We propose a method that classifies images into two object types man-made and natural objects. A central object is extracted from each image by using central object extraction method[1] before classification. A central object in an images defined as a set of regions that lies around center of the image and has significant color distribution against its surrounding. We define three measures to classify the object images. The first measure is energy of edge direction histogram. The energy is calculated based on the direction of only non-circular edges. The second measure is an energy difference along directions in Gabor filter dictionary. Maximum and minimum energy along directions in Gabor filter dictionary are selected and the energy difference is computed as the ratio of the maximum to the minimum value. The last one is a shape of an object, which is also represented by Gabor filter dictionary. Gabor filter dictionary for the shape of an object differs from the one for the texture in an object in which the former is computed from a binarized object image. Each measure is combined by using majority rule tin which decisions are made by the majority. A test with 600 images shows a classification accuracy of 86%.

Recently, rising of the convergence of technologies such as IT, GIS, GPS, and Sensors is developing the new information environment which enables man-to-man, man-to-object and object-to-object to exchange information anywhere and anytime. The Korean government has made great efforts to implement the virtual government with development of the next generation technologies continually and dynamically. These efforts for implementing e-government can be summarized by the citizen centered, integrated services, the customized personalization, the intellectual services, and the integration and cooperation between each offices for providing those services. Therefore, we wish to present the model of wide-area intelligent information systems which can provide services to form the future of this virtual government with GIS infrastructure in this study.

A prototype computer program was developed which visualizes various kinds of geotechnical information using 3D object graphics techniques. The program integrates various kinds of geotechnical data such as surface geology map, boreholes data, geophysical data as well as man made subsurface structures. It also reads NGIS DXF map and generates digital elevation model from iso-elevation line layer of the DXF map. All the data are put into a 3D model as 3D objects. The created 3D model can be viewed and analysed in a interactive 3D way.

In this paper the advanced method of geodesic active contours was developed for the task of building detection from aerial and satellite images. Automatic extraction of man-made structures including buildings, building blocks or roads from remote sensing data is useful for land use mapping, scene understanding, robotic navigation, image retrieval, surveillance, emergency management procedures, cadastral etc. A level set method based on a region-driven segmentation model was implemented with which building boundaries were detected, through this curve propagation technique. The essence of this approach is to optimize the position and the geometric form of the curve by measuring information along that curve, and within the regions that compose the image partition. To this end, one can consider uniform intensities inside objects and the background. Thus, given an initial position of the curve, one can determine global, region-driven functions and provide a statistical description of the inside and outside object area. The calculus of variations and a gradient descent method was used to optimize the variational functional by an iterative steady state process. Experimental results demonstrate the potential of the proposed processing scheme.

Fashion designs reflect the trend of the times embedded within the cultural structures of eastern and western civilizations as well as the traditional styles. However, the motives in fashion designs fundamentally come from human beings' willingness for creation through deep understand of nature or using symbolism and artificial esthetic appreciation. Mankind has expressed their willingness for creation through speculation not with the attitude of conquering nature but by acknowledging the flow between their lives and nature. The purpose of this paper is to investigate human beings' transcendental and embracing attitude toward the natural environment and the human environment in fashion design. In natural environment factors, sublimity toward nature's marvelous powers and the transcending state of mind within happiness and delight or the extreme fear or unavoidable coerciveness and the consequential daunting feelings and smallness, and sorrow all stimulate the will of mental speculation and cause a transcending sublimity. A sublime state of mind does not exist in a superficial framework of enjoyment. It is rather an act of transcendence and embracement residing in a sublime object and leading man's spirit into a state of philosophical thought. Also, in man-made Environment factors, we found from magnanimity we were ability to see the true nature of an era's culture.

Walter Gropius, famous architect of Bauhaus, once treated of pure mind which was revealed in the system of object and its phenomena through sense of sight while examining material being and illusive being. And Thomas Aquinas said that man can have a creative power only with modest mental state void of prejudice saying that he expected God to come to him after his soul went out of him. The same thing was said by so many great philosophers and thinkers other than him. I think his saying, "God comes after Soul's escape from the body for a new creation", has a real truth for all times and places and beauty itself beyond expression. Why\ulcorner The reason why the saying is so true is because it has a Yin and Yang Idea, that is, the Soul means a dark spirit correspondent to Yin between both oriental ideas and God does a bright spirit correspondent to Yang between them. By reason of this idea, I would like to assert that we should take it granted that we stand in need of the same bright Yang's spirit as God has for the new creation, and let the Yang's bright spirit come to our minds. We can call it divine 'Providence', or call it God's guidance, which we cannot help accepting as a man's fatality. As God was pleased after he made man and all the creatures by dint of his design, so man was pleased after he made everything he needed by the same design that he accepted from God. In spite of pleasure of different dimensions from what God and Man has each other, their way of empathies were all the same. In this paper I compared a worldly lower conception by which man designed his products for his sensuous satisfaction with a higher conception by which God designed his creatures for his mental satisfaction. I intended to infer what destined relation there must be between both God's and man's creations, trying to remind designers that they have to confess to have not so divine a providence as God has for creation because I think the real truth is that they had regarded their works of product design as a routine occurrence for their physical convenience in the industrial plans.ial plans.

영상 분류는 내용기반 영상검색에서 부적절한 이미지를 효과적으로 걸러 낼 수 있게 하여 영상 검색의 성능을 향상 시키는데 큰 역할을 하게 된다. 따라서 최근 의미 있는 영상의 분류가 내용기반검색분야에서 중요한 과제로 대두되고 있다. 본 논문에서는 에지 정보를 이용해서 객체 영상을 인공객체영상과 자연객체영상으로 분류하는 방법을 제안한다. 직선형태의 에지를 많이 가지는 인공객체의 경우 에지 방향 히스토그램의 에너지가 자연객체에 비해 높은 값을 가지기 때문에 객체 분류에 유용한 정보로서 에지 정보를 활용하였다. 또한 에너지 값을 낮추는 원형의 에지가 인공객체영상에서 주로 발견되는 점을 이용하여, 제거에 의해 분류의 성능을 높이고자 하였다. 한편 가버 필터를 이용한 분류 결과에 비해 에지 정보를 이용한 분류가 성능 면에서 보다 나은 결과를 얻을 수 있었다.

Spatially referenced mobile mapping (MM) images contain rich information of man-made objects , e.g. road centerlines, buildings, light poles, traffic signs ,billboards and line trees etc. Therefore, the applications in transportation, urban 3D reconstruction, utility management are implemented increasingly. It’s a fundamental issue lies in MM image process that how to orient this image in the object space including interior orientation of camera and the exterior orientation of image. In this paper, the algorithm of automatic acquirement of DC (Digital Camera) parameters based on MM images is illustrated. And then, the mapping between image space and object space for MM images is described.

Recently, we have reconstructed LX-200 12inch telescope system for tracking and observing man-made space object. Motor, motor driver and motion controller were up-graded for getting faster respond characteristic and active control available. Also, command signal was offered to the PID controller into motor driver as computed real orbiting information of objects using PC, and it's control period of command signal was reduced to the 20ms. As the result, slew speed of the mount system was in proved up to $18^{\circ}/sec$ and respond speed of the system was faster than that of commercial system. Also, flipping state of image observed could be minimized by the up-graded system.

This study discusses the beauty of the ideal body shown by fashion communication media, and explains how aesthetic aspects of, the body are being expressed in contemporary fashion. The beauty of the body may be considered as the beauty of sexual, controllable or consumable object. First. the most vigorously discussed point about the body is its sexual aspect, the most outstanding of which is the voluptuous and the androgynous beauty in contemporary fashion. Second, the body is an object which has been oppressed or controlled under the name of history. morality. and rationality. The things making us regard the body itself as an aesthetic object may be considered as dynamic and functional beauty Third, the sexual instinct and the body are fetishized as consumer goods, and women's bodies are presented as comsumer objects whose most parts could be restored to exchangeable value. The consumable beauty presented in contemporary fashion is the conspicuous beauty and the decadent beauty. So far, the various aspects of the beautiful body has been considered, based on the beauty of the ideal body shown by the fashion communication media. Man exists through on his body. but it is the embodied and formed body that serves as a means to manifest his social status and cultural ties. A natural body is reformed as a cultural phenomenon in various artificial ways. Popular culture has transmitted a series of new body image by creating and reproducing symbols and images, and has made the ideal body. Now there is not only one standard for the ideal beauty in our society. The standard of the beauty has changed continuously. There has been an aesthetic sense which can represent the times during the process of those changes. The various communication media have played a role of mirror reflecting those changes. The ideal body in contemporary times is no more an abstract media to express classical beauty, but an object directly affecting us, who are living in the crisis of subjectivity and identity.
