In this paper, we look photographes of costumes and composed them as image files by extracting only costume part of the photograph excluding the background part. And we calculated representative color value to implement smart costume coordination program using complementary colors corresponding to representative color values in the costume area. And then, We have solved the problem of over-segmentation caused by extracting the costumes area by applying an anisotropic diffusion algorithm that can remove the noise of the image and flatten the gradient. In order to satisfy users' various needs, we plan to add not only complementary colors coordination but also more various color scheme.

본 논문에서는 점묘화를 생성하기 위한 회화적 렌더링 기법을 제안한다. 신인상파(Neo-Impressionist) 화가 쇠라는 캔버스위의 독립 색채들은 망막위에서 재조직된다는 이론을 바탕으로 점묘화를 제안한다. 이는 색의 병치혼합과 보색대비를 이용해 빛의 가산혼합이 회화작품에 적용될 수 있도록 하기위해 브러시 스트로크로 작은 점을 이용한다. 이러한 점묘화를 표현하기위해서 쇠라의 작품과 동시대의 색이론 분석을 통해 색의 분할과 병치혼합의 이론적 배경을 알아보고 이를 통해 점묘 스트로크의 색상, 모양, 방향등을 결정할 수 있는 알고리즘을 소개한다. 먼저 신인상파의 팔레트 분석을 통해 칼라모델을 설계한다. 그리고 입력영상을 영상분할 기법을 이용해 공간적 구도를 잡고 각 분할 영역의 관계를 고려해 색상을 할당한다. 각 할당된 색은 보색과 함께 정의된다. 각 분할영역은 해당영역에서 표현될 수 있는 색상의 작은 점묘 브러시 스트로크로 렌더링이 된다. 이때 입력영상의 밝기정보를 유지할 수 있도록 점묘 스트로크는 색상이 결정된다. 점묘 스트로크의 방향은 입력영상의 에지방향을 따르도록 보간법을 이용해 계산한다.

Mobile display panel is small so that users are often difficult to perceive images clearly. About image we perceive much through colors and therefore we propose color fitting approach for clear perception even on the small and low quality LCD panels. Various color modifications have been studied and used in commercial software packages. For mobile usage, our approach instantly enhances color images by modifying colors in a way to contrast differences of them. The method includes tone enhancements (which contrast dark and bright sides) and color enhancements (which reduce saturation for pure colorants). Based on color theory, our method also modifies color values towards specified complementary and preference colors. We term this color fitting. This approach enables displaying photos, multimedia messages, videos and digital media broadcasting (DMB) for better perception in real-time on mobile devices. Index Terms.) color fitting, visualization on small display, mobile graphics, visual perception.

In the modern 21st century society, the personal image is considered to be very important. As a result, the importance of presenting one's personal image through personal color in fashion and beauty related fields are increasing, and is the most realistic and practical field of color. When the color of the wardrobe and the skin color are in disharmony, that disharmony becomes the source of the lines and wrinkles that appear on one's face, resulting in shades. The boundary that is created when the color of the wardrobe and the skin color are in disharmony, it works negatively on one's image. When color arrangements are close or similar (in harmony) or are in complementary color arrangements or in strong contrasting state (contrasting harmony), it is generally believed to be beautifully harmonious. Personal color assessment is finding colors, through systematic and scientific methods, that improve the personal image by reaching harmony with skin colors that each and every individual are uniquely born with. In this study, one was able to learn the improved visual effects of the face image through creating harmony with the wardrobe and color shade make up and complementary colors that were selected based on personal colors. The base make up, through using the contrasting effects of the complementary colors which represents the supplementing, correcting, and complementing of the face image by contrasting with complementary colors, brings positive changes through correcting the base skin color. It is believed that this study finds its importance in that the improved image that is created by the overall harmony of the wardrobe and body can be used as valuable data in marketing and new product development efforts in the related industries.

The significant role of colors in fashion design is not enough to emphasize in terms of one of the important design elements and its influences on the behaviors of the people. The purpose of this research is to examine the traditional Chinese colors and its ways of color combinations to appreciate the Chinese culture and its people. The Chinese traditional costume of Ching Dynasty were investigated through historic records, historic nobles, costume accessories and so on. The results of the study were summarized as follows： (1) The Blue was the most favoured color for clothing among men and women during Ching dynasty and various blues in terms of hue, value and intensities were used. (2) The bright Yellow which had been a symbol of Emperor were prohibited being used among people. Though, the late period of Dynasty, the regulation became not to strict and various shades of yellow families were adapted among People. (3) The Red which had been preferred during Ming Dynasty were constantly favoured for the formal wears of auspicious events such as weddings. (4) Dark color groups were loved for the clothing which were used as a ground colors against the flamboyant patterns revealing strong visual effects through value contrast or primary color combinations. (5) The White had a symbol of mourning and there were some intentions to adopt pale color groups such as mint, jade, gray, moon whit,. silver white to make up for white. (6) Contrast color combinations were one of the basic ways of color combination in Chinese traditional costume. Therefore Chinese color combinations has a strong visual effect and easy to draw attention of people by the contrast of the hue, value or intensity of color. (7) Multi-color combinations were another characteristics of Chinese costume in the formal wears which bears many surface designs. The surface decorated with full of motifs, were appreciated by the people expressing their longings and hopes through the auspicious meanings of patterns and striking visual effects of color combinations.

This study analyzed the differences of tableware and garnish decoration in color and material by conducting a content analysis of 1,357 pictures from food-styling magazines and a survey of 84 restaurants in Seoul. The data used for the study were collected from Cookand and Best Home Magazine and the survey results of the restaurants. Results of the study were as follows: First, both food coordinators and upscale restaurants preferred porcelain while low-priced restaurants tended to use plastic as materials. Second, the preferred color of tableware was white as it is believed to represent the image of neatness and purity. Therefore, food coordinators prepared food in magazines for food-styling and upscale restaurants using white porcelain tableware, and low-priced restaurants also did using white plastic tableware. Finally, the preferred color of garnish decoration was green. Most professional food coordinators tended to use red and green colors to emphasize the combination of complement colors, and some expensive restaurants used five garnish decoration colors.

This study is for the use of color recommendation system for the color combination of mobile application. For this study, color combination methods of a material design color system that recommends harmonized colors automatically and of a mobile web application were applied to a mobile application design and a color combination experiment was carried out. Then for a survey on the experiment using the two methods, color combinations, selected colors and satisfaction with outputs were investigated on a 7-point Likert scale. And color combination characteristics of outputs were compared. It was found that the material design color palette made it easy to select colors by systematizing the regular coloring stages of fixed colors automatically, but there were differences in color compositions and color scopes of dominant color, assort color and accent colors, which are three-color combinations of mobile web application and accent color selection function was required for each design, since only primary colors and secondary colors could be selected. Moreover, chromatic colors were used a lot in the material system because of the fixed color scopes and color combination scopes and images of color combination outcomes varied depending on the color combination scopes, even when tones with a big contrast or complementary colors were selected. The role of color composition was important according to the color combination scopes.
