A method and results of classification of 4 types metallic wear debris were presented by using their color features. The color image of wear debris was used (or the initial data, and the color properties of the debris were specified by HSI color model. Particle was characterized by a set of statistical features derived from the distribution of HSI color model components. The initial feature set was optimized by a principal component analysis, and multidimensional scaling procedure was used for the definition of classification plane. It was found that five features, which include mean values of H and S, median S, skewness of distribution of S and I, allow to distinguish copper based alloys, red and dark iron oxides and steel particles. In this work, a method of probabilistic decision-making of class label assignment was proposed, which was based on the analysis of debris-coordinates distribution in the classification plane. The obtained results demonstrated a good availability for the automated wear particle analysis.

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.

In this study, the colors and characteristics of Gwangbok-ro of Busan were analyzed in the standpoint of local images based on the examination of the facade designs of stores along the road of Gwangbok-ro, Busan a main street with massive population flow. To that end, the facades of stores, correlation with the city, color and locality were examined, and after the status of facade designs in Gwangbok-ro were identified through case survey by it, color images were analyzed. For color analysis, Munsell color system was used as basic tool. As a result of examining the colors in Gwangbok-ro area, the following status could be analyzed on 3 attributes of hue, brightness and chroma: First, analysis results of hue indicated that dominant color that covers 70% or more of the area represented mid brightness and low chroma in GY(36.1%) series, subsidiary color which covers 25% or more of the area mid brightness and low chroma in YR(26.5%) series, and accent color that covers less than 5% of the area high brightness and low chroma of GY(40%) series. Second, in brightness analysis, dominant color mostly represented mid brightness, subsidiary color mid brightness and accent color high brightness respectively. In particular accent color showed more intensive crowding phenomenon in high brightness. Third, as for chroma, dominant color, subsidiary color and accent color all are gathered in low chroma, however in small number of accent colors, peculiar high chroma appeared notable. In conclusion, the colors of Gwangbok-ro area analyzed based on the facade design of the stores along the road in this study were superficial colors that reflect the life of people in the area, artificial colors by improvement of the local environment. This study is meaningful in that the image of Gwangbok-ro was found through building colors in one part of the city Busan. It is judged that the study results would become useful as reference document in planning out environment colors later on.

The purpose of this study is to analyze the aesthetic factors in color combinations of house exteriors in hillside villages, Busan. The so-called 'Hillside renaissance' is a representative urban regeneration project in Busan. The towns in hillside area in Busan have developed colorful sceneries. But all the colorful sceneries are not the same. Each town has own color characters and different aesthetic color effects. This study is to determine the unique aesthetic components in color combination of Gamcheon and Daecheong. This study is based on the traditional color harmony theories. The analysis focuses, inter alia, on Moon-Spencer's 'Aesthetic Measure'. A house exterior color has relations with two neighboring colors in array. And those three colors with next two houses have again each three hue, value and chroma relations. This analysis is first to determine whether each sample color combination is harmonized, and if harmonized, next step to list which aesthetic factor is dominantly contributing to color harmony. And at last, to study the subcategorized sectors of each color components of the hue, value and chroma.

최근 의료 영상 분석(Medical Image Analysis)이나 영상 검색(Image Retrieval)을 위한 전처리(Preprocessing) 단계로 영상 분석(Image Analysis)에 대한 연구가 활발히 진행되고 있다. 본 논문에서는 영상 검색에서 색상 성분(Color Component)의 활용 방법을 제안하고자 한다. 이미지를 검색하기 위해 색상 성분을 기반으로 하고, 색상(Color)을 분석하기 위한 기법으로 CLCM(Color Level Co-occurrence Matrix)과 통계적 기법을 이용하고 있다. CLCM은 기하학적 회전 변환(Geometric Rotate Transform)을 통해서 색상 성분을 3차원 공간상에 투영(Projection)하여 공간 관계(Spatial Relationship)로부터 나타나는 분포를 해석하는 방법으로, 본 논문에서 제안하는 주제이다. CLCM은 색상 모델에서 만들어지는 2차원 히스토그램을 지칭하며 색상 모델의 기하학적인 회전 변환을 통해서 생성된다. 그리고 이를 분석하기 위한 방법으로 통계 기법을 활용하고 있다. CLCM과 유사하게 2차원 분포도를 사용하는 GLCM(Gray Level Co-occurrence Matrix)[1]과 불변 모멘트(Invariant Moment)[2,3] 같은 알고리즘은 2차원적인 데이터를 해석하기 위하여 기본적인 통계 기법을 활용하고 있다. 하지만 GLCM과 불변 모멘트가 각각의 도메인에 최적화되어 있다 하더라도 공간 좌표상에 존재하는 불규칙적인 데이터를 완전히 해석할 수는 없다. 즉 GLCM과 불변 모멘트는 기초 통계 기법만을 사용하고 있기 때문에 추출된 특징들의 신뢰성이 낮다는 것이다. 본 논문에서는 이러한 단점을 보완하여 공간 관계를 해석함과 동시에 데이터의 가중치를 해석하기 위해 전형적인 다변량 통계에서 사용하는 주성분 분석(Principal Component Analysis)[4,5]을 이용하고 있다. 그리고 데이터의 정확도를 높이기 위해서 3차원 공간상에 색상 성분을 투영하여 이를 회전시키면서 데이터의 특성을 다각도에서 추출하는 방법을 제시한다.
