Color plays a fundamental and important role in various areas, it has become important to choose colors which fits the purpose and also harmonious. The goal of this study is to reduce the difficulties of choosing the color and get the colors with high satisfaction when users want to choose multiple colors. To do this, we extracted and analysed a large number of colors in color database. And We designed an interface applied to high preference color combination rule. We also evaluated the usability and user satisfaction of the interface. The results showed that the functionality of the developed interface is more useful and is more satisfied than that of the conventional interface.

The purpose of this study is to find out the effect of office workers' motivation to choose clothing and makeup colors on appearance satisfaction and self-esteem. The subjects of this study were working women working in Chungcheong-do for two weeks from July 15, 2023 to July 29, 2023, and 696 sampled copies were used for the final analysis. Frequency analysis, factor analysis, reliability analysis, (one-way)ANOVA, and post-verification (Scheffe's) were handled using the SPSS 26.0 program, and office workers' clothing. Correlation analysis, simple regression, and multiple regression were performed to find out the correlation between makeup color selection motivation, and the statistical significance level was p<.I set it to 05. Through this research procedure, the following conclusions were drawn. First, it was found that the motivation of office workers to choose clothes color had a positive (+) effect on appearance satisfaction. Second, office workers' motivation for choosing makeup colors was found to have a positive (+) effect on appearance satisfaction, and physical attractiveness was found to have a positive (+) effect on situational factors. Third, it was found that the color choice of clothes of office workers had a positive (+) effect on self-esteem. Fourth, It was found that the motivation of office workers to choose makeup colors had a positive (+) effect on self-esteem.

자연계의 많은 생물들은 의사소통이나 분위기 표현, 위장 등을 하기위해 자신의 색을 바꾸는 것으로 알려져 있으며, 현재 많은 연구자들이 이러한 자연 현상으로부터 영감을 받아 생체모방 구조와 메커니즘을 이용한 바이오센서를 개발하고 있다. 하지만 기존의 컬러센서는 수용체 개발에 있어 복잡한 디자인, 어려운 합성 방법 및 낮은 감도와 저선택성 등의 한계점을 가지고 있다. 이에 본 연구에서 우리는 바이러스(M13-박테리오파지)를 기반으로 한 신개념 고감도 고선택성 컬러센서를 개발하고자 한다. 우리가 개발하고자 하는 컬러센서는 자가 조립방법으로 만들어진 나노 구조체로 형성되어 있으며, 다양한 종류의 화학물질이나 오염물질을 감지할 수 있다. 이 컬러센서는 아주 낮은 농도의 휘발성 유기화합물(volatile organic compounds)을 감지해 색변화를 보였으며, 다양한 독성 물질이나 방향족을 가진 화학 물질을 감지할 수 있었다. 따라서 우리가 개발한 컬러 센서는 국가의 안보나 국민의 건강을 증진시키기에 아주 유용할 것으로 보인다.

Clothing color for animation characters is very important in expressing a given characters image and characteristics. Consequently, in this paper, we propose a tool that allows an easy and simple selection of clothing color combinations in conjunction with previous color combination image research (color image chart). This tool has two functions, The first allows the user to search what color best fits a given image, and the second calculates which image is closest to the color that user has chosen. This tool was developed so it can be used over the web, and was used to verify whether the color combination for Disney and Dream Works animated characters' clothing has been selected appropriately according to the character's image, as determined through a survey.

In this paper, the color matching algorithm is Proposed for stitching machine. The matched embroidery color threads are selected by using the proposed algorithm from a computer files which is designed on the computer or scanned from the drawings designed by an artist. The proposed algorithm finds the best matching nearest colors from the given embroidery color threads . The multiple candidates owing to have the equal distance in the CIE color space are further processed to find nearest dominant color. The color dithering method will be useful for reproducing original design with high fidelity.

Mass-customization is fast growing a segment of the apparel market. 2D Virtual wearing system is one of visual support tools that make possible to sell apparel before producing and reduce the time and costs related to product development and manufacturing in the world of apparel mass-customization. This paper is related to fabric color mapping method for 2D image-based virtual wearing system. In proposed method, clothing shape section of interest is segmented from a clothes model image using a region growing method, and then mapping a new fabric color selected by user into it based on its intensity difference map is processed. With the proposed method in 2D virtual wearing system, regardless of color or intensity of model clothes, it is possible to virtually change the fabric color with holding the illumination and shading properties of the selected clothing shape section, and also to quickly and easily simulate, compare, and select multiple fabric color combinations for individual styles or entire outfits.

한의학의 증상을 파악하는 한의 변증 진단에서 혀의 형태와 색상을 파악하는 것에서 설질과 설태의 색상을 파악하는 것이 핵심이다. 혀 촬영 장치로 촬영하더라도 조명의 빛 종류와 빛 강도, 위치에 따라 컬러가 변환됨에 따라 혀 취득장치의 컬러교정이 필요하다. 컬러교정을 하지만, 오버피팅, 측정 오류와 노이즈 또는 색상 공간의 불균형으로 컬러의 왜곡이 발생할 수 있다. 이 연구에서는 24개의 patch 중에서 오류를 최소화할 수 있는 patch를 선정하는 최적화의 방법을 제시하려 하였다. 24개 patch 중 몇 개의 선택한 patch의 평균값을 구하여, 기준 값으로 변환시키는 변환 행렬을 구하고, 교정 값을 구하고, 교정된 24 patch 값의 평균과 기준 값과의 오차를 구하여 최소가 되는 변환 행렬을 구하였다. 이 방법은 컬러 챠트의 개수를 줄여 장치의 부피를 줄이는데 활용될 수 있다. 또한 이 방법은 외부의 빛이 차단된 촬영장치에서 활용되었지만, 조명조건이 안정된 개방된 공간에서도 스마트폰을 이용하여 촬영하는데 활용 가능할 것으로 예상된다.

Purpose: The aim of this study was to investigate the effect of improving read speed with color filter or without color filter to improve reading disorder of teenager who were diagnosed as Meares-Irlen syndrome through survey inspection with Meares-Irlen syndrome visual stress (MISViS) score. Methods: MISViS subjects were selected from screening survey MISViS results given above 2.13 in the clinical criteria scores (MISViS score). Reading speed were measured quickly and efficiently the rate of reading via test in which randomly ordered common words are read aloud during a minute. Each of the subjects were worn a filter of the lowest concentration in each color filter group composed of 15 groups. Results: MISViS score of MISViS group and control group were 2.57 and 0.66, respectively. Results of reading speed with filter and without filter in MISViS group were $102.27{\pm}27.86$ wpm and $118.87{\pm}26.99$ wpm (p=0.001), respectively, as well as were $132.93{\pm}6.88$ wpm and $133.43{\pm}6.64$ wpm (p=0.131) in the normal group. Associated with error changes with filter and without filter between two groups, skipping in MISViS Group were from $0.25{\pm}0.62$ times to 0 times (p=0.191), Errors were from $1.83{\pm}1.69$ times to $0.17{\pm}0.38$ times (p = 0.004) and, repetitions were 0. skipping in control group were 0 times, errors were from $0.21{\pm}0.43$ times to $0.07{\pm}0.27$ times (p=0.336) and, repetitions were from $0.14{\pm}0.36$ times to 0 (p=0.165). The filter of blue series chosen in MISViS group had higher percentage (40%), whereas, subjects in normal group were more likely to prefer the filter of gray color (29%). Conclusions: This study showed that MISViS score have been used as a significant diagnosis for Irlen syndrome screening. This study found that wearing suitable color filter for MISViS patients were useful to improve learning with regard to reading. Unique color filter selection for MISViS subjects must be carefully considered since fit color filter are different personally.

Pattern recognition is the study of how machines can observe the environment, learn to distinguish patterns of interest from their background, and make sound and reasonable decisions about the categories of the patterns. Color image consists of various color patterns. And most pattern recognition methods use the information of color which has been trained and extract the feature of the color. This thesis extracts adaptively specific color feature from images with several limited colors. Because the number of the color patterns is limited, the distribution of the color in the image is similar. But, when there are some noises and distortions in the image, its distribution can be various. Therefore we cannot extract specific color regions in the standard image that is well expressed in special color patterns to extract, and special color regions of the image to test. We suggest new method to reduce the error of recognition by extracting the specific color feature adaptively for images with the low distortion, and six test images with some degree of noises and distortion. We consequently found that proposed method shouws more accurate results than those of statistical pattern recognition.
