images to add 3D features to an augmented environment, a depth-map is derived and embodied as panorama, producing high-quality augmented content system with a sense of reality. With this study, limits of 2D panorama technologies will be overcome and a sense of reality and immersion will be provided to users with a natural navigation.

  • 오늘날의 디지털영상 제작기술의 발전과 더불어 3D 이미징 기술은 첨단 TV와 컴퓨터에 응용되고 있으며 3D 입체 영상 제작 기술에 대한 연구, 개발이 활발히 진행되고 있다. 2009년 개봉한 제임스캐머런(James Cameron)감독의 3D입체영화 '아바타' 흥행 이후 3D 입체영상에 대한 관심이 대두 되고 있는 상황에서 본 연구는 최근 대두되고 있는 입체영상제작에 있어서 후반제작 공정상 색 보정이 입체의 깊이감에 미치는 영향을 실험하였다. 기존 영상제작 후반작업에서의 색 보정과정을 3D입체영상 제작과정에 적용하여, 입체감 변화에 대한 데이터를 측정하고 이를 통하여 3D 입체영상 제작에 있어서 효과적인 영상처리프로세스에 대한 정보를 제공하는 것이 연구의 목적이다. 입체영상에서 색과 명암대비가 입체의 깊이감을 인지하는데 영향을 줄 수 있다는 가정을 전제로 색 보정 실험을 하였다. 입체감, 공간감, 깊이감의 변화에 대한 피 실험자 반응을 종합하여 입체감이 상승하는 결과를 확인 할 수 있었다. 본 실험을 통하여 도출된 결과를 적용하여 15분 분량의 입체홍보영화를 제작 하였으며, 후반제작과 정상에서 색 보정 작업 결과가 입체를 인지하는 깊이감에 영향을 미치는 것으로 확인됐다. 본 연구의 실험은 평행리그와 직교리그를 통하여 촬영된 좌측영상과 우측영상의 영상이미지를 실험 데이터로 사용하였으며 편집과정에서 컨버전스와 입체감을 수정한 후에 후반제작에서 색 보정 작업을 통하여 명암대비를 높였다. 그 결과 영상의 공간감과 깊이감, 그리고 돌출감이 증가한 영상을 제작 할 수 있었다.

  • The term fashion sense is used in everyday conversations by consumers to refer to the ability of people who dress well in attractive ways or to refer to the competencies or expertise of fashion professionals. Despite the frequent use of the term, its concept has rarely been explored systematically. In this study, we performed in-depth interviews with 14 fashion experts to clarify the concept of fashion sense. The core elements of fashion sense were explored based on the interview results. As a result, twelve core elements were identified that included visual ability, aesthetic experience, aesthetic recognition ability, intuition, self-consciousness, self-efficacy, fashion experience, involvement in fashion, creativity, innate sense, environmental support, and development due to education. In addition to these twelve core elements, 42 supplementary elements were identified. This study is to help initiate an academic discussion of the concept of fashion sense as a competency that fashion experts should develop. The findings of this study can provide practical and educational implications for the fashion industry and academia.

  • Bad weather conditions such as haze lead to a significant lack of visibility in images, which can affect the functioning and reliability of image processing systems. Accordingly, various single-image dehazing (SID) methods have recently been proposed. Existing SID methods have introduced effective visibility improvement algorithms, but they do not reflect the image's perspective, and thus have limitations that distort the sky area and nearby objects. This study proposes a new SID method that reflects the sense of space by defining the correlation between image brightness and haze. The proposed method defines the haze intensity by calculating the airlight brightness deviation and sets the weight factor of the depth map by classifying images based on the defined haze intensity into images with a large sense of space, images with high intensity, and general images. Consequently, it emphasizes the contrast of nearby images where haze is present and naturally smooths the sky region to preserve the image's perspective.

  • The purpose of this study is to examine the residents' life style affected by community-oriented behavior, and to assess the implication of changes in communities and in the participants' sense of community resulted from the Community Currency Movement in Korea. 4 Community Currency organizations were selected for this study and some methodologies such as field research, survey of actual conditions and depth interview research were used, By using of this methodology. We can analyze the characteristics of Community Currency Movement in Korea and the degree of participants' sense of community. As a result of this study, it was found that the residents recognized 'new' community and felt 'a sense of belonging' by exchanging the community currency. They have also expanded 'a sense of responsibility' for the community through the exchange of this currency. Along with this change of attitude, participants have made a new community norms and they have been more or less controled by the norm. Moreover, the emotional satisfaction and the needs for improving self-esteem have been realized within the community, and the intimacy as well as solidarity have been built up and enhanced. In conclusion, the Community Currency Movement gives a significant implication to the communities that seek to solve the community problems of the contemporary society through the communal effort by the residents themselves. Furthermore, in terms of community welfare, this process will be of an immense help in reinforcing self-help ability of the residents effectively.

  • In the recent years, significant advances have been made in the development of small form-factor, low power, and low cost 3D-sensing devices based on depth-imaging technologies with real-time performance. This has led to the advent of devices and machines that are able to sense and understand the world, navigate in the environment, and interact naturally with their human users. Human-computer interactions based on touch sensing and speech recognition have already become mainstream, and the rapid developments in 3D sensing is paving the path towards the next level of machine intelligence and interactions. This paper discusses the recent developments in real-time 3D sensing technologies and their emerging system application.

  • This study was conducted to enhance the cubic effect by representing an image with a sense of three-dimensional (3D) depth, using chromostereopsis, among the characteristics of human visual perception. An algorithm that enhances the cubic effect, based on the theory that the cubic effect of the chromostereoptic effect and the chromostereoptic reversal effect depends on the lightness of the background, classifies the layers of the 3D image input into the foreground, middle, and background layers according to the depth of the image input. It suits the characteristics of human visual perception because it controls the color factor that was adaptively detected through experiments on each layer; and it can achieve an enhanced cubic effect that is suitable for the characteristics of the image input.
