Various studies with regard to increasing the optical efficiency of plasmonic color filters have previously been conducted, such as mixing materials or applying diverse pattern shapes. Fundamentally, it is important to maximize the photonic crystal effect by finding the optimum periods of lattice as well as calculating the most efficient transmission area. In this study, we propose a technical method for optimizing the plasmonic color filters that have a high color gamut and luminance by analyzing the light spectrums based on the 1931 color coordinate system. Moreover, we suggest a calculation method in order to define the individual color purity of red and green and blue filters. Consequently, efficiency values are obtained independently from each color filter by evaluating the color purity and the luminance. The final result obtained from simulation are 27.6% of relative luminance and 25.3% of color gamut. The proposed optimization method is applicable to all plasmonic color filters having photonic crystal arrays.

A Radioactive constraint of the nuclear fuel assembly irradiated by neutron during normal operation cycle of the nuclear power plant is typically on the order of about 3 kGy/h. In order to inspect nuclear fuel assembly using a VT (vision technology) system, the light such as halogen lamp is used. As the halogen lamp has lower color temperature than the sun light, the objects under halogen lamp illumination are seemed to be tinted with red. In this paper, high brightness LED is considered to be used as the light source of VT system. The high brightness LED, which is a key light source of the VT system, have been gamma irradiated at the dose rate of 4 kGy/h during two hours up to a total dose of 8 kGy. The radiation induced color-center in the LED housing cap made of plastics materials is observed.

In this paper, we present a collaborative method for material delivery using a distributed vehicle agents system. Generally used AGV(Autonomous Guided Vehicle) systems in FA require extraordinary facilities like guidepaths and landmarks and have numerous limitations for application in different environments. Moreover in the case of controlling multi vehicles, the necessity for developing corporation abilities like loading and unloading materials between vehicles including different types is increasing nowadays for automation of material flow. Thus to compensate and improve the functions of AGV, it is important to endow vehicles with the intelligence to recognize environments and goods and to determine the goal point to approach. In this study we propose an interaction method between hetero-type vehicles and adaptive fuzzy logic controllers for sensor-based path planning methods and material identifying methods which recognizes color. For the purpose of carrying materials to the goal, simple color sensor is used instead vision system to search for material and recognize its color in order to determine the goal point to transfer it to. The proposed method reaveals a great deal of improvement on its performance.

According as the drivers increase who have their cars, the comprehensive studies on the automobile for the traffic safety have been raised as the important problems. Visual Recognition System for radio-controled driving is a part of the sensor processor of Unmanned Autonomous Vehicle System. When a driver drives his car on an unknown highway or general road, it produces a model from the successively inputted road traffic information. The suggested Recognition System of the Road Traffic Safety Information Board is to recognize and distinguish automatically a Road Traffic Safety Information Board as one of road traffic information. The whole processes of Recognition System of the Road Traffic Safety Information Board suggested in this study are as follows. We took the photographs of Road Traffic Safety Information Board with a digital camera in order to get an image and normalize bitmap image file with a size of $200{\times}200$ byte with Photo Shop 5.0. The existing True Color is made up the color data of sixteen million kinds. We changed it with 256 Color, because it has large capacity, and spend much time on calculating. We have practiced works of 30 times with erosion and dilation algorithm to remove unnecessary images. We drawing out original image with the Region Splitting Technique as a kind of segmentation. We made three kinds of grouping(Attention Information Board, Prohibit Information Board, and Introduction Information Board) by RYB( Red, Yellow, Blue) color segmentation. We minimized the image size of board, direction, and the influence of rounding. We also minimized the Influence according to position. and the brightness of light and darkness with Eigen Vector and Eigen Value. The data sampling this feature value appeared after building the learning Code Book Database. The suggested Recognition System of the Road Traffic Safety Information Board firstly distinguished three kinds of groups in the database of learning Code Book, and suggested in order to recognize after comparing and judging the board want to recognize within the same group with Nearest Neighborhood Decision Making.

The purpose of this pilot study was to examine the effect of tongue color change due to food ingestion on tongue diagnosis by both Korean Medicine doctors and digital tongue diagnosis system. In order to obtain objective and quantitative data, we used digital camera to collect the data. Prior to our investigation, we conducted a brief survey of 26 Korean Medicine doctors and found out that tongue diagnosis is frequently used and food-stained tongue could be commonly observed in clinics. Depending on their color, viscosity, and amount of intake, various foods caused stains with different colors and thicknesses. Also, duration and amount of food stain on tongue were different from person to person. Since coffee-stained tongue was the most frequently observed one in clinics according to the survey, we used coffee to evaluate the effect of food-stained tongue on tongue diagnosis. Korean Medicine doctors tended to interpret coffee-stained tongue as having yellow tongue coat but their judgement on tongue body color did not differ in spite of the coffee stains. Meanwhile, tongue diagnosis system algorithm tended to judge coffee-stained tongue as having normal but yellowish tongue coat and reddish tongue body. Altogether, food color on tongue can influence tongue diagnosis outcomes. Further research is needed in order to develop more efficient tongue diagnosis algorithm and digital medical service system.

문화유산의 현색(顯色)은 제작기법 해석, 보존처리 활용, 상태 모니터링의 중요한 기초 자료이다. 이 연구에서는 권응수 초상을 대상으로 디지털 색관리시스템 기반 색재현 과정을 체계적으로 정립하고, 문화유산 기록 및 보존에 적합한 현색 활용방안을 제안하였다. 전체적인 색재현 과정은 촬영 환경 세팅, 색기준차트 측정, 디지털 사진 촬영, 색보정, 색공간 설정 순으로 진행되었다. 연구 결과, 사진기 제조사 프로파일이 적용된 디지털 이미지는 현색과 비교하여 평균 𝜟10.1의 색차를 보인 반면, 디지털 색재현 이미지는 평균 𝜟1.1의 색차를 보여 현색과 거의 유사한 것을 알 수 있다. 이 결과는 디지털 사진 촬영 환경과 조건을 최적화했더라도 디지털 사진기 제조사의 보정 알고리즘에 의존할 경우 대상 문화유산의 현색 기록에 어려움이 있는 것을 의미한다. 따라서 문화유산은 RAW 이미지 기반의 색보정 및 색공간 설정을 통해 디지털 색재현이 필요하며, 이는 현색 기록화를 위해 매우 중요한 과정이다. 또한 디지털 색재현을 통한 현색 기록은 문화유산의 보존상태 평가와 보존처리 및 복원의 중요한 기초자료가 될 수 있으며, 퇴색 및 변색 현상의 모니터링을 위한 기준 데이터로 활용성이 높을 것으로 판단된다.

정보처리기술을 활용한 칼라 감성 시뮬레이션이 상품개발 지원시스템으로서 개발, 활용되기 시작하고 있다. 칼라배색 등을 결정하기 위한 시뮬레이션 시스템에서는 감성평가실험을 통해 구축한 데이터베이스를 이용하여 배색후보들을 제시하는 것이 일반적이다. 그러나 이들 방법에서는 시스템 이용자(디자이너나 사용자)의 취향이나 선호도, 혹은 이용자 상호간의 감성적차이(gap) 등을 고려하여 최종 배색후보를 결정해 가는 과정까지는 지원하고 있지 않다. 이와 같은 점에 주목하여 본 연구에서는 시스템이 초기 배색 후보군을 생성한 다음, 디자이너가 다양한 배색 시뮬레이션을 함으로써 목적으로 하는 최종 배색후보를 결정해 가는 과정을 지원하는 칼라배색시뮬레이터를 제안하였다. 이 시뮬레이터는 디자이너가 시스템과의 커뮤니케이션에 의해 디자이너의 취향과 선호도에 맞는 배색을 탐색할 뿐만 아니라 검색자가 최적이라고 판단하기 용이한 환경을 제공함으로써 시스템이 검색자의 판단을 지원하는 디자인지원시스템의 성격을 가진다. 칼라 배색시뮬레이터는 디자이너의 사고과정을 모델화 한 이중매핑 모델(Dual Mapping Model)에 기초로 두고 구성되었으며, 칼라컨셉설정$\longrightarrow$배색후보군 생성$\longrightarrow$배색 시뮬레이션$\longrightarrow$최종배색 후보의 순위결정 등의 4단계에 걸친 조작으로 칼라 디자인과정을 지원하게 된다.
