  • In this paper, we present an effective viewpoint estimation algorithm for the Moving parallax barrier method of 3D display mobile device. Moving parallax barrier is designed to overcome the biggest problem, the limited view angle. To accomplish it, the position of the viewer's eyes or face should be estimated with strong stability and no latency. We focus on these requirements in the poor performance of mobile processors. We used a pre-processing algorithm in order to overcome the various illumination changes. And, we combined the conventional Viola-Jones face detection method and Optical-flow algorithm for robust and stable viewpoint estimation. Various computer simulations prove the effectiveness of the proposed method.

  • For bringing about a revolution in studying the classic literature the positivism must be overcome and the imaginative power about the history, literature and religion must be exercised. The theme of the monk-mask-play had been interpreted from the both viewpoint; the traditional mask play is the profane drama, but, on the other hand, it is the sacred drama. Judging from the social viewpoint, the sexual union of the old monk and the beauty symbolizes the reconciliation between the governing class and the production class. Judging from the viewpoint of the equalitarianism, that symbolizes the harmony of a masculinity and a femininity. Judging from the viewpoint of the education, that symbolizes the unification of reason and sensitivity. Judging from the viewpoint of the religion, that means the resurrection.

  • The purpose of this study is to suggest standard bodytype which offers criterion for the sizes and shapes to interpret various bodytypes, to estimate fitting, and to construct ready-made clothing. There were two ways of analyzing bodytypes of subjects from the viewpoint of statistic and beauty. We had carried on the analysis from the viewpoint of statistic in the Part(1) and we carried on the analysis from the viewpoint of beauty in this Part(2). Taken as a sample, the subjects were ninety-seven females who were between the aloes of 18 and 24 rears o1d. They were measured on November 1999. The data of seven hundred and four females,18∼24 year-old, from the National Somatometry Survey of 1997 were used for analysis, too. The first analysis from the viewpoint of beauty was executed to the front and side photographs of the subjects to analyze the general traits of the beautiful bodytype. The second analysis from the viewpoint of beauty was executed to subjects who were in both High-frequency proportion range and Beautiful bodytype group. As the result, four groups in Beautiful and High-frequency proportion range were selected. The standard proportion was analyzed with the size and shape of four groups. Based on the standard proportion, the size, shape and silhouette of the standard bodytype were analyzed. To verify the size, shape and silhouette of the standard bodytype, the location of the standard bodytype in the 1997 National Somatometry Survey group was analyzed. As the result, the standard bodytype was verified as proper criterion to interpret various bodytypes, to estimate fitting, and to construct ready-made clothing.

  • 본 연구에서는 다양한 장르를 가진 디지털 게임의 영역에서도 1인칭 시점에 머물러있는 가상현실 게임 콘텐츠들의 한계에 대해 선행연구와 사례를 통해 고찰하고, 이를 바탕으로 가상공간 게임에서의 시점(1인칭, 3인칭)과 햅틱 피드백이 가져다주는 게임의 몰입감과 현존감 및 재미의 차이를 실험을 통하여 알아보았다. 실험 결과를 살펴보면 게임의 시점은 3인칭일 때보다 1인칭일 때, 햅틱 피드백이 제시될 때 몰입감과 현존감 및 재미가 증가하는 것을 알 수 있었다. 그러나 가상공간 환경과 게임 시점 간의 상호작용은 발견할 수 없었다. 이러한 결과로 가상공간 게임들은 1인칭을 시점으로 하여 햅틱 피드백을 사용하는 것이 적절하다고 할 수 있으나 게임 시점과 가상현실 환경이 무관한 점, 1인칭시점 게임보다는 3인칭이 더 인기를 끄는 점 등 을 빌어 가상공간에서의 3인칭시점 게임의 가능성을 시사한다.

  • The modeling of business processes is key component of any improvement or re-engineering endeavor. Present trends of business modeling methodologies are to include the social context of an organization. Although various methodologies have been developed specially for the business process field and have a social context, it is not in terms of goals and customers, but processes, activities, and tasks. We describe our stance on business process modeling, based on the viewpoint of goal and customer. First, we formalize a goal-oriented business process model and its evaluation mechanism. Second, we propose a methodology of business process modeling, which starts from perceiving and describing interactions between organization and customer from the customer's viewpoint.

  • Housing distribution rate in our country has been continuously increased with economic growth, but residential plans satisfying the demands of residents are still not perfect yet. The demands of residents can be predicted by analyzing the housing viewpoint of residents. And also, the housing viewpoint can change according to various environmental changes, so it's important for us to understand the trend of change. Therefore, the housing viewpoints of university students who will be subjective residents of houses in future were analyzed by observing change due to trend of time. Target for this study is female university students in 20s. A portion of previously presented material (Korean Home Economics Association 37,1, 67-78) was used as data for 1998 and a questionnaire with 171 female university students was conducted on December 2008 for data for 2008. The following result was drawn from examination of change in the housing viewpoint due to trend of time by comparing the housing viewpoint of university students between 1998 and 2008. First, importance of was decreased and importance of was increased in functions of residence. Second, Most students thought and regardless of the time passage as their opinions on housing. And also, most students considered a living room as the most important space inside of a house regardless of the time passage and the ratio of considering a living room as the most important space was more increased.

  • Free viewpoint video (FVV) service is an immersive media service that allows a user to watch it from a desired location or viewpoint. It is composed of various forms according to the direction of the viewpoint of the provided video, and includes zoom in/out in the service. As consumers' demand for active watching is increasing, the importance of FVV services is expected to grow gradually. However, additional considerations are needed to seamlessly stream FVV service. FVV includes a plurality of videos, video changes may occur frequently due to movement of the viewpoint. Frequent occurrence of video switching or re-request another video can cause service delay and it also can lower user's quality of service (QoS). In this case, we assumed that if a video showing an object that the user wants to watch is selected and provided, it is highly likely to meet the needs of the viewer. In particular, it is important to provide an object-oriented FVV service when zooming in. When video zooming in in the usual way, it cannot be guaranteed to zoom in around the object. Zoom function does not consider about video viewing. It only considers the viewing screen size and it crop the video view as fixed screen location. To solve this problem, we propose a zoom in/out method of object-centered dynamic adaptive streaming of FVV in this paper. Through the method proposed in this paper, users can enjoy the optimal video service because they are provided with the desired object-based video.
