It is difficult to figure out the specific contents of the buildings in the internet spatial area, since those data on the internet present only the location of buildings and the outlines of lands on which buildings are located, An experimental study for the view management of building information at internet urban spatial area was conducted on the Web-GIS based map using hyper map. With the building information on the 2-D map, modified from the previous numerical map and the regional building information and additional information, a new form of building through 3-D icons was shown on the internet spatial area. This study shows the Web-based building management system, which is designed to manage attribute data about hyper-linked buildings of 2.5-D icons and to reproduce visual building information by putting a variety of information into hyper-linked icons on the hyper map. This system not only complements the lack of consistency between real buildings and those on the map, but also provides users with more familiar urban space, so that everybody can utilize the building information as long as he has access to the internet.

In this paper we propose a fast adaptive image restoration filter using DCT-based block classification for reducing block artifacts in compressed images. In order to efficiently reduce block artifacts, edge direction of each block is classified by using the DCT coefficients, and the constrained least square (CLS) on the observation that the quantization operation in a series of coding process is a nonlinear and many-to-one mapping operator. And then we propose an approximated version of constrained optimization technique as a restoration process for removing the nonlinear and space-varying degradation operator. For real-time implementation, the proposed restoration filter can be realized in the form of a truncated FIR filter, which is suitable for postprocessing reconstructed images in HDTV, DVD, or video conference systems.

The purpose of this study was to analyze the characteristics of the Junk Art represented in the second half 20the century fashion. The highly developed material civilization resulted in human alienations environmental distruption. By this fact human being of the 20the century was to overcome social com-plexity. In this respect this research was focused that how the characteristics of the junk Art was expressed in the second half 20th century fashion. The concepts of the Junk Art lied in the creation of art work in the 2-dimentional plane of 3-dimentional space through the application of all junks (wood pieces industrial debris trash ready-made goods etc) cast by the mod-ern industrial society and the mass production system. Juck Art had been further envigorated in the footstep of the development of the collage method based on the creation of object aes-thetics. And junk artists have untitled social environments with art by assembling junks as a way of exploring the material world of cur-rent society and provided infinite possibilities of expressional medium and technique. Above all junk Art has been reflected in the fashion as well as other art. Especially a lot of the fashion design by the use of junks and the expressive image of junks is produced in the 20th century. That is many of fashion designers have always been aware of what is happening in the arts and have always been able to use the dis-coveries and ideas of the artist to help them solve design problems and creat fashion which are new inventive and reflective of their time. The fashion designers of the junk fashion design could be said to have presented much more possibilities and new development for-mulas to modern fashion design and provided a new order of other formative arts. Unlike the negative and destructive punk cyberpunk fashion junk fashion was a positive and optimistic aesthetics. junk fashion that keeps pace with science and the development of technology is devoted to trying to grasp the real form of ultimate re-ality.

Three-dimensional image reconstruction allows us to represent real objects in the virtual space and observe the objects at arbitrary view points. This technique can be used in various application areas such as education, culture, and art. In this paper, we propose an implementation method of the high-quality three-dimensional object using multiple Kinect cameras released from Microsoft. First, We acquire color and depth images from triple Kinect cameras; Kinect cameras are placed in front of the object as a convergence form. Because original depth image includes some areas where have no depth values, we employ joint bilateral filter to refine these areas. In addition to the depth image problem, there is an color mismatch problem in color images of multiview system. In order to solve it, we exploit an color correction method using three-dimensional geometry. Through the experimental results, we found that three-dimensional object which is used the proposed method is more naturally represented than the original three-dimensional object in terms of the color and shape.

The objectives of this study are to develop a state-space form of stochastic dynamic storage function routing model and to test the model performance for real-time flow forecast. The selected study area is the main Han River starting from Paldang Dam site to Indogyo station and the 13 flood events occurred from 1987 to 1998 are selected for computing model parameters and testing the model performance. It was shown that the optimal model parameters are quite different depending on Hood events, but the values used on field work also give reasonable results in this study area. It is also obvious that the model performance from the stochastic-dynamic model developed in this study gives more accurate and reliable results than that from the existing deterministic model. Analysis for allowable forecast lead time leads that under the current time step the reasonable predicted downstream flows in 5 hours time advance are obtained from the stochastic dynamic model on relatively less lateral inflow event in the study area.

Head-Up Display, an information-providing display, is a device that provides necessary information through a vehicle window for a driver when driving, with which the driver secures the visibility and acquires information necessary for driving. Head-up displays in early days were mostly installed in imported vehicles but increasingly, being installed in medium and large-sized domestic vehicles, they secures convenience of driving and information acquirement. The information display element of each of currently released brand cars not only has limits in consistency and in displaying interface but also reveals the limitation of a way to apply GUI, being applied to dot reflective form in terms of the technology type. Accordingly, this study draws real time information element described as necessary during driving through case survey and analysis, and aims to provide a user with new GUI guideline through transparent display technology recently developed based on results analyzed with priority of POI(Point of Interest) information.

This paper proposes a lane departure detection algorithm using a single camera equipped in front of a vehicle. The proposed algorithm generates a partial top-view image for a small ROI (region of interest) designated on the top-view space form the image acquired by the camera, detects lanes on the small partial top-view image, and makes a decision on the lane departure by checking overlap between the pre-assigned virtual vehicle and the detected lanes. The proposed algorithm also includes the removal of lines occurred by road symbols (noises) disturbing the lane departure detection between lanes and the prediction of lost lanes using lane information of previous fames. In lane departure detection test using real road videos, the proposed algorithm makes the right decision of 99.0% in lane keeping conditions and 94.7% in lane departure conditions.

The modular robot is one which was developed to get over limit of the space movement for the mobile robot. The chain type robot in particular is connected by series each other and this form expression method is simple and easy to really make a docking method efficiently. However, the related studies were focused on the movement that used to be combination, and the movement of a cell independent mainly does not consist and have a problem to dock only in a direction, not to be connected with all directions. Therefore, we suggested a modular structure for quick, independent movement to solve such a problem and had own autonomy. In addition, we are intended to get some effectiveness for connection mechanism using one locking motor. In this paper, we dealt with the design for the mechanical and electrical points and docking algorithm including communication method. All of the structure is verified with real action experiment through the shape expressions of various application platform.
