  • The spectral color resolution of an image is very important in color image analysis. Two factors influencing the spectral color resolution of an image are illumination intensity and lens aperture for a selected vision system. An optimal combination of illumination intensity and lens aperture for color image analysis was determined in the study. The method was based on a model of dynamic range defined as the absolute difference between digital values of selected foreground and background color in the image. The role of illumination intensity in machine vision was also described and a computer program for simulating the optimal combination of two factors was implemented for verifying the related algorithm. It was possible to estimate the non-saturating range of the illumination intensity (input voltage in the study) and the lens aperture by using a model of dynamic range. The method provided an optimal combination of the illumination intensity and the lens aperture, maximizing the color resolution between colors of interest in color analysis, and the estimated color resolution at the combination for a given vision system configuration.

  • The purpose of this study is to confirm the international unique color sensibility according to the ethnic color preferences. The existing studies about color sensibility were investigated to analyze the international color sensibility. The countries were chosen according to its, strong regional and racial color. Also, the documents and websites about environment color such as structure color, natural feature color, traditional folk costume color and customary color names were investigated, and then, the international color sensibility was analyzed by using the color image scale. As a result of the analysis about the differences of color sensibility, internationally distinguished color sensibility was discovered. There were differences not only for the preference trend of hue but also for the tone or contrast of color among the selected countries. Especially, Great Britain had a strong preference for G categories that they preferred the warm-grayish color image. Russia has a preference for R, G, and B categories with the preference for the warm-clear image. Netherlands had a preference for R, Y, and PB categories and it preferred the cool-hard-grayish, warm-soft-clear image. Italy had a preference for R and Y categories and it preferred the warm-clear image. Morocco had a preference for R and B categories and it preferred the warm and cool, clear image. Japan had a preference for R, G categories and it preferred the warm-grayish image. Korea had a preference for R and B categories and it preferred the warm-soft-clear, and cool-clear image. With these results, the researcher concludes that the integrated analysis of the environment color and the traditional racial color factors are very persuasive methods to comprehend the international color sensibility.

  • 최근 암반공학 분야에서 영상분석기법 및 상용 영상분석장비의 활용이 활발히 이루어지는 추세이다. 그러나 영상의 획득 및 분석 단계에서 발생 가능한 오차들의 문제에 대해서 많은 부분 무시되어 왔으며 관련 연구 또한 미비하였다. 객관적인 암석영상의 분석 및 신뢰도 향상을 위해서는 암석영상에 적합한 컬러보정기법의 마련이 필요하다. 이에 본 연구에서는 암석영상에 대하여 표준컬러차트를 이용한 컬러보정기법을 도입하였으며, 화강암 시료를 대상으로 획득된 영상에 대하여 컬러보정과 오차분석을 수행하였다. 그 결과 암석영상들간의 상호 비교분석이 가능하였으며 또한 영상 획득 및 분석 단계의 신뢰도 향상을 꾀할 수 있었다.

  • The purpose of this study is to classify Avatar fashion style through analysis of on-line Avatar Mall and to propose color pallette and fashion contents from fashion color analysis. The literature research focused on investigating the notion, characters and types of Avatar and relation of Avatar and self-image, clothing image and color image. In data research, 4 on-line portal sites Avatar Malls were analyzed and Avatar fashion style was classified. In addition, Avatar clothing color was analyzed. The research of this study are as follows: Firstly, Avatar in the cyber space represents 'me' of the real states. Avatar fashion helps to represent Avatar Image and clothing makes human image and identity as a social sign. Color helps to constitute clothing impression and human image, therefore clothing and color are the important elements to express self-image through Avatar in the cyber space. Secondly, Avatar Malls of 4 on-line portal sites are very similar and confuse Avatar users because of no standard of fashion style classification. Accordingly, the standard of fashion style classification should be made by a fashion expert, and the specific characters of every on-line portal site should be emphasized. Thirdly, as a result of the analysis of Avatar's clothing, the clothing is divided into a real world clothing and an imaginary world clothing. There are daily clothes, uniform, event clothes, story clothes and fantasy clothes. As a result of the color analysis of Avatar clothing, White, Red, Red Purple colors and bright and vivid tone are generally used for Avatar clothing. This study is significant to classify Avatar fashion style systematically, to notify sensitive and delicate users' sign and to make Avatar fashion image emotional and high-quality.

  • The analysis has an objective of presenting a standard of human image making by producing results of characteristics and individual human image of each color appropriate for the personality through enneagram that is a personality analysis program. The study was done on 200 adults living in the whole country from Oct. 4 to Oct. 18th, 2004. In the survey, 11 colors were selected. The followings show the 9 personalities. 1.Instinct type preferred Blue(blue+navy) color. 2. Feeling type preferred Red(red+orange) color. 3. Thinking type preferred Yellow(yellow+green) color. The study results tend to match the expected preference of color for each personality. In the Human image management, the individual distinction of 3 personality classes need to be analyzed in order to develop individual and created personality by preferred color. It is very important to examine the image for color each personality pursuits through the analysis. Also, there need to more participants of the study so that results can be analyzed more inclusively and there should more in-depth study.

  • This study examines the color image of uniform of airline cabin crew according to the demographic characteristics of the customer and demonstrates how it affects the cognitive image of airlines. Adjective adjectives were derived for uniform color images of all eight airlines in Korea and analyzed the image of airline brand color. Based on the analysis of color images, the difference in perception according to the demographic characteristics of passengers was analyzed. When the colors of airline uniforms are mainly blue, sky blue, white and ivory, they have a lot of trust, neat and elegant images. Uniforms with primary colors such as red, orange and green beans are found to have a lot of cheerful, developmental and enterprising images. In addition, the empirical analysis of the impact of the customer's cognitive perception and favoritism on the uniform color image of the airline crew showed that the more positive the airline's positive perception of the uniform color image, the more positive the cognitive image is. In other words, the empirical analysis revealed that the airline's uniform color image, its cognitive image of the airline, and its popularity have significant positive relationships.

  • 색체이미지의 가치평가를 위한 객관적이고 구체적이며 우리나라 실정을 반영할 수 있는 평가척도의 개발은 색채기획의 중요성과 함께 시급한 문제임에도 아직 활발한 색체기획의 중요성과 함께 시급한 문제임에도 아직 활발한 연구가 이루어지지않고 있다. 따라서 본연구는 색채이미지의 척도 개발을 위한 기초연구로서 선행된 연구들을 수집하여 색채이미지의 개념 및 연구경향과 연구방법론에 대해서 연구대상 및 표집, 자극도구 및 분석방법, 평가척도의 측면에서 종합적으로 분석하였다. 의류상품의 색채기획을 위하여 색채 이미지에 대한 다양한 주제의 연구와 연구대상 선정을 여러계층으로 확대시켜 볼 필요가 있다. 연구내용에 따라 자극도구의 신중한 작성과 적절한 분석방법의 선택이 요구되며, 분석방법은 주로 이미지의 인자를 추출하는 요인분석이 사용되었다.
