This paper proposes an efficient method of object identification and localization for image recognition. The new proposed algorithm utilizes correlogram back-projection in the YCbCr chromaticity components to handle the problem of sub-region querying. Utilizing similar spatial color information enables users to detect and locate primary location and candidate regions accurately, without the need for additional information about the number of objects. Comparing this proposed algorithm to existing methods, experimental results show that improvement of 21% was observed. These results reveal that color correlogram is markedly more effective than color histogram for this task. Main contribution of this paper is that a different way of treating color spaces and a histogram measure, which involves information on spatial color, are applied in object localization. This approach opens up new opportunities for object detection for the use in the area of interactive image and 2-D based augmented reality.

Since Korea has already become the 'aging society' and is expected to become the 'aged society' by 2019, development of the facilities and dedicated housing for the senior citizens have become the key issues. The growing population of the senior citizens, changed in the social structure, family type, and the way of living brings a moment to consider the various aspects to support the senior citizens. Now the situation in Korea requires development of congregate housing as a type of residential units for elder who can live at home with some help. Therefore, the purpose of this research was to analyze preference tendency on the interior finishing materials and colors of the congregate housing for the senior citizens who are healthy enough not needing the nursing home. For this research, the preference of 500 Korean pre-senior citizens on the interior finishing materials and colors of congregate housing for the seniors was investigated. The collected data was processed using SPSS 10.0 for Windows regarding frequency, percentage, average, Chi-squared test with cross tabulation. The results are as follows: First, about $60\%$ of the respondents preferred Korean traditional interior image for individual units, and modern interior image for common areas. Second, the respondents preferred wood flooring and wallpaper interior finishing. Third, the respondents Preferred Y, YR color for individual units, and N color for common areas and very pale tone for all spaces. Fourth, the respondents preferred luxury finishing to living room in the all spaces.

The Sign system of nursing home plays an important role when an elderly adapts to new environment and gets on daily life autonomously. Common living spaces are expecially important in maintaining social nature, adequate signage should be installed to aid them in finding their ways. Sign system is a comprehensive system consisted of various factors. In this research, it has been categorized as signage and cueing. Signage includes text and graphic signs, and cueing consists of floor plan configuration and sensual mechanism of visual, auditory, olfactory senses. Using this framework, held investigation and analysis were held in common area(shared living room, shared dining room, toilet) of 14 Korean, 8 Northern European, and 10 Japanese nursing home facilities. The result revealed that even though sign system should work as a combined unit, each factor was planed without relations to each other and did not perform mutually complementary role. Signage was installed too high, without considering the posture of elderly. Korean facilities used abundant and diverse signage compared to other countries. Japanese nursing home preferred cueing method over signage, and those of Northern Europe used plentiful visual cues such as color and ornaments.

The purpose of this study was to carry out POE of assisted living housing and suggest the design guidelines for the housing complex for the elderly. The subjects were residents(old persons) and staff who lived or worked in three assisted living housing in Cincinnati, Ohio. Interview and survey method using questionnaire were used. The design guidelines for the housing for the elderly were suggested as follows: 1) the location of the housing for the elderly should be in or near the existing housing area, 2) the arrangement of spaces of the housing for the elderly should consist of small groupings rather than large and long corridor pattern, 3) the number of the housing units for the elderly should be small, under 100 units, 4) the housing units should be used by one older persons so that she/he could have the chance of privacy and personalization, 5) various common spaces such as art and craft room or game room should be provided, 6) accessibility should be considered, 7) the color and patterns of interior finishes should be differentiated according to floors or spaces and familiar ones should be used to make a homelike environment.

The purpose of this study is to suggest the specific design guidelines for major physical elements like colors, patterns or shapes which can produce the place identity enhancing wayfinding affordability. The research consists with theoretical studies. From the precedent researches, the main design principles enhancing wayfinding affordability were defined and then the list and the nature of the major physical interior elements were drawn, based on them. The result presented that the specific design guidelines as well as design principles could be focused on the categories like generating landmarks, introducing color codes, floor patterns, and wall decorating. And dealing them to promote place identity, were shown as useful in articulating the pathway and indicating spatial orientation. Design guidelines as the result of the research, could be easily and directly applied on the real public spaces as a visual guidance enhancing navigability(the ability to recover position and orientation) to make up the wayfinding weakness.

본 논문에서는 사람의 식별과 감정을 인식하기 위한 새로운 방법을 제안한다. 제안된 방법은 색차 정보에 의한 형판의 위치 인식과 형판 벡터 추출에 기반 한다. 단일 색차 공간만을 이용할 경우 피부색 영역을 정확히 추출하기 힘들다. 이를 보완하기 위해서 여러 가지 색차 공간을 병행하여 피부색 영역을 추출하며, 이를 응용하여 각각의 형판을 추출하는 방법을 제안한다. 그리고, 사람의 식별과 감정 인식을 위해서 추출된 형판에 대한 각각의 특징 벡터를 신경회로망을 이용하여 학습하여 사용한다. 마지막으로, 제안된 방법은 실제 실험을 통하여 그 가능성을 보인다.

A new fastness formula based on the CIEDE2000 color-difference formula was developed by B. Rigg and his coworkers. It is much simpler to calculate the staining fastness grade than the ISO 105-A04 fastness formula based on the CIELAB color-difference formula. Sample pair sets, which cover a wide color space range were accumulated from the NCS(Natural Color System) color book. for those sample pair sets, a visual measurement experiment and an instrumental measurement experiment of fastness grade were carried out. Each performance of the ISO 105-A43 fastness formula and newly developed fastness formula was compared through degree of agreement for visual measurement results. The newly developed fastness formula indicated improved performance for measuring fastness grade as it was confirmed that the performance of the current ISO fastness formula ISO 105-A04 for assessing staining, was inadequate for measuring fastness grade. Then the fastness formulae were examined more closely according to the particular color spaces and the correlation of hue, lightness and chroma for measuring staining fastness grade was also considered to recommend more improved fastness formula. By modifying the weighting functions of CIEDE2000, which is a basis of new fastness formula developed by B. Rigg, a modified fastness formula is proposed in this study.

반응물과 생성물이 자외선 및 가시광선 영역에서 빛을 흡수하는 경우 시료의 농도 및 화학반응의 특성을 평가하는데 자외선가시광선분광법을 사용할 수 있다. 하지만 고농도와 높은 반응 온도 조건에서는 자외선가시광선분광법을 사용하는데 한계가 존재한다. 색을 가지고 있는 시료의 촉매 반응을 색상 분석으로 농도 및 조성을 외부에서 수집한 이미지를 분석하여 자외선가시광선분광법에서 동일한 결과를 얻을 수 있다. Resazurin은 촉매 및 환원제에 의해 resorufin으로 환원되며 농도에 따라 적색변광이 일어나며 카메라를 통해 수집하여 분석할 수 있다. 색상 분석을 위한 색공간은 CIE L^*a^*b^*를 사용하였고 소프트웨어를 통해 각각의 색상좌표 값을 추출하고 각 시료의 농도를 분석하였다. 시료의 농도와 촉매 반응에 대해 색공간을 이용한 분석법과 자외선가시광선분광법의 결과와 비교하여 제시된 방법의 유효성을 확인할 수 있다. 더욱이 색상 분석을 통한 농도 분석에서는 자외선가시광선분광법과 다르게 흡수파장이 중복이 있는 경우에도 디콘볼루션 없이 독립적으로 두 물질의 농도 측정이 가능하다.
