The process of selecting a small number of representative colors from an image of higher color resolution is called color image quantization. In a color quantization process, it is vet important to determine what colors should be preserve and the others not. In our study, by the idea of an image can be divided into interesting area and uninteresting area, we propose a color quantization method that preserves more colors in the interesting area of an image. We evaluated correctness of extracting interesting area and compared the quality of our method with the others.

Surface color is the most important quality factor for the grade evaluation of cherry tomato. Color is one of the representative indicators for the maturity which is closely related to the internal quality of cherry tomato, such as firmness, sugar content, and acidity. This study was carried out to investigate the relationship between surface color and internal quality of cherry tomatoes harvested from both hydroponic and soil culture at different ripening stages. To calculate the color values of cherry tomatoes an automatic color imaging system was constructed. A specially designed image processing algorithm for the color measurement was developed. The color values of L*, a*, b* were calculated from the initial color values of RGB and then compared with the internal quality. Statistical analyses indicated that the internal quality was more highly correlated with the surface color than size of cherry tomatoes. Color image features were also investigated to detect external damage of cherry tomatoes. The value of (R value - R mean value)/R mean value was the most effective image feature for the detection of damaged areas on the surface of cherry tomatoes. The results of this study demonstrated the feasibility of color sorting process as an alternative of the conventional drum type size sorting system for cherry tomato industry.

In this paper. we propose a novel auto white balance algorithm which is one of the representative functions on cameras. White balance is the process of removing unrealistic color casts, which will make the captured white objects appear white. For white balance, we employ $CIEL^*a^*b^*$ color space which is the most complete color model available and is conventionally used to describe all the colors visible to the human eye and estimate the color difference on white objects with distribution of the image which is called the reference white estimation. For accuracy, we form groups or sets of pixels that are altered by the light sources and other elements. Moreover, Standard group is decided by judgment of specific-case images with the information of groups. Then, the reference white estimation is performed by the color sampling which is to choose all the accumulated pixels contained within the standard group. The color gain for image compensation by considering the color saturation is also computed. the proposed algorithm provides a significant performance.

The purpose of this study is to study the movie costume and color image through the movie"Vertigo". Firstly, looking into the clothing style and the color image of the characters expressed in the movie, Scottie who had the physical limitation had phobia of height, and he was expressed with the gray color to show his lethargic feeling from his physical limitation. And, after the death of Madeleine, it expressed his sense of loss and depressed mind through the blue color. The comparison of green and red color that was used to link the two characters in Madeleine and her substitution, Judy, mystified her, and the image of dreamy Madeleine has been inscribed to Scottie. In addition, the green color expressed her unstable mind. The clothing expression of Judy is expressed with her unstable mind through the detailed clothing, unlike Madeleine. And, the black color expressed the false identity of her and the Madeleine image of his own for Scottie. The type of clothing is expressed in separates suit and overcoat that are representative ones in 1950s, and black dress with the square neckline and others expressed the silence on conspiracy of Gavin and the false identity of her. Secondly, the color image expressed in the background in the movie as a special space for Scottie and Madeleine. The blue color image for Scottie was shown to be as space for death and the green image for Madeleine as a fantasy.

Importance of color in floral design has been emphasized for long time, but it is difficult to find out standardization of color for floral design and for educational system. Wedding bouquet is major and important part of floral design and it shows same problem. The research is concentrated on color image analysis of wedding bouquet designs which have been submitted for 'Interflora World Cup Competition' with the intention to utilize the study result as the basic information of floral design. Colors of wedding bouquets from 20 different countries were analyzed. All of designers chose high brightness and saturation more for designing the bouquets. Warm colors and cold colors have been taken in similar portion. Blue color has been rarely used and it is probably because of the rarity of blue flowers. This study shows each continent has different color preference. European designers used wide variety of colors while Asian designers preferred red color. From this study, we found that color image scales of wedding bouquets represent 8 images out of 12 representative images. Four exceptions are 'clean', 'elegant', 'gentle' and 'modern' images.

In this paper, we propose a novel method for improving defect-detection performance based on reconstruction of line-scan camera images using both the projection profiles and color space transform. The proposed method consists of RGB region segmentation, representative value reconstruction using the tracing system, and Y image reconstruction using color-space transformation. Through experiments it is demonstrated that the performance using the reconstructed image is better than that using aerial image for LCD surface inspection.

Due to the fast development in computer and communication technologies, a video is now being more widely used than ever in many areas. The current information analyzing systems are originally built to process text-based data. Thus, it has little bits problems when it needs to correctly represent the ambiguity of a video, when it has to process a large amount of comments, or when it lacks the objectivity that the jobs require. We would like to purpose an algorithm that is capable of analyze a large amount of video efficiently. In a video, divided areas use a region growing and region merging techniques. To sample the color, we translate the color from RGB to HSI and use the information that matches with the representative colors. To sample the shape information, we use improved moment invariants(IMI) so that we can solve many problems of histogram intersection caused by current IMI and Jain. Sampled information on characteristics of the streaming media will be used to find similar frames.

In the East color is deeply related to man's feelings or emotional status. This is relevant to the peculiar naturalistic thoughts of the East and concretely speaking is based upon the idea of Yin Yang and Five Elements that has dominated the spiritual world of the East. We can see costumes of the Three Kingdoms era or Koryo dynasty on the murals of ancient tomb presume their social backgrounds through remains of the past and find out the existence of Saekdong. Chosun dynasty shows a wonderful growth of fashion not only in dress but also in such accessories as patchwork wrapping-cloth and Saekdong which imply a lot on formation or color arrangement. Saekdong which we can see throughout many Eastern countries is a representative image that has been forming and expressing our race's color emotions for a long time. Saekdong to become worldwidely used. And this study has attempted modernistic expressions with Saekdong.

The aim of this research is to establish basic materials for fashion merchandising by observing the street fashion of the juveniles and by analyzing their wearing, coordination and fashion trend. We have taken the photograph of the street fashion of 202 male teenagers and 265 female teenagers in Busan, and analyzed in the category of style, item, color, pattern, materials, hair style, shoes and accessories. We have concluded that the most frequent items were shirts (male), turtle neck (female) and jeans. The main style was casual just as jumper-look, sweater-look, gardigan-look. The typical female fashions that were hip-hop-look, twin neat-look, trench coat-look, were more various than male. For the color coordination, contrast color coordination was more dominant than similarity color coordination. Dominant patterns were solid, and also check and stripe patterns were frequently found in upper garment. The representative materials were soft for upper garment, and hard for trousers. Male teenagers prefer middle-length hair style and female teenagers prefer long hair style. The juveniles in Busan are wearing sports shoes and leather shoes in similar frequency. Their favorite accessories are bag, muffler and hat.

Previous studies on color sensibility employed mostly general emotional and/or sensational words, and could not have a focus on the matter of 'color'. This study tried to collect sensibility words of color widely, and select representative words in a systematic way, with a result of 90 sensibility word list. 25 participants were asked to indicate how they feel on each item of the list when each of 22 colored light was projected on the screen. Factor analysis of data extracted 5 sensibility factors, such as mildness, neatness, splendour, dynamic, and weightiness. They were thought to represent color sensibilities more specifically, while having some similarities to, than those factors proposed previously. Issues on interpretation of factors and application of this result were discussed.
