The design of children's hospitals is highly dependent on color schemes. As a space shared together by both adults and children, the design of children's hospitals require color coordination that takes account of the users' characteristics. Visual perception tracking experiment was conducted on the 2 chosen experimental images with a target group made up of adults and children, the following results were found. First, visual attention characteristics of spatial elements' colors were found. The contrast of colors were discovered to effect attention, especially the information desk region showed highest attention. Pillars are subjected to a higher attention relative to other spatial elements, it is suggested when using accent colors to use it only when it is absolutely necessary in partial areas. In contrast, floor patterns were found to be subjected to very low attention relative to other elements. Second, effects of color contrast on visual attention were uncovered. Although color contrast effects attention for both adults and children, children were found to be more effected by color contrast than adults. Especially, children's tendency to rely on color contrast for visual recognition was higher than adults. Since when using only one type on a wide surface children show higher attention on the < vivid > colors than adults, when planning a color coordination for children using < pale > colors instead of < vivid > ones in background for a large surface is seen as a more desired method to increase attention by putting emphasis on the [sharply contrasting] colors.

We present a self-localization method for mobile robots using vertical line features of indoor environment. When a 2D map including feature points and color information is given, a mobile robot moves to the destination, and acquires images from the surroundings having vertical line edges by one camera. From the image, vertical line edges are detected, and pattern vectors meaning averaged color values of the left and right regions of the each line are computed by using the properties of the line and a region growing method. The pattern vectors are matched with the feature points of the map by comparing the color information and the geometrical relationship. From the perspective transformation and rigid transformation of the corresponded points, nonlinear equations are derived. Localization is carried out from solving the equations by using Newton's method. Experimental results show that the proposed method using mono view is simple and applicable to indoor environment.

In this paper, we present a multi-depth generation method using a time-of-flight (ToF) fusion camera system. Multi-view color cameras in the parallel type and ToF depth sensors are used for 3D scene capturing. Although each ToF depth sensor can measure the depth information of the scene in real-time, it has several problems to overcome. Therefore, after we capture low-resolution depth images by ToF depth sensors, we perform a post-processing to solve the problems. Then, the depth information of the depth sensor is warped to color image positions and used as initial disparity values. In addition, the warped depth data is used to generate a depth-discontinuity map for efficient stereo matching. By applying the stereo matching using belief propagation with the depth-discontinuity map and the initial disparity information, we have obtained more accurate and stable multi-view disparity maps in reduced time.

To analyze the design of Christian Dior, 216 pieces of Dior's works were collected and studied from the COLLECTION(Seoul: Dong Ah TV) from 2003 to 2005. The result is as follows. In recent three year period, Christian Dior maintained the feminine image and implemented different additions such as sexy, ethnic, avant-garde and casual image in every season. Also, to reflect a new trend or fashion sense, images of ethnic, retro, hippie or vintage were applied. In using color, different main color(YR, R, Y, BG, RP, B) were chosen every season to pursue variations. For the pattern usage, feminine beauty was presented by numerous applications of flowered pattern. Also the practice of pattern and hue in different rations in every season pursued variations in design.

The purpose of this study was to analyze the meaning and formative features of the black color reflected on the fetish fashion. This study was proceeded mainly by analyzing with references and plates of magazine. The results of the study were as follows ; First, the sexual liberation and revolution have certainly led to a reassessment of sexual deviations, which changed the meaning of fetishism that has been only regarded as sexual perversion, so that it symbolied a new sexual perception and identification. As the result, black in fetish fashion was symbolized a new fetishism\`s definition which refused to distinguish male from female, and also reflected the meaning to express the second sex that wanted to express themselves. Second, the formative features of black color in fetish fashion have appeared tightness and bareness in form, and in material, glancing materials changed by the effect of light, and elasticity materials-leather, rubber, PVC, and laycra. By these features, black fetish fashion has drawn a higher attention on human body than the dress itself as a symbol about the psychology of erotic sensations and sexual images of the self appearing in black color.

In this paper, a detection algorithm for the removal of needle in oriental clinic is presented. First, in the proposed method, the candidate areas of each needle penetrated are selected by using the RGB color information of needle head, and the false candidates are removed by considering their area size. Next, two main edges of the needle are extracted through using the edges of selected candidate areas and their radon transformation. The final verification of penetrated needle is accomplished by using the morphological analysis of these two edge lines. In the experiments, the detection rate of proposed method reaches to 99% for the 36 images containing 294 needles.

This study attempts to detect a shot boundary in films(or dramas) based on the length of a sequence. As films or dramas use scene change effects a lot, the issues regarding the effects are more diverse than those used in surveillance cameras, sports videos, medical care and security. Visual techniques used in films are focused on the human sense of aesthetic therefore, it is difficult to solve the errors in shot boundary detection with the method employed in surveillance cameras. In order to define the errors arisen from the scene change effects between the images and resolve those issues, the mixed algorithm based upon color histogram, edge histogram, and optical flow was implemented. The shot boundary data from this study will be used when analysing the configuration of meaningful shots in sequences in the future.

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 Communication Ocean Meteorological Satellite (COMS) is a geostationary satellite being developed by Korea Aerospace Research Institute. Geostationary Ocean Color Imager (GOCI) is one of the payloads embarked on the COMS satellite. It acquires ocean images around Korea in 8 visible spectral bands with a spatial resolution of about 500 m. The acquired data are used to provide forecasting and now casting of the ocean state. The GOCI operations are controlled by the satellite embedded software, i.e. on-board software. This paper introduces the GOCI payload of the COMS satellite and describes the control software for the GOCI.
