The purpose of this study is to focus on living rooms that are preferred as a place for changing space image to the maximum and to find a method how finishing materials are expressed by selecting space with mix & match of many images. The study methods are as follows. First, understand the expressive trend of space images through the precedent studies and magazines, and examine its relationship with finishing materials. Second, select space images based on the contents understood earlier and extract adjective words that represent each space image through an expert survey. Third, find the cases where space images are expressed based on the extracted words and analyze expression methods of finishing materials. The results of the study are as follows. First, it was confirmed that recent space images are actively expressed through finishing materials. Second, space images selected through data related to the trend were classified as modern+natural, modern+traditional, modern+retro, classic+natural, classic+humor, and futurism+natural and 4 adjective words for each space image were extracted. Third, expressive elements of finishing materials were extracted as 'material'. 'texture', 'color', and 'pattern' through the precedent studies. Fourth, expressive methods of finishing materials for each space image could be suggested by analyzing the examples that show mix & match based on the contents extracted earlier. Lastly, it is expected to find various methods that lead space image into finishing materials by evaluating responses and changes in visual perception of residents according to expression of finishing materials based on this study.

The purpose of this study was to examine the uniform image of Korean herbal cosmetic brands amongst Korean and Chinese consumers. This study would enable us to explore a BI strategy to enhance international competitiveness of Korean herbal cosmetics brands. The results were as follows. The key words of BI pursued by Sulwhasoo were dignified, novel, graceful, soft, gaily, natural, Korean, modern, and international. Korean people felt that the uniform was graceful and soft, which accorded with Sulwhasoo BI, but also it was trite and dingy, indicating a negative and opposing image. On the other hand, Chinese people felt that the uniform was dignified, novel, graceful, natural, modern, and international, indicating that it matched with Sulwhasoo BI. In The History of Whoo, the key words of BI pursued by the brand were precious, soft, gorgeous, gaily, and natural. The Koreans felt that the uniform was intelligent, and decent, but conversely, it was also austere and dingy, indicating a negative image. The Chinese felt that the uniform was common, hard, austere, dingy, and unnatural, indicating an opposing image to BI. Finally, a uniform design was developed to improve on its problems, establish The History of Whoo's brand identity, and its brand image. First of all, 'The Quintessence : noble passion' was set up as a developmental concept. The textiles, clothing, and accessories were designed using the symbolic elements from The History of Whoo as a motif. Uniforms were developed for spring, fall, and summer.

In tangible augmented reality (AR) environments for virtual prototyping, the user interacts with virtual products by manipulating tangible objects with his or her hands, but the user often encounter awkward situations in which his or her hands are occluded by augmented virtual objects, which reduces both immersion and ease of interaction. In this paper, we present how to resolve such hand region occlusion in order to enhance natural interaction and immersive visualization. In the AR environment considered, we use two types (product-type and pointer-type) of tangible objects for tangible user interaction with a virtual product of interest. Holding the tangible objects with his or her hands, the user can create input events by touching specified regions of the product-type tangible object with the pointer-type tangible object. We developed a method for resolving hand region occlusion frequently arising during such user interaction, It first detect hand region in a real image and refines the rendered image of the virtual object by subtracting the hand region from the rendered image, Then, it superimposes the refined image onto the real image to obtain an image in which the occlusion is resolved. Incorporated into tangible AR interaction for virtual prototyping of handheld products such as cellular phones and MP3 players, the method has been found by a preliminary user study that it is not only useful to improve natural interaction and immersive visualization of virtual products, but also helpful for making the users experience the products' shapes and functions better.

The performance of radio frequency (RF) coils, used in MRI units, is determined by the image uniformity and the signal-to-noise ratio (SNR). Birdcage and surface coils are commonly used. A birdcage coil provides a good image uniformity while a surface coil produces a high SNR. In this study, therefore, a staircase coil was designed from a standard version of a birdcage coil, with some structural changes to increase SNR while maintaining image uniformity. In phantom experiments, the improvement of the image to uniformity and the SNR increase of the staircase coil compared with the values for the birdcage coil were about 3.5% and 35%, respectively. In clinical experiment, the SNR increase of the staircase coil, compared with the value for the birdcage coil was about 40% in bone, muscle and blood-vessel tissues. These results show that the performance of the staircase coil was very improved over the standard birdcage coil in terms of SNR, and that image uniformity was maintained. Therefore, the staircase coil designed by this study should be useful in experimental and clinical l.5T MRI systems, and this coil offers an alternative method of quadrature detection.

In this paper, we extend FARGs single mode attribute to multiple attributes for real image application and present a new CBIR using FMARG(Fuzzy Multiple Attribute Relational Graph), which can handle queries involving multiple attributes, not only object label, but also color, texture and spatial relation. In the experiment using the synthetic image database of 1,024 images and the natural image database of 1.026 images built from NETRA database and Corel Draw, the proposed approach shows 6~30% recall increase in the synthetic image database and a good performance, at the displacements and the retrieved number of similar images in the natural image database, compared with the single attribute approach.

For building an urban image, various elements such as symbolic building, ethnic characteristics, historical background, natural environment, and diverse cultural elements can influence on it. Many cities in developed countries are showing their unique urban image reflecting their own culture, history, and aesthetic tastes. Especially color, one of the major design elements, has greater impact than other visual factors to form an urban characteristic. Despite the long history and cultural background, Seoul as a capital city of Korea does not show an unique city image with the perspective of color. Recently, Seoul has been designated as '2010 World Design Capital' and implements various urban design projects. As a leading city of design, Seoul is trying to make its urban identity through the own symbolic environment color. The purpose of this study is to find an environmental color scheme for developing a desirable urban design through several cases of foreign countries. For the purpose, Paris, London, Amsterdam, and Tokyo were selected as case cities. Each of the cities showed their own cultural characteristics and made their unique urban image by appropriate usage of their natural environment, symbolic building, emblem of country, and so on. We need to consider these successful cases to build up the image of Seoul.

The purpose of this study was to evaluate the color image of the natural-dyed silk fabrics. The dye was extracted from pine needle by boiling pine needle with ethanol at $78^{\circ}C$ for 3hours and distilled water at $100^{\circ}C$ for 2hours. The 100% silk fabric was dyed of extract in pH 5 at $90-100^{\circ}C$ for 1 hr. As mordants used were compounds of Al, Sn, Fe, and Cr, color image of pine-needle dyed silk fabrics was classified into 5 factors (pure, gentle, sophisticate, comfortable, pastorale) and the factor pure is most important one of those. Most cheerful image in pure factor was from the fabrics dyed with ethanol extract and then, none and Cr mordanting. Dignified image was from the fabrics dyed with ethanol extract and then, Cu or Fe mordanting. In production, products dyed with ethanol extracts was preferred to those dyed with distilled water extracts. Color image and preference of the silk fabrics dyed with pine needles extracted was affected by extraction solvents and mordants.

The Talbot effect of an elongated circular (EC) grating composed of a line grating and two semicircular gratings with well matched pitches is experimentally presented. As the relative positions between the fixed EC grating and the moving Talbot image of another EC grating or a self Talbot image are one-dimensionally deformed, we can visually observe moire fringes generated by their superposition. Two examples of their applications, that is, the measurement of the wedged angle of a wedged prism and of the fine rotational angle of a mirror are described.cribed.

This study investigated natural aroma fragrance on the fashion image of Galchon, a traditional natural dyeing textile made with immature persimmon from the Jeju area, Korea. Nine fabric pairs consisting of differently colored cotton and silk Galchon with various tones and fabric types were used for subjective evaluation. Thirty five female college students evaluated the specimens using a 7-point scale questionnaire for fashion image-related adjectives. A specimen with three different presentation types that included fabric without fragrance (FO), fabric with citrus fragrance, and fabric with chamaecyparis (FCP) were randomly provided to a subject. As a result, color variables of Galchon were found to be the primary influence on fashion images for both cotton and silk Galchon that showed interaction effects with presentation types. The citrus fragrance increased the feeling of 'Active' while chamaecyparis tended to contribute to a stronger perception of 'Elegance' for cotton Galchon. Finally, these results were used to develop prediction models for fashion images of Galchon that employed color variables and presentation types.

Earthquake disaster frequently happens in Shizuoka Prefecture and it is commonly predicted that a giant earthquake(Tokai Earthquake) could occur in the near future. When a giant earthquake happens, extensive damage of lifelines will be expected. It is considered that the collection of damage information and the establishment of a communication network system are very important in order to restore lifelines quickly. And geographic information system(GIS) might playa very important role to grasp the spatial information of lifeline damage in a natural disaster. The authors' group had a research project to study a lifeline restoration support system with image processing and ad hoc networking in a natural disaster. The objectives of this presentation are to introduce our project and to show some results of our study. The authors finally constructed the GIS for the integration of damage information acquired by image processing and ad hoc networking.
