The Joint Photographic Experts Group (JPEG) is a standara still-image compression technique, established by the International for Standardization (ISO) and International Telecommunication Standardization Sector (ITUT). The standard is intended to be utilized in the various kinds of color still imaging systems as a standard color image coding format. Because JPEG is a lossy compression, the decompressed image pixel values are nto the same as values before compression. Image of JPEG compression is often made to JPEG recompression at saving to apply JPEG compression of color image. In general, JPEG is a lossy compression and compression image is predicted to be varied image quality according to recompressed Q-factor. Various distortions of JPEG compression and JPEG recompression has been reported in previous paper. In this paper, we compress four difference color samples (photo image, gradient image, vector drawing image, text image) according to various Q-factor, and then compressed images are recompressed according to various Q-factor once again. As the results, we inspect variation of quality and file size of recompressed color image, and ensure the optimum recompression factor.

The purpose of this study is to study the movie costume and color image through the movie "The Aviator". Firstly, looking at the costumes of main characters and their color images expressed in the movie, one extreme of Hughes' image to another was expressed in order to show his extreme inner world by using the light-dark contrast rather than specific colors as the base. The gold color used to express the image of Hepburn represented an image expressing her intellectual elegance. As for her dress silhouette, the taste of intellectual elegance was displayed by a dress whose back was exposed with a grownup-style feminine silhouette or one with drapes and pleats ornaments. To express Gardner's image; that is, her alluring charm and glow, a vivid red color was used. As for her costume, her splendid and fascinating image was expressed by the 40s' rectangular- shouldered tailored suit, exotic peasant blouse and showy accessories. Secondly, the color image expressed in the background in the movie as a special space for Hughes. The red color image of screening room was shown to be as a space for passion and desire and the green color image of men’s room as a space for stability and rest.

There has been an enormous emergence of imaging systems dedicated to hardcopy and softcopy color-appearance comparisons. Pre-press industry use the CRT as a soft proofing device to preview and aid with color corrections and changes before producing the final printed image. Color DTP system is required an accurate image-matching between CRT-image and printed image. In other to develop the color DTP,CRT calibration and CRT color transform to CIE color system are necessary. In this paper, we described a method CRT color transform to CIELab color system using RGB image raw data. Experimental results show that described method is useful valid of color image matching.

Public uniforms play an important role in creating the color and image of urban environment beyond the level of simple working clothes for unity and practicality. Hence this study aims to compare and analyze the color characteristics and images of the police officer, fire fighter, and street cleaner uniforms at home and abroad to guarantee the wearer's safety, increase convenience and agreeability, and give emotional satisfaction to citizens in harmony with urban environment color as public uniforms. For study methods, literature review investigated urban environment, color, and uniforms as public design. Empirical study extracted color data from the public worker uniforms of the world's top 20 cities selected by 'Newsweek' in 2010 and analyzed their colors, tones, and color images. The results of this study are as follows. The most common color for police uniforms were PB(dk) as the main color, PB(p) as the sub color, and Wh as the accent color. For fire fighter uniforms, PB(dkg) was the most common main color; GY(v), as the sub color; and ItGy, as the accent color. The most common color for street cleaner uniforms was YR(v) as the main color; GY(v), as the sub color; and mGy, as the accent color. As a result of analyzing color images of these uniforms, it was found that police uniforms commonly used a modern image; fire fighter uniforms commonly used a natural image and a cool casual image; and street cleaner uniforms commonly used a casual image. As examined above, the color of public uniforms suitable for urban environment and job characteristics is very important to establish the image of public institutions, as well as to create an urban image.

The purpose of this study was to examine the effects of interior color and product volume of clothing shop on consumer's store image and preference for a clothing shop. The research methodology was a survey questionnaire and the subjects were 516 university students in Daejeon, Korea. The measuring instruments were stimuli and self-administrated questionnaire. The stimuli were 7 pictures of clothing shop including interior color and product volume variables, and the self-administrated questionnaire consisted of semantic differential scales for store image, store preference, and subject's demographic attribution. The data were analyzed by t-test, ANOVA, MANOVA, Duncan's multiple range test, based on SPSS program The results were as follows: first, in clothing shop's interior colors affecting store image and preference for clothing shop, white color gave a casual, sophisticated, characteristic, and attractive image to the shops, and brown color gave an elegant, sophisticated image, while black color gave a sophisticated, uncomfortable image, and gray color gave a less positive image to them than other colors. Subjects preferred white, brown, and black color in the order. Second, clothing shop's products volume also affected consumers' store image and preference. Its small volume gave a more sophisticated, elegant image than other volume levels, and subjects preferred small and medium volume of clothing products to their large volume. Third, the effects of shop's interior color and clothes' product volume on store image were different depending on subject's sex. The results revealed that clothing shop's interior color and product volume are important VMD components affecting consumer's store image and preference, and consumer's sex has to be considered to understand the effects of VMD components on clothing shop image.

Machine vision system was used for analyzing leaf color disorders of tomato plants in a greenhouse. From the day when a few leave of tomato plants had started to wither, a series of images were captured by 4 times during 14 days. Among several color image spaces, Saturation frame in HSI color space was adequate to eliminate a background and Hue frame was good to detect infected disease area and tomato fruits. The processed image ($G{\sqcup}b^*$ image) by OR operation between G frame in RGB color space and $b^*$ frame in $La^*b^*$ color space was useful for image segmentation of a plant canopy area. This study calculated a ratio of the infected area to the plant canopy and manually analyzed leaf color disorders through an image segmentation for Hue frame of a tomato plant image. For automatically analyzing plant leave disease, this study selected twenty-seven color patches on the calibration bars as the corresponding to leaf color disorders. These selected color patches could represent 97% of the infected area analyzed by the manual method. Using only ten color patches among twenty-seven ones could represent over 85% of the infected area. This paper showed a proposed machine vision system may be effective for evaluating various leaf color disorders of plants growing in a greenhouse.

It is very necessary and important that color image language is given to each coloring to highten efficiency on applying color scheme. For that in this research, literature cited and survey are carried out to select languages on the Korean's color-image connected with color scheme at the same time, and I did my best to objectify the subjective color image through verifying related experts. As the result of research, I classified the color image into 14 categories; A. energy or dinamic, B. harmony, C. order, D. style and fashion, E. mystery, F. Practicalty, G. dignity, H. gorgeousness, I. the sense of sight, touch, taste, hearing, J. complexity, K. sexuality and growth, L. standard, M. static and lyricism, N. simplicity to promote user's usefulness. For the user's convenience on color plan, the work to propose color scheme concided with the selected color-image languages is deferred till the follow-up research.
