  • 교육 매개체의 디지털화를 위해 정보 통신망과 기술을 본격적으로 교육에 도입함으로써 교육의 패러다임이 e-learning(electronics learning)으로 이동하고 있다. 그러나 e-learning 콘텐츠는 컴퓨터가 있는 장소에서만 제공받을 수 있기 때문에, 언제 어디서나 사용자가 원할 때 교육받기 힘든 단점이 있으며, 기존 오프라인 콘텐츠를 e-learning 콘텐츠로 재구성하기 위해 많은 비용과 시간이 소요된다. 본 논문에서는 정적인 2차원 시각 정보만을 제공하는 기존 오프라인 콘텐츠의 그림 영상에 모바일 기기를 이용하여 동적인 인터랙션과 다양한 멀티미디어 정보를 융합할 수 있는 교육용 모바일 콘텐츠 (education mobile contents: EMC) 시스템을 제안한다. 제안된 영어 교육 콘텐츠는 기존 오프라인 콘텐츠의 그림 영상을 저해상도 카메라가 장착된 모바일 기기로 인식하기 위해 모양 기반의 영상 검색 방법을 이용하며, 수행속도와 크기와 기울기 변화에 강건한 시작점 일치를 통한 차분 체인코드 (differential chain code)를 사용한 DTW(dynamic time warping)를 이용한다. EMC는 모바일 기기를 이용하여 장소에 상관없이 오프라인 콘텐츠에 적합한 온라인 콘텐츠를 빠르고 정확하게 제공할 수 있다.

  • 카메라의 시선 방향에 따라 다른 영상을 생성하는 3차원 물체를 2차원 영상만으로 인식하는 것은 어려운 일이다. 특히 영상 생성 시 강한 투영변환(perspective transformation) 이 발생할 경우 투영된 물체의 이미지에 대한 국소 특징을 정의하는 SIFT(Scale-Invariant Feature Transform) 알고리즘은 물체 인식에 한계가 있다. 본 논문에서는 3차원 물체를 하나의 특정 축을 중심으로 회전시키면서 얻은 복수의 영상을 학습 데이터로 활용한 물체인식 방법을 제안한다. 이 방법을 이용하여 복수 영상의 특징 점들을 하나의 특징 공간으로 합성하고 영상들 간의 기하학적인 관계를 이용하여 중복된 영역을 제거한 모델을 생성하면 임의의 3차원 회전이 적용된 물체를 인식할 수 있다. 실험에서는 알고리즘의 유용성을 먼저 확인하기 위해 조명조건과 카메라의 위치를 일정하게 유지하였다. 이 방법에 의해 SIFT 알고리즘만으로 인식이 힘들었던 3차원 물체의 다양한 외관(appearance) 인식이 가능하게 되었다.

  • Operation and Maintenance (O&M) phase is the main contributor to the total lifecycle cost of a building. Previous studies have described that Building Information Models (BIM), if available with detailed asset information and their properties, can enable rapid troubleshooting and execution of O&M tasks by providing the required information of the facility. Despite the potential benefits, there is still rarely BIM with Mechanical, Electrical and Plumbing (MEP) assets and properties that are available for O&M. BIM is usually not in possession for existing buildings and generating BIM manually is a time-consuming process. Hence, there is a need for an automated approach that can reconstruct the MEP systems in BIM. Previous studies investigated automatic reconstruction of BIM using architectural drawings, structural drawings, or the combination with photos. But most of the previous studies are limited to reconstruct the architectural and structural components. Note that mechanical components in the building typically require more frequent maintenance than architectural or structural components. However, the building mechanical drawings are relatively more complex due to various type of symbols that are used to represent the mechanical systems. In order to address this challenge, this paper proposed a symbol recognition framework that can automatically recognize the different type of symbols in the building mechanical drawings. This study applied vector-based computer vision techniques to recognize the symbols and their properties (e.g., location, type, etc.) in two vector-based input documents: 2D drawings and the symbol description document. The framework not only enables recognizing and locating the mechanical component of interest for BIM reconstruction purpose but opens the possibility of merging the updated information into the current BIM in the future reducing the time of repeated manual creation of BIM after every renovation project.

  • Green Marketing, a response to the serious environment problems of the 21st century, is an important point for trends in both art and fashion. It is a strategy for reminding consumers of the threatening environment problems and to recognize that everyone must take responsibility for these problems. Green marketing is a concept that is the point at issue and social reform movement. The purpose of this study was to find examples of Green Marketing in fashion and classify them into four groups. The results of this study were as follows. First, the terms related to green marketing as related to fashion can be categorized into four areas: 1. Eco-friendly product marketing: product merchandising that usually uses organic materials and green manufacturing processes. 2. Green-communication marketing: PR strategies that use green slogans through deep impression advertising or special promotional events relating reducing, reusing and recycling, etc., with the brand's name. 3. Green environmental-marketing: marketing strategies that is an enlightenment campaign for environmental preservation and sustainable fashion design such as reusing, recycling, and reducing. 4. Cause-related marketing: marketing plans that return profits to society and that take an active part in the causes of the community. It was expected that these types of green marketing strategies would yield positive effects in enhancing brand value and consumer confidence as well as increasing profits.

  • This study aimed to provide data for establishment of resource management system of Iriomote Island in Okinawa Japan. Nature resource management system of Iriomote Island can be categorized into eight stages which are equivalent to regional development stages. 1) Networking among local people, tourists, researchers, tour operators and government authorities enhanced collection of resource data. 2) On the early stage, resource data were available only to researchers and government authorities. From the third stage of this system, however, local people were also involved in resource investigation, so they became to well recognize the values of their local resources. 3) On the sixth stage, data on unfamiliar local resources and attractions became to be known to people by real-time data collection and data provision services. The tourist number gradually increased and their visitation patterns were dispersed into different sites and seasons. In addition, some tourists also participated in resource investigation and they were likely to visit the place again. 4) To achieve successful ecotourism development, it is necessary to establish a management system with a feed-back process to identify, evaluate, use and protect the resources.

  • This study analyzed some of nursing homes in various domestic and foreign regions in order to find solutions to reduce suicidal incidents from the loneliness. To analyze community space of nursing homes, elderly community is analyzed into three categories based on their characteristics (morphological characteristics, Social characteristics, Environmental characteristics). With those three characteristics above, architectural spaces are analyzed the relation with them. Elderly nursing homes are divided with living, nursing, management, and public spaces. The space of elderly nursing homes (classification of function)-elderly community (classification of elderly characteristics) is approached in an architectural way related to the space of elderly nursing homes and elderly characteristics. Through some case studies, specific space relation of elderly nursing homes and elderly community is analyzed. Also, with the building analysis for summary, plans, wards(hospital rooms), cafeteria, program rooms and alley, some of general information and elderly community space is understood. In this study, there will be an analysis of relation of elderly community(morphological, social, environmental characteristics) which is separated into some spaces of elderly nursing homes(living, nursing, public spaces and facilities) written above. Furthermore, if people can recognize the importance of community space for elderly facilities, there will be a new guide line for that which can have a play on catalyst.

  • This paper suggests a method of detecting traffic lights for vehicles by combining the HSV(hue saturation value) color model, morphometric characteristics, and location information appearing on consecutive images in daytime. In order to detect the traffic light, the color corresponding to the signal lights should be explored. It is difficult to detect traffic lights among colors of lights from buildings, taillight of cars, leaves, placards, etc. The proposed algorithm searches for the traffic lights from many candidates using morphometric characteristics and location information in consecutive images. The recognition process is divided into three steps. The first step is to detect candidates after converting RGB channel into HSV color model. The second step is to extract the boundaries between the housing of traffic lights and background by exploiting the assumption that the housing has lower brightness than the surrounding background. The last step is to recognize the signal light after eliminating the false candidates using morphometric characteristics and location information appearing on consecutive images. This paper demonstrates successful detection results of traffic lights from various images captured on the city roads.

  • The detection of skin pigment is crucial in the diagnosis of skin diseases and in the evaluation of medical cosmetics and hairdressing. Accuracy in the detection is a basis for the prompt cure of skin diseases. This study presents a method to recognize and measure human skin pigment using Hemoglobin-Melanin (HM) coordinate. The proposed method extracts the skin area through a Gaussian skin-color model estimated from statistical analysis and decomposes the skin area into two pigments of hemoglobin and melanin using an Independent Component Analysis (ICA) algorithm. Then, we divide the two-dimensional (2D) HM coordinate into rectangular bins and compute the location histograms of hemoglobin and melanin for all the bins. We label the skin pigment of hemoglobin, melanin, and normal skin on all bins according to the Bayesian classifier. These bin-based HM projective histograms can quantify the skin pigment and compute the standard deviation on the total quantification of skin pigments surrounding normal skin. We tested our scheme using images taken under different illumination conditions. Several cosmetic coverings were used to test the performance of the proposed method. The experimental results show that the proposed method can detect skin pigments with more accuracy and evaluate cosmetic covering effects more effectively than conventional methods.
