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.

The traditional area-based matching or efficient matching methods using epipolar geometry and height restriction of stereo images, which have a confined search space for image matching, have still some disadvantages such as mismatching and timeconsuming, especially in the dense metropolitan city that very high and similar buildings exist. To solve these problems, a new image matching method through building recognition has been presented. This paper described building recognition in color stereo images using edge and color information as a elementary study of new matching scheme. We introduce the modified Hausdorff distance for using edge information, and the modified color indexing with 3-D RGB histogram for using color information. Color information or edge information alone is not enough to find conjugate building pairs. For edge information only, building recognition rate shows 46.5%, for color information only, 7.1%. However, building recognition rate distinctly increase 78.5% when both information are combined.

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.

In this paper, the novel and simple scheme of producing full color image bye use of binary phase holograms and three lasers of red (632.8 nm), green (543.5 nm), and blue (488 nm) is presented. Three holograms are designed and fabricated separately so that different laser beams can pass through the different holograms. The diffracted beams from the holograms constitute the wanted color image at the focal plane. The theory and experimental results of the system are also presented.

This paper presents a watermarking scheme based on the perspective distance for the secure mash-up service. The proposed scheme embeds the watermark of the location information of satellite image and the user information using edge color histogram, which is dissimilar to general digital image. Therefore, this scheme can trace the illegal distributor and can protect private information of user through the watermarking scheme that is adaptive to satellite image. Experimental results verified that our scheme has the invisibility and also the robustness against geometric attacks of rotation and translation.
