In this paper, we present a new interpolation method for the color filter away(CFA). In order to capture color images. typical input devices use a single chip CCD imaging sensor with color filter array. As a result, the single chip CCD does not provide sufficient color resolutions since it arranges different color filters sequentially on a single CCD, resulting in aliasing noise and loss of resolution. In order to reconstruct high quality color images, we propose to use the interpolation algorithm using high order B-splines. Experiments show promising results.

Modern Hanbok uses newly different color coordination based on traditional color coordination and symbolic meaning. Thus, this study would investigate the aspects of color coordination and symbolic meaning and present the characteristics of Hanbok as the data of corresponding period in the modern times. In order to investigate recent trend of preferred colors and color coordination of Hanbok, this study focused on the period of 2005~2010. When analyzing colors of Jegori(jacket), Wh, Y, B, YG, P and Gy series are shown in order. For trends for color of Chima(skirt), Pk, R, P, Gy and Bk series are shown in order. When you look into the color coordination of skirt and jacket on whole, color coordination of Pk-Wh represents the highest frequency. Color coordinations of Pk-Y, Pk-B, R-Y, R-G and Pk-G are followed in order. Color coordinations of R-YG, Bk-Wh, O-Y, P-Wh, Pk-YG, Gy-Y, R-Wh series and Gy-Wh are followed in order. When looking into characteristics of overall color coordination of Hanbok, it was shown that there were many opportunities to meet a variety of culture and various colors had emerged depending on individual taste and skin color in the modern times within the framework of basic colors of woman's 'Nokeuihongsang'(Green upper garment and red skirt) R-G, Y series, which are traditionally inherited. In addition, unlike existing traditional color coordination of five elements in the past, P, Gy and Bk series of color appeared in the skirt and Jacket. It could be affected by fashionable drama and films at that time and newly attempted colors ahead of fashion were reflected on the magazine. Therefore, it implied that it naturally gave new awareness of colors to the general public and the width of selection of colors became diverse.

In this paper, we present a color interpolation technique based on artificial neural networks for a single-chip CCD (charge-coupled device) camera with a Bayer color filter array (CFA). Single-chip digital cameras use a color filter array and an interpolation method in order to regenerate high quality color images from sparsely sampled images. We applied 3-layer feedforward neural networks in order to interpolate missing pixel from surrounding pixels. And we compared the proposed method with conventional interpolation methods such as the proposed interpolation algorithm based on neural networks provides a better performance than the conventional interpolation algorithms.

This paper presents a new color correction method for color reproduction on LCD-based monitor by means of high-order multilayer neural networks. LCD monitors have nonlinear characteristics from various displaying system components. To overcome these nonlinearities and produce quality image, we need a nonlinear transformer for color coordinate transformation between the LCD monitor coordinates and the input color stimulus values. A high-order multilayer neural network is effectively trained to learn a mapping to determine the required color value of monitors for producing a given color stimulus. From the experimental results, the proposed method is effective in reproducing the color images.

Color harmony is affected by order of colors or orderly arrangement as well as harmonious colors themselves. In this paper, we show people perceive the degree of harmony differently according to the orderly arrangement of colors. Especially, we use the order of colors in color themes, or color schemes which have been largely used for color selection. We first present the method for harmony calculation of Ou's researches[1][2] and then suggest a method considering minimum color distance of component colors. For a design consisting of multiple colors, we show overall harmony of colors is more important than each harmony of adjacent component colors. By user study, we conclude that the suggested method can enhance the harmony of color theme.

The purpose of this study is to investigate the efficiency of systematic color combination for apparel and textile design. We planned the new color systems, HUE AND TONE COLOR SYSTEM 277 and HUE AND TONE COLOR SYSTEM 253 USED KOREAN TRADITIONAL COLORS. In order to emprove the efficiency, this study aims to explore the development of systematic color combination by computer graphics. With this purpose, this study progressed in the following order and we obtained these results. 1. First, we considered the possibility of the development of the systematic color combination used the new color system, HUE AND TONE COLOR SYSTEM 277. We considered the possibility of the development of the systematic color combination by graphic computer SDS-480. Through the experimental regulation of the RGB (Red, Green, Blue) and HLS (Hue, Lightness, Saturation) we obtained an approximation of the colors of the HUE AND TONE COLOR SYSTEM 277 on the CRT display of SDS-480. 2. We planned the new color system, HUE AND TONE COLOR SYSTEM 253 USED KOREAN TRADITIONAL COLORS for systematic color combination. 3. In a practical application, we tried five principal types of color combination in apparel and textile design, monochromatic combination, tone on tone combination, moderate combination, tonal combination, and contrast combination. 4. Furthermore, we applied the systematic color combination for the textile patterns by tone on tone combination. By using the systematic color combination for apparel and textile design, we realized the efficiency and utility of the systematic color combination.

In this paper, we focus on digital watermarking for color images. At first, in order to embed the watermark signal in color image, we converted RGB color space to YCbCr color space which is a world-wide digital component video standard. In addition, we adopted the acceptable degree of color difference in order to keep the invisibility.

The purpose of this research was to conduct a comparison analysis of color in the characteristics and image of Korea/China/Japan airline uniforms. Research subjects for this research included 19 Korean, Chinese and Japanese airlines servicing the Incheon International Airport in South Korea. The analysis methods are based on the Munsell Color Order System and PCCS (Practical Color Coordinate System) tone classification in order to examine the color characteristics. For the color image analysis, the present research performed a positioning on Shigenobu Kobayashi's color images scale with adjectives in order to compare the resulting differences. As a result of the analysis, this research discovered the following; First, achromatic colors were found to be used most frequently in flight attendant uniforms of Korea/China/Japan. In Korean flight attendant uniforms, YR/Y, GY and B/PB/P; in Chinese, R/PB, RP, YR/Y/GY and BG/P; in Japanese, RP, R/P/PB and Y/BG were found in order. As for the main uniform colors, Korean flight attendant uniforms were found to be in the colors YR, and R/GY/B/P; Chinese flight attendant uniforms, R, PB, and P/B; and Japanese flight attendant uniforms, R, BG, B, RP and N. Second, Korean flight attendant uniforms used W and It most frequently; China flight attendant uniforms, W; and Japanese flight attendant uniforms, W and v. Regarding the main colors, Korean flight atteddant uniforms used lt/g and v/p; Chinese flight attendant uniforms, v, dp and s/d/dkg; and Japanese flight attendant uniforms, v/dkg and Bk. Third, after positioning each country's uniform color combination bars on the Kobayashi image scale, Korean flight attendant uniforms showed classic images along with casual/pretty/elegant/chic images; Chinese flight attendant uniforms displayed, casual images as well as, dynamic/gorgeous/chic/cool casual/dandy images; and finally, Japanese flight attendant uniforms converyed dandy images along with casual/gorgeous images. This research findings indicate that Korea/China/Japan airlines' flight attendant uniforms seek for differentiated image establishment by reflecting their own CIs and unique national cultures in the uniform color marketing.

The subjective experience would degrade the current artificial artistic aesthetic analysis. Since Qiong kiln ceramics have a long history and occupy a very important position in ceramic arts, we employed computer-aided technologies to quickly automatically accurately and quantitatively process a large number of Qiong kiln ceramic images and generate the detailed statistical data. Because the color features are simple and significant visual characteristics, the color features of Qiong kiln ceramics are analyzed for the quantitative aesthetics. The Qiong kiln ceramic images are segmented with GrabCut algorithm. Three moments (1st-order, 2nd-order, and 3rd-order) are calculated in two typical color spaces, namely RGB and HSV. The discrimination powers of the color features are analyzed according to various dynasties (Tang Dynasty, Five Dynasties, Song Dynasty) and various utensils (Pot, kettle, bowl), which are helpful to the selection of the discriminant color features among various dynasties and utensils. This paper is helpful to promoting the quantitative aesthetic research of Qiong kiln ceramics and is also conducive to the research on the aesthetics of other ceramics.
