The image identification methodology associates an image with a unique identifiable representation. Whenever the methodology regenerates an identifier for the same image, moreover, the newly created identifier needs to be consistent in terms of representation value. In this paper, we discuss a methodology for image identifier generation utilizing luminance correlation. We furthermore propose a method for performance enhancement of the image identifier generation. We also demonstrate the experimental evaluations for uniqueness and similarity analysis and performance improvement that have shown favorable results.

This study develops textile pattern design ideas created through the visualization of music. Methods of auditory and synesthesia were employed to analyze various attributes of popular music genres and appoint language image, shape image, and color image to obtain their interrelationships. This study provides data that can be used to express emotional images on textile print pattern designs. This research used different genres of popular music as stimuli. The language image was extracted and introduced to the overall color scheme; in addition, the color image was verified. The analysis of the color image was executed by applying it with the color set image scale of I.R.I colors. Then, the color image of the target genre of popular music was examined and analyzed through a color tone system. The preference in shape image was realized through visual images based on basic principles of points, lines, and sides composition; subsequently, an analysis of the emotional image of popular music followed. An examination of the emotional images of different popular music genres have led to the discovery that language image, color image, and shape image all share a common emotional image. There was also a realization that similarity and interrelationship exists in language, color, and shape images experienced by listening to popular music.

This paper proposes a scheme of global image contrast enhancement using local contrast improvement. Methods of global image contrast enhancement redistribute the image gray level distribution using histogram equalization without considering image properties, and cause the result image to include image pixels with excessive brightness. On the other hand, methods of the block-based local image contrast enhancement have blocking artifacts and a problem of eliminating important image features during an image process to reduce them. In order to solve these problems, the proposed method executes the block-based histogram equalization on temporary images that an input image is divided into various fixed-size blocks. And then it performs the global contrast enhancement by applying the global histogram equalization functions to the original input image. Since the proposed method selects the best histogram equalization function from temporary images that are improved by the block-based local image contrast enhancement, it has the advantages of both the local and global image contrast enhancement approaches.

This study is aimed at finding out the self-perception and value of clothing they wear to today's businessmen who work in a fast-growing global network society and for developing a suitable image consulting program for businessmen. The purpose of this study is to categorize businessmen into personality types, and then analyzing purchase behaviors for clothing and image perception, self-image satisfaction among categorized groups. The participants of this study are 320 businessmen who are from 20's to 50's and working in Seoul. A total of 302 questionnaires were used for the survey of this study. The questionnaire is composed of 3 different parts as follows: 1) personality types, 2) purchase behaviors for clothing and image perception, 3) self-image satisfaction. The methods of this study are frequency analysis, descriptive analysis, factor analysis, variance analysis, cluster analysis, t-test and reliability analysis. In conclusion, an image consulting education program for businessmen has to be based on one's own personality type, current fashion style and image perception. Each person has to be provided a unique direction to increase his self satisfaction, which will result in improvements in both personal image satisfaction and social satisfaction. These changes will ultimately become the driving force of career life.

This study examined the impacts of the cultural proximity of Chinese consumers on the image of both country and product, and investigated how they are related to purchase intention of Korea fashion. Subjects were Chinese female consumers in their 20s and 30s, living in Yangtze River delta and Seoul. The results of the study were as follows: 1) The cultural proximity had a significant influence on the country image and fashion product image. Chinese consumers with more emotional proximity had more positive attitude towards country image, such as politics, economics, technology, cultures and people image. And consumers who had higher interest in Korea and Korean culture evaluated the quality, design, value and reputation of Korean fashion more positively. 2) Chinese consumers with positive attitude towards people, technology and culture image seemed to prefer fashion product. Specifically, the dimensions of country image had a different influence on the fashion product image such as product quality, design, value, reputation. 3) The Korea country image and fashion product image had also affected on purchase intention of Korean fashion products. Consumers with positive attitude towards people and technology image had higher purchase intention of Korea fashion products. And consumers with positive attitude towards reputation, value and design of fashion products had higher purchase intention of fashion products.

Image interpolation is a method of determining the value of new pixel coordinate in the process of image scaling. Recently, image contents are likely to be a large-capacity, interpolation algorithm is required to generate fast enhanced result image. In this paper, fast multiple mixed image interpolation for image resolution enhancement is proposed. The proposed method estimates expected 12 shortfalls from four sub-images of a input image, and generates the result image that is interpolated in the combination of the expected shortfalls with the input image. The experimental results demonstrate that PSNR increases maximum value of 1.9dB, SSIM increases maximum value of 0.052, and the subjective quality is superior to any other compared methods. Moreover, it is known by algorithm running time comparison that the proposed method has been at least three times faster than the compared conventional methods. The proposed method can be useful for application on image resolution enhancement.

Image sticking, the phenomenon that the previously displayed pattern still remains after the image is changed into different image, is one of the most serious problem in realizing high picture quality. There are various methods decreasing the image sticking phenomenon. In this paper, we have tried to decrease boundary image sticking by reducing the discharge concentration phenomenon in the boundary of pattern using the new driving method that is applied to bias in the address electrode.

The purpose of this study is to examine the influence of external image and self perfectionism on the depression. The survey collected 240 subjects from 3 university students in Seoul, Korea. The research period was from May to June of 2011 and the collected data were analyzed using the SPSS 15.0. As a result of this research, those with lower self image level, those with higher self perfectionism increased the depression level. It is necessary to develop programs for university students considering the fact that external image and self perfectionism influence on the depression. Moreover, it should be developed that solutions can decrease psychological pressure and overcome overwhelming expectation.

Recently as new digital media like High Definition Television (HDTV) have been made popularization. However In case of image quality characteristics of AC PDP, the problem especially raised is 'image sticking' phenomenon, the phenomenon that the previously displayed pattern still remains after the image in realizing high picture quality. In this paper, Image sticking Phenomena observed in AC PDP are defined and classified, these effects are analyzed as luminance, color purity through chromaticity diagram and firing voltage state using light waveform.
