The purpose of this study is to analyze the objective preference and satisfaction for the current basic educational environment as well as to suggest the solution by reducing the distance between color theory and the actual situation. The data collected in this study are 195 nursery school teachers and parents from six nursery school with similar color environment. Semantic differential developed by Osgood(1957) as analytic method is applied to analyze the psychological meaning for the color preference among them. The results of this study are as follows; First the nursery school teachers and parents are satisfied with the light tone color palette. Second the nursery school teachers and parents agree with consistent response for the middle tone color palette. Finally the nursery school teachers and parents show different inconsistent response for the vivid strong color palette.

This paper discusses an approach for detecting a new edge in color images. The color image is to be represented by a vector field, and the color image edges are detected as differences in the local vector statistics. This method is based on the calculation for the vector angle between two adjacent pixels. Unlike Euclidean distance in RGB space, the vector angle distinguishes the differences in chromaticity, independent of luminance or intensity. The proposed approach can easily accommodate concepts, such as variable template edge detection, as well as the latest developments in vector order statistics for color image processing. In this paper, it is used not a conventional fixed template operator but a variable template operator The variable template is implemented and experimental results for digital color images are included.

본 논문에서는 자수로봇 제어를 위한 컬러처리 매칭방법을 제안하였다. 디자이너가 작업한 작품을 스캐너를 통하여 입력하거나 또는 컴퓨터 그림파일로 직접 입력받고 자수로봇을 통하여 재현하기 위하여 자수 로봇용 색실과 매칭되는 컬러를 본 논문에서 제안한 방법을 통하여 선택한다. 본 연구에서는 사용가능한 색실의 컬러 중에서 가장 유사한 색실을 찾는 방식으로 원본에 근접한 컬러를 찾는 방법을 제안하였다. CIE 컬러공간에서 근접한 컬러가 복수개인 경우 우월 컬러를 검출하기 위한 처리과정을 추가한다. 컬러 디더링 방법을 사용하면 좀더 충실한 컬러를 재현할 수 있을 것이다.

If we are to analyze certain chromatic phenomena, we must first know what “color” is； we must identify its essential characteristics in an effort to achieve a more rational comprehension of visual phenomena in general. What is difficult for most observers to grasp is that seeing colors is no different than seeing shapes. Indeed, all aspects of the objects in the world surrounding us-shape, size, distance, movement, as well as color--are seen via our perceptual system. (omitted)

This paper proposes a new color feature and a corresponding distance measure for content-based retrieval of design images such as trade marks, pattens, logos, textile images, and icons. Simulation results with textile images show that the proposed method outperforms the traditional color-based retrieval methods which was originally proposed fer content-based retrieval of natural images.

본 논문에서는 컬러 정보인 컬러비와 형태학적 정보인 코너점 및 거리비를 이용한 교통표지판 영역추출 시스템을 제안한다. R G, B 성분들의 컬러비를 기반으로 생성한 이진영상에 대해서 불림 연산처리와 마스크를 이용한 코너점 및 중심점 검출에 의해 후보영역을 추출한다. 다양한 형태의 교통표지판 영역은 후보영역의 중심점을 기준으로 형태학적 정보인 거리비를 이용하여 추출한다. 실험결과, 제안한 시스템은 크기 및 위치에 불변하며, 삼각형, 원, 역삼각형, 사각형 등의 다양한 교통표지판과 밝기값의 차이가 큰 낮과 밤 영상에 대해서도 정확한 영역추출이 가능하였다. 또한, 높은 정확성과 빠른 처리속도를 보였다.

PURPOSES : The purpose of this system (Rear Lighting System) is to provide illumination for the driver to operate the commercial vehicle safely after dark in highway, to increase the conspicuity of the vehicle, and especially be suggesting the finest observable improvement method, depending on color and pattern of rear lighting system of truck for midnight highway traffic. METHODS : Rear lightning system as an improving way for forward commercial vehicles lighting the securing sight from human factors and the surrounding environment in midnight driving. For this one, basic materials were collected from the data analysis about many types of problems, and filed investigation for establishing Driving Simulator. also taking statistic test to human volunteers after finding recognizable distance of them. RESULTS : As a result, color with the highest visuality is amber followed by green-red-blue as in order for all road types. Especially almost no difference is found between red and green, also when the light is turn off, recognizable distances is wide difference compared to turn on the light. One more thing about study per pattern, upper and entire lighting have similar recognizable distances, but under lighting shows short distance with difficulty securing sight from medians. And straight section shows similar recognizable distances. By finding visuality improvement method depending on color and pattern of supplement taillight, it is expected to suggest quantitative judgement standard for introducing regulation and improvement of supplement taillight. CONCLUSIONS : Night time vehicle conspicuity to the rear is provided by rear position lamps. this study is showed that the color of light ramp is not important to be safe driving, most important is to turn on the light, recognizable distances is big different compared to turn off the rear light, so when the drivng dark in highway, have to turn on the light for reducing risk.

본 연구는 제주도에서 자생하는 새우난초 3개체, 금새우난초 3개체 그리고 변이종 14개체를 포함하여 총 20개체를 화색에 따라 분류하고 유전자지도를 작성하여 QTL분석을 하였다. 화색은 새우난초가 어두운 자색으로 CIE Lab값이 $40{\sim}50$ 정도였으며, 금새우난초는 황색으로 $110{\sim}130$ 정도였고, 변이종 개체들은 새우난초와 유사하거나 다소 높았다. PCR 결과 얻은 polymorphism이 인정되는 154개 marker에 대한 분리비 적합도 검정에서 51개 marker에서 5% 수준의 유의성이 인정되었으며, 유의성이 인정된 51개 marker 중에서 새우난초 type은 37개, 금새우난초 type은 14개 였다. Polymorphism이 인정된 154개 marker에 대하여 MAPL program을 이용하여 이들 marker 상호간의 연관관계를 분석한 결과는 16개의 연관군과 1개의 독립군으로 구분되었으며, 이들 연관군에 대한 분자연관지도는 전체 group의 크기가 220.4 cM (centi Morgan)이고, marker간의 평균거리는 3.3 cM이었다. 양적 형질에 대한 분자연관지도상의 QTL 분석 결과, LOD 3.0 이상인 화색과 설판색의 QTL은 각각 3개와 1개였다. 이상에서 얻어진 자료는 새우난초 속의 화색 연구에 도움이 될 것으로 사료된다.

For the development of 100[W] stage lighting, quantitative and uniform color mixing that applied through color adopted Simple-Inverse matching so that color mixing can be possible along Black Body Locus. R,G,B(Red, Green, Blue) LED(Light Emitting Diode) arrangement through LED package character analysis, LED module, and the characteristic of device were considered for uniform color mixing. A distance changeable optical device was built to assure high uniformity and high diffusion of not only the middle of diffusion side but also the border side. Also, we developed the control power circuit that can expand up to 6 channels which are possible for quantitative color mixing, and the high uniformity and high quantified border light for color mixing control and the verification of color mixing characteristics by composing GUI(Graphical user interface) including color mixing simulator. By presenting the experimental results of light color control, we proved the usefulness of our developed border light and the proposed color mixing method.

본 논문에서는 효과적인 영상검색을 위한 특징으로 칼라 크로스-코렐로그램(color cross-correlogram)을 제안한다. 칼라 크로스-코렐로그램은 영상에서 일정 거리에 있는 두 화소에서 다른 칼라가 나타날 확률을 나타낸 것으로, 영상에 존재하는 하나의 칼라를 가지는 영역의 크기 정보를 포함하지 않는다 그래서 영상에 존재하는 영역의 크기 변화에 대해 강인하게 영상을 검색할 수 있다. 실험을 통해 제안한 방법은 영상의 물체 크기 변화에 강인하게 영상을 검색할 수 있음을 확인하였고, 칼라 코렐로그램을 이용한 검색보다 우수한 성능을 나타냄을 확인하였다.
