본 논문은 차량 영역에 나타나는 수평, 수직 에지 특성만을 이용하여 빠르고 효율적으로 차량을 검출하는 방법을 제안한다. 차량을 포함하는 입력영상의 긴 수직 에지 성분을 찾아 차량의 후보 영역을 결정한다. 영상의 에지 성분의 누적 대신 연속적으로 나타나는 긴 수직 에지 성분을 찾음으로써 차량의 후보 영역의 검출과 동시에 중요한 정보를 담고 있는 도로와 접하는 차량의 하단부를 함께 검출한다. 후보 영역 내에서 차량과 비 차량을 구분하는 검증 단계에서는 차량의 후면의 대칭성(Symmetry)을 이용하여 후보 영역 내에서 차량이 있을 가능성이 있는 바닥 점 위에서 좌측과 우측의 유사도(Matching rate)를 이용하여 차량과 비 차량을 판별한다. 기존의 템플릿 기반 방법이나 외관 기반 방법이 아닌 에지 성분만을 이용하여 후보 영역을 결정하고 검증하기 때문에 다른 검출 기법들에 비해 비교적 검출 시간이 짧고 실시간 차량 검출에 적합하다.

Due to recent climate change, flood damages have been increased, but it is difficult to construct large hydraulic structure for flood control such as dam because of environmental, economical and political problems. For this reason, several researches and studies have tried to use washland as an alternative of hydraulic facility. Because sizes of washlands are usually smaller than those of dams or reservoirs, there can be many available locations for washlands in a basin and proper combination of these locations can reduce flood disasters efficiently. However, in case there are many available locations for washland and many combinations to consider, it is very difficult to determine the optimal combination which yields to provide the maximum benefit. For the more, hydraulic approach that used in previous studies to calculate flood reduction effect needs a lot of time for calculation and sometimes can not give the final result. In this study, the flood reduction effect of washland is calculated by hydrologic approach and decision making model for optimal location of washland using genetic algorithm for determination of optimal solution is developed. The developed model has been applied to the Ansung River basin in order to examine the applicability and the application result shows that developed model can be used as decision making model for washland.

This study utilizes the meta-analysis for the benefits transfer (MA-BT) approach to measure social costs the 7 target sites in the City and County of Honolulu. The estimated MA models (MA-1 and MA-1) were evaluated in terms of validity and reliability criteria. This study utilized a parametric t-test and a non-parametric sign rank test for checking validity. A transfer error measured by an absolute percentage difference was utilized to check reliability their similarity. The GIS was utilized for data collection in order to measure social costs for each target site. The results clearly demonstrated that social costs were substantially higher thant direct costs and varied market conditions and different methods used. In terms of validity and reliability criteria, MA models were preferred to the mean transfer value approach. MA-BT approach is desirable for measuring social costs for a project designed to measure social costs for these 7 proposed landfill sites with inaccessible data, on short time frames, and with little money. If researchers and planners have enough time and money, they can implement primary research. If not, the meta-analysis for the benefits transfer approach can be much better than no framework. The use of a GIS can help to identify secondary data within a specific radius of each target site.

Most of a BIPVS (Building Integrated Photovoltaic System) is installed on the rooftop or wall of a building. Therefore, the main factor to consider for selecting the installation site is the shadow effects produced by the surrounding buildings. On the other hand, when the photovoltaic was installed on soundproof walls, shadow effects were produced by not only surrounding buildings but also the surrounding trees. Therefore, a different data model and algorithm with the BIPVS case are essential for proper installation sites selection of a SIPVS (Soundproof wall Integrated Photovoltaic System). This paper deals with the DSM (Digital Surface Model)-based proper installation site analysis for SIPVS. First, the solar incident and altitude angles of the installation candidate sites (solar panel) during the year were calculated. Second, the shadow effects (shadowed or unshadowed) were determined for the candidate sites at each time with the DSM. Third, the amount of solar radiation was calculated with the incident angle for the candidate sites at an unshadowed period. The proper installation site of the SIPVS could then be selected by comparing the accumulated annual solar radiation for each candidate. The proposed algorithm was implemented as a prototype (Java program). From the experiment, the order of the installation suitability was determined among the nine candidates. The proposed algorithm could be used for proper BIPVS installation site analysis aimed at the lower part of a building and calculation of the expected power production.

This study was started for providing the application method of hyperspectral im age over extreme cold area as the Antarctic. Study area was Terra Nova Bay area which was decided as the candidate of 2nd Antarctic base station. For deciding last location of base station, many researchers tried to analyze the suitability of this study area. Among many suitability indicators, the location and stability of extracted bed rock area were very important. Using many spectral information of hyperspectral data, we tried detecting of bed rock and classifying four rock types. As additionally data, international spectral library of rock were used in this study. At the results, short-infrared wavelength bands were useful in the detection and classification of bed rock.
