The purpose of this study is to analyze the aesthetic factors in color combinations of house exteriors in hillside villages, Busan. The so-called 'Hillside renaissance' is a representative urban regeneration project in Busan. The towns in hillside area in Busan have developed colorful sceneries. But all the colorful sceneries are not the same. Each town has own color characters and different aesthetic color effects. This study is to determine the unique aesthetic components in color combination of Gamcheon and Daecheong. This study is based on the traditional color harmony theories. The analysis focuses, inter alia, on Moon-Spencer's 'Aesthetic Measure'. A house exterior color has relations with two neighboring colors in array. And those three colors with next two houses have again each three hue, value and chroma relations. This analysis is first to determine whether each sample color combination is harmonized, and if harmonized, next step to list which aesthetic factor is dominantly contributing to color harmony. And at last, to study the subcategorized sectors of each color components of the hue, value and chroma.

A robust and efficient text extraction is very important for an accuracy of Optical Character Recognition (OCR) systems. Natural scene images with degradations such as uneven illumination, perspective distortion, complex background and multi color text give many challenges to computer vision task, especially in text extraction. In this paper, we propose a method for extraction of the text in signboard images based on a combination of mean shift algorithm and weighting scheme of hue and saturation in HSI color space for clustering algorithm. The number of clusters is determined automatically by mean shift-based density estimation, in which local clusters are estimated by repeatedly searching for higher density points in feature vector space. Weighting scheme of hue and saturation is used for formulation a new distance measure in cylindrical coordinate for text extraction. The obtained experimental results through various natural scene images are presented to demonstrate the effectiveness of our approach.

The Heian Period(794-1192) was the period when luxury and elegance flourished. Gorgeous colors were adopted for the costumes and an el-egant assortment of colors prevailed. Representatiove of such costumes is kasane-no-irome. The world Kasane-no-irome originally came from two colors on both sides of one of the japanese kimonos called Uchiki. In later times it turned to indicate the combination ef-fect of colors of several Uchiki's worn in layers one over the other. This paper describes in de-tail the kasane-no-irome in both meanings. In so doing I distinguish two different kinds of kasane-no-irome using a Chinese character for the formed and for the latter though both are pronounced Kasane in the Japanese language. Part one of this paper which concerns the color combinations of presents typical 148 samples through reproduced dyeing clothes by Matumoto. Part two describes the color com-bination of which was so called Junihitoe. It presents typical 41 samples from reproduced dyeing clothes by Matumoto. The purpose of this study was to investigate the characteristics of color distribution and the structure of color combination in Kasane-no-irome. Therefore we obtained the following results in Kasane-no-irome. 1. The color combination of Kasane-no-irome came from the natural color harmony there-fore the names of kasane-no-irome which adopt the names of flowers and leaves of the foure seasons. Accordingly the seasons for wearing them are fixed. 2. In the hue the most frequent appearance was green. And in the tone the most frequent apperance was moderate. 3. In the color combination the most fre-quent type were monochromatic combination and contrast combination.

This study was aimed to analyze color characteristics of silk fabrics dyed with a variety of commercial natural dyes focusing on hue/tone system. Using eleven different natural dyes, single and sequential dyeing were performed under a variety of conditions of dye bath concentration, mordanting, and dyeing sequences. Color characteristics of dyed silk fabrics were investigated by Munsell's color notation of H V/C and PCCS (Practical Color Coordination System) tones. As results, most of yellowish natural dyes as principal shades in natural dyeing showed Y or YR for hue families while d, ltg, and g for tone, which agrees with colors frequently used in comtemporary apparel industries. As for single dyeing, some hues like R, RP, G, GY, and BG were found to have their own tones owing to the used natural dyes. For varying hues in natural dyeing, sequential dyeing is useful in that GY, G, and BG rarely appeared in single dyeing were frequently shown in sequential dyeing by combination of some dyes. In the other hands, mordanting may be employed for tone variation in that aluminum seemed to contribute to light and dull tones, copper to dull, and ferrum to garyish and dark ones. These results can be helpful to design colors for fashion fields by natural dyeing.

The evaluation of package temperature for fresh preservation of cucumber was investigated. The fresh cucumber is available in markets of Korea during whole seasons, for the help of farmer, distributor and consumer. Cucumbers were stored within cardboard boxes packaging covered with low density polyethylene (LDPE) at different temperatures (5, 10, 15 and 20℃). Changes in weight loss, hue angle, firmness, moisture content and general appearance (shape of cucumber) were investigated during storage of cucumbers. General appearance index with non-packaging decreased more than with LDPE film packaging at 5℃ and 10℃. During storage of cucumbers, general appearance index as freshness showed packaging effect at low temperature than room temperature. In the fresh weight loss, the packaged cucumbers were less reduced than that of the non-packaging ones. At color change, Hue angle of cucumber stored within low temperature with film packaging decreased gradually during storage. However remarkable change in hue angle were observed in cucumber within LDPE film packaging treatments of 15℃ and 20℃ storage. The effect of hue angle with packaging appears differently depending on the storage temperature conditions. The firmness and moisture content of cucumber flesh were not affected by packaging and storage temperature. In this experiment, cucumbers packaged with LDPE film at 5℃ and 10℃ were the most desirable for extending the quality. These results suggest that packaging of low temperature treatments in combination could be effective in prolonging the shelf life of cucumber.

Advertising signboards are designed for the visibility to affects recall and recognition of costumers. It is well know that the visibility from images is created by the value difference among colors. The research defines whether the background color combination of outdoor signboards is configured to maximize visibility, by a series of color value variation in complex commercial facilities. The subject of study is to examine how the visibility is made by the color combination since visibility cannot be obtained independently. Two steps of analysis were performed to confirm that the color composition of signboards was based on the color value difference. The first is to analyze that the entire colors of signboards are clearly categorized as different value groups. All components of colors, hue, value and chroma had been analyzed by color aesthetic measures to prove that the value variation has the only regularity and the principle of composition. The second step is a further verification with an ample amount of samples to determine whether series of signboards create a value altering pattern. The data for analysis is gained by colorimetric survey and the color data are used for exponentializing the degree of combining, which shows selective affinity between each pair colors.

The objectives of this study were to analyze the color characteristics of Saikdong by the standardized color system and to applicate it's color characteristics to fashion design. 25 traditional costumes made with Saikdong were selected from four museums in Seoul. The colors were measured using CE 310 and analyzed by Munsell HV/C. The results were shown as follows; 1. The frequently used hues in Saikdong are warm colors such as red, orange, yellow. Except purplish blue, cool colors show low usage ratio. 2. The tones of medium lightness and saturation are most frequent in Saikdong colors. 3. The characteristics of color combination are the contrast of hue and the similarity in tones. This makes the saikdong splendid and harmonious. 4. Based on this anaylized characteristics of Saikdong color combination, fashion designs were developed by computer simulations.

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 paper presents a content-based image retrieval (CBIR) method using the combination of color and texture features. As a color feature, a color autocorrelogram is chosen which is extracted from the hue and saturation components of a color image. As a texture feature, BDIP(block difference of inverse probabilities) and BVLC(block variation of local correlation coefficients) are chosen which are extracted from the value component. When the features are extracted, the color autocorrelogram and the BVLC are simplified in consideration of their calculation complexity. After the feature extraction, vector components of these features are efficiently quantized in consideration of their storage space. Experiments for Corel and VisTex DBs show that the proposed retrieval method yields 9.5% maximum precision gain over the method using only the color autucorrelogram and 4.0% over the BDIP-BVLC. Also, the proposed method yields 12.6%, 14.6%, and 27.9% maximum precision gains over the methods using wavelet moments, CSD, and color histogram, respectively.

Color is basically composed of hue, saturation and value. Many objects are made up with color. When people see color, they feel different emotion because of different combination of hue, saturation and value of different colors. Thus, people feel different feeling about the taste of food depending on its color. Thus, by analyzing what color makes people feel tasty about food, we can make food to look more delicious. When people take pictures of food, theyusually do not consider this into account. However if we apply this technology into taking pictures of food, we can make the food look more delicious. This technology can be applied when people want to upload pictures of food in blog, homepage and twitter and so on. In this paper, we analyze the feelings of color of people and then choose the best color combination to present food. After that we change the original image into the new one based on the analysis of color. This way, we can reflect each user's preference.
