VR and AR contents provide a rich user experience [1]. Realistic content with human computer interaction and immersion provides an improved user experience, but there is a limit to producing all elements realistically. In this study, we propose a method to advance the rendering of immersive content using background color information [2]. First, the elements necessary for Kelvin temperature rendering are derived from the color and background as context elements, and the rendering effect has been realized in the soap bubble. For soap bubbles Kelvin temperature rendering, the average color of the background is extracted and the color with the highest similarity is applied by comparing the main color and Kelvin temperature.

The elderly population of Korea has been significantly increasing due to advances in public health, medical care, and quality of life. Social and economic influence of the elderly population has been also increasing. A elderly people become more interested in their appearance and clothing than before, clothing plays an important role in the elderly women's everyday life. The objectives of the research are to explore the life satisfaction, appearance satisfaction, clothing satisfaction, and clothing design preference of 416 women aged 55 years and older were residents of Seoul. Data were gathered through survey using a self-administered questionnaire from November, 1994 to January, 1995 in 8 senior schools and 3 senior centers which were scattered in Seoul. Descriptive statistics, t-test, and factor analysis were used in analysing the data. The results of this study indicated that life satisfaction have a positive relationship with clothing satisfaction. The respondents were divided into tow groups by life satisfaction. The higher life satisfaction group preferred skits and formal wear to the lower. But, two groups did not show any significant differences in terms of the colo preference, motif preference, and fabric preference. The result of factor analysis divided appearance satisfaction into body satisfaction and face satisfaction. Body satisfaction had a positive relationship with clothing satisfaction. And the group of lower physical satisfaction showed lower satisfaction in apparel fitness. Also the face satisfaction had a positive relationship with clothing satisfaction. The group of higher physical satisfaction preferred skirts and foraaml wear compared to that of lower physical satisfaction. The color preference and motif preference between two groups showed no significant difference. And the group of higher physical satisfaction preferred fabric that enhances the clothing style. Also, the group of higher ace satisfaction preferred fabric that enhances the clothing style. However, there was no significant difference in the color preference and motif preference between tow groups. The findings of this study amy contribute to knowledge about clothing satisfaction and preference of elderly women in Seoul since there have been few studies, and be useful to apparel manufacturers as well s clothing researchers. Also, research subjects of this study could be extended to aged men and various regions.

The research was done against female workers in public officers to find out the actual conditions and usage of uniforms worn in government and other public offices, to find out the degree of their satisfaction for it's appearance, costs, functions and representation. The research was done by questioning 402 female workers about their uniforms in various government and other public offices and the results analysed from the research are as it follows below. 1. The shape of uniforms in public offices were mostly in three piece(jacket+vest+skirt) shape, many of them in gray color and the material were made of blended fabrics. 2. The satisfactory garde of the uniform couldn't even reach the level of '3 point', in which it is easy to tell that the workers had low satisfaction with their uniforms. The level of satisfaction in it's appearance, functions, costs and representation were below average, the rankings starting with functions, representation, appearance, costs and it was shown that the most satisfied category was in it's functions and the lest in costs.

PM OLED has the line-disturbance when eyes can detect the driving line status in the shaking situation. It is closely related with the lighting intensity and the lighting time during the line driving. .In this paper we suggest the frame part method for eliminating lineflash appearance. Frame part is a driving method of PM OLED, which divides one frame into several inner-frame parts to reduce the color interference between closely related pixels and to lessen the lineflash appearance which disturbs viewer to perceive the images. Frame part groups one frame into several inner-frame parts and have inner-frame rate higher than the frame rate. Frame part could be used in most of applications in PM OLED systems to enhance the total performance of screen quality.

The denoising and reconstruction of color images are increasingly studied in the field of computer vision and image processing. Especially, the denoising and reconstruction of color face images are more difficult than those of natural images because of the structural characteristics of human faces as well as the subtleties of color interactions. In this paper, we propose a denoising method based on PCA reconstruction for removing complex color noises on human faces, which is not easy to remove by using vectorial color filters. The proposed method is composed of the following five steps; training of canonical eigenface space using PCA, automatic extracting of face features using active appearance model, relighing of reconstructed color image using bilateral filter, extraction of noise regions using the variance of training data, and reconstruction using partial information of input images (except the noise regions) and blending of the reconstructed image with the original image. Experimental results show that the proposed denosing method efficiently removes complex color noises on input face images.

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.

Compared to the barcode which is being widely employed to store information on products, the color code may find more various applications because of its favorable appearance and larger possible number of combinations. However, the color values read in practice may suffer from distortions from environments and devices. In this paper, we propose efficient ways to reduce the effect of such distortions and to detect color codes. for which we apply the Right Hand on Wall (RHOW) algorithm originated from the area of the maze search. The color codes used in this paper have high values of Hue and Saturation components and have a circular shape. We first preprocessed the images to detect candidate areas of color codes, and then applied the RHOW algorithm to determine optimal coordinates of rectangles enclosing the areas. As a result, we could obtain accurate coordinates of color codes by using the RHOW algorithm.

Colors have been derived from the observed optical spectrum of Mars and Jupiter. It is known that the planets and the Moon emit reflected sunlight and thus their spectra are similar to the spectrum of solar radiation. The question was then why is the color of Mars different from that of other planets, i.e. red, although it would share the same spectrum of reflected sunlight. Can one derive color from the spectrum? Therefore, we observed the optical spectra of the scattered sunlight in day time for the Moon and Mars using a 1-D array spectrograph on the 12-inch reflecting telescope in the Korea Science Academy of KAIST in Busan, Korea. We adopted the International Commission on Illumination (CIE) in 1931 of three spectral sensitivity peaks for the human eye in short, medium and long wavelengths in visible light. The observed spectra were imposed on CIE sensitivities and the color detected by the human eye was derived. The Mars spectrum represents red color and the Moon white. It is a similar color to that which a human would see. This result means that color is easily derived from astronomical spectra. The appearance of the planets surface can be determined for Mars, which is the result of iron oxide.

In this paper we propose content based image retrieval method using sequential clustering and projection information. Proposed method uses the mean of color in clustered color regions by sequential clustering and the projection information in each clustered color regions, which combines spatial information with color information in images efficiently. The experimental results showed that the proposed method retrieval efficiency improved 11.6 percent over conventional methods. In addition, the proposed method robustly tolerates large changes in appearance and shape caused by changes in viewing positions, camera zooms, etc.

An object's color and intensity are determined by its spectral reflectance and illumination. Therefore, the illumination plays a key role in forming the appearance of the object in a scene. In this paper, we focus on color distinction of objects and derive the optimal illumination conditions to maximize the distance between objects in the RGB color space. As a practical approach the optimal illumination is composed by deriving the optimal linear combinations given a set of LED light sources. The effectiveness of our approach is shown through experimental results using an endoscope system.
