  • A Study on the color comparison of Korean Saek-dong and Italian futurist fashion It is generally recognized that the color scheme and its characteristics as a product of living culture are strongly reflected in clothing. This study concentrates on the color comparison of Korean Saek-dong which has been used in traditional Korean clothing and Italian futurist fashion which showed dynamic characteristics and brilliant colors. The purpose of this study is to investigate the external format, emotions, functions and meanings of the colors in Korean Saek-dong and Futurist fashion, and to find similarities and differences between them. The results of the study are as follows. The similarities between them are harmony of vivid colors like a rainbow, no-use of black color and expression of rhythm through repeated geometrical shapes. They have been used as festive costumes and have implied meaning of happiness and pleasure. The differences, in the external formats, are as follows. Korean Saek-dong has striped patterns including the color white, and has regular distances among the stripes. But, Futurist fashion includes luminous or fluorescent colors and metallic colors. In addition, it has repeated motifs of geometrical shapes and geometrically divided areas. While Saek-dong expresses Sangsaeng through the conceptual use of color, Futurist fashion shows simultaneity, speed and dynamics through spiritual functions of crossing and inter-penetration. In emotional aspect, Saek-dong expresses pleasure of children's mind and Futurist fashion expresses pleasure of city. In functional aspect, Saek-dons expresses a concept of ceremonial beauty, which is spiritual and symbolizes good auspices, holiness and sorcery. So it is used for ceremonial costume. But, Futurist fashion reflects the harmony of colors created from modem and urban images and shows the willingness and emotion of solving futuristic avant-garde, modernity, dynamics, transformation and bellicosity. So it is used for daywear. While Saek-dong represents succession of tradition, Futurist fashion represents resistance of tradition in cultural aspects.

  • 기존의 영역기반의 영상정합이나 에피폴라 기하 혹은 고도값 제한 등을 통해 정합의 탐색영역을 줄임으로 영상정합의 효율성을 높이는 방법들은 비슷한 형태의 고층 건물이 밀집되어 있는 대규모 도심지와 같은 경우 오정합의 가능성이 크며 정합에 소요되는 시간도 여전히 오래 걸리는 단점을 갖고 있다. 이러한 단점을 보완하기 위하여 건물 인식을 통한 영상정합법에 대하여 연구를 수행하고자 한다. 본 논문에서는 새로운 영상정합기법의 기초연구로서 컬러영상으로부터 경계정보와 색상 정보를 활용하여 동일 건물 인식에 관하여 실험을 수행하였다. 경계정보와 색상정보를 활용하기 위하여 각각 보완된 Hausdorff 거리개념과 보완된 컬러 인덱싱 기법을 적용하였다. 각각의 정보를 단독으로 활용한 경우 동일건물의 인식률이 경계정보의 경우 46.5%, 색상정보의 경우 7.1%로 매우 낮았으나, 두 가지 정보를 조합하여 인식을 실시한 결과 78.5%로 인식률이 높아지는 것을 확인할 수 있었다.

  • We propose a visible light communication system in which the color and brightness are controllable. Pulse width modulation and variable pulse position modulation (VPPM) schemes are used to control the color and brightness, respectively. A digital algorithm to decode VPPM signals is suggested and implemented. A seamless transmission is observed in a testbed experiment under various environmental conditions. The proposed scheme can be applied to emotional-lighting-based wireless optical communication.

  • An important issue in the field of face recognitions and man-machine interfaces is an automatic detection of faces in visual scenes. it should be computationally fast enough to allow an online detection. In this paper we describe our ongoing work on face detection that models the face appearance by edge orientation and color distribution. We show that edge orientation is a powerful feature to describe objects like faces. We present a method for face region detection using edge orientation and a method for face feature detection using local color information. We demonstrate the capability of our detection method on an image database of 1877 images taken from more than 700 people. The variations in head size, lighting and background are considerable, and all images are taken using low-end cameras. Experimental results show that the proposed scheme achieves 94% detection rate with a resonable amount of computation time.

  • In the design of any picture book, graphic artists employ the use of color, typeface and illustration to produce attractive book covers. This study is an analysis of selected book covers in the 'Africana Children's Book Awards' (Young Readers category) between 2009 and 2014. The book covers are mainly illustrations originally done in media such as acrylics and oil paintings on canvas. In the article, the author analyses the front covers in terms of hue, Saturation and brightness using a colour map. This work also discusses why certain colours have been used in the design of the covers thus; providing information on color scheme trends for picture books in the Children's Africana Awards Category.

  • In this paper, we propose a new view synthesis technique for coding of multi-view color and depth data in arbitrary camera arrangements. We treat each camera position as a 3-D point in world coordinates and build clusters of those vertices. Color and depth data within a cluster are gathered into one camera position using a hierarchical representation based on the concept of layered depth image (LDI). Since one camera can cover only a limited viewing range, we set multiple reference cameras so that multiple LDIs are generated to cover the whole viewing range. Therefore, we can enhance the visual quality of the reconstructed views from multiple LDIs comparing with that from a single LDI. From experimental results, the proposed scheme shows better coding performance under arbitrary camera configurations in terms of PSNR and subjective visual quality.

  • The esthetic demands are growing in treatment of primary maxillary incisors as well as permanent ones. There is something dissatisfying about in the keen eyes of the pediatric dentists on their esthetic results of efforts because current tooth color system is created for the purpose of the application to the permanent incisors. In this study using the scientific color measurement device, I would like to introduce a color scheme for the primary maxillary incisors and suggest clinical tips for the better results of resin composite restorations.

  • Intelligent Space defines an environment where many intelligent devices, such as computers and sensors, are distributed. As a result of the cooperation between smart devices, intelligence emerges from the environment. In such scheme, a crucial task is to obtain the global location of every device in order to of for the useful services. Some tracking systems often prepare the models of the objects in advance. It is difficult to adopt this model-based solution as the tracking system when many kinds of objects exist. In this paper the location is achieved with no prior model, using color properties as information source. Feature vectors of multiple objects using color histogram and tracking method are described. The proposed method is applied to the intelligent environment and its performance is verified by the experiments.

  • 본 논문에서는 안전한 웹 맵 매쉬업 서비스 구현을 위한 위성영상의 원근거리 기반의 위성영상 워터마킹 기법을 제안한다. 제안한 방법에서는 위성 영상의 위치 정보와 사용자 정보를 위성 영상의 원근거리에 따라 에지 및 색상 히스토그램 분포에 은닉한다. 따라서 사용자 요구에 의해 서비스되는 임의 해상도의 위성영상들에 대해 해당 해상도의 영상 특성에 적합한 워터마킹 기법을 수행하여 해당위성 영상을 악의적으로 수정하여 불법 유통한 유통자를 추적하고, 사용자의 사생활 보호 할 수 있다. 실험 결과 제안한 기법의 비가시성이 우수함을 확인하고, 회전, 이동 등의 기하학적 공격에도 삽입된 워터마크가 강인함을 확인한다.
