This paper analyzes metadata workflow from creation to browsing, and discusses metadata authoring and browsing technology. Unlike usual multimedia authoring, broadcast metadata authoring means metadata editing synchronized with video. In order to make practical application of other systems, the result is in XML or MXF(Material eXchange Format) based on common metadata scheme. The MXF Browser developed with the consideration of broadcast metadata that is time-synchronized with AV content provides not only metadata authoring capability but also advanced content browsing services such as summary playback and highlight browsing based on metadata multi-track.

In this paper we propose a Wavelet- based compression algorithm of HDTV video signals for the purpose of recording HDTV signals in the digital VTR. Comparing to the DCT- based compression method, which only yields unrecognizable DCT coefficients, the low frequency components of Wavelet coefficients maintain recognizable spatial domain information. So, it is more suitable for various VTR operations such as editing and multi-speed mode operations. Also, the adopted Wavelet filter can be Implemented with simple shift operations, which can reduce the computational complexities substantially. The quality of reconstructed HDTV signals with a 4:1 compression ratio turns out to be good enough for the studio use.

Feature detection is important in various mesh processing techniques, such as mesh editing, mesh morphing, mesh compression, and mesh signal processing. In this paper, we propose a geometric snake as an interactive tool for feature detection on a 3D triangular mesh. A geometric snake is an extension of an image snake, which is an active contour model that slithers from its initial position specified by the user to a nearby feature while minimizing an energy functional. To constrain the movement of a geometric snake onto the surface of a mesh, we use the parameterization of the surrounding region of a geometric snake. Although the definition of a feature may vary among applications, we use the normal changes of faces to detect features on a mesh.

This paper show that we analyze the mise en scene of animation based on the theory of mise en scene in film. The mise en scene of animation has a large range of utilization in contrast to film. This affects the development of film synthesized with an actuality film. The theory of mise en scene of early realistic film director is extended by the animation techniques. And the theory of mise en scene in digital film is raised newly. The mise en scene in animation has the property that ail elements Is represented in one frame. And then this has a success in different aesthetics. The problems of in-country animation - the absence of production in the present condition - is to be achieved by the production using mise en scene.

It is very important to generate a simplified model from a complex 3D character in computer game. We propose a new method of extracting feature lines from a 3D game character. Given an unstructured 3D character model containing texture information, we use model feature map (MFM), which is a 2D map that abstracts the variation of texture and curvature in the 3D character model. The MFM is created from both a texture map and a curvature map, which are produced separately by edge-detection to locate line features. The MFM can be edited interactively using standard image-processing tools. We demonstrate the technique on several data sets, including, but not limited to facial character.

The importance of design is emphasized in many industries. It began to earn recognition as part of industry rather than the arts. In particular, utilization of visual information design including moving images, packaging, advertisement, publication, editorial and visual information processing is higher than others in the design field. However, disputes relating to intellectual property rights have been also increasing as it became known. Therefore, now is the time to consider and establish an effective dispute settlement system for the design industry. In this view, arbitration will be a suitable method for dispute settlement in visual information design because of characteristics such as confidentiality, professionalism, efficiency, economy and flexibility. However, Arbitration system is not well known to the people who work in this industry. Thus, in order to aggressively advertise the arbitration system, an arbitration institution has to appoint design experts as new arbitrators for domestic and international arbitration. Next, an arbitration institution needs to prepare the new and expediting rules with design field characterization. Finally, it has to plan to cooperate with all of the institutions and schools concerned.

In this study, the characteristics of gas-water relative permeability curves in a single fractured-plate according to the various aperture size were analyzed by using the Hele-Shaw type glass plate model. The plate was made of glasses for the observation of the two-phase flow pattern, and seven cases were set up based on the aperture size in the range of field scale from 30 to $120\mum$. The experiment was conducted by steady-state method, and the water saturation was determined more accurately by the developed digital image process technique. The empirical equations of relative permeability to gas and water for single fractured-plate were correlated by using the aperture size which directly affects the two-phase flow pattern and critical saturation.

Silicone is widely used for medical purposes in breast augmentation and other cosmetic procedures. Illegal injections of silicone in human beings might have adverse effects and one of the serious problems is a silicone embolism. We experienced five cases of unusual respiratory difficulties after an injection of liquid silicone in the breast, vagina, uterus, and hip. They were all young adult females, who were previously healthy. One of them died after the injection. The three remaining patients were admitted because of dyspnea, coughing, chest discomfort and bilateral pulmonary infiltration after the silicone injection. A transbronchial lung biopsy and autopsy disclosed many oil like materials filling the alveolar septal capillaries. Three patients underwent a computed tomogram (CT), which revealed multifocal airspace consolidations at the peripheral and nondependent portions of both lungs, which is a different finding from other thromboembolisms. Lung scans of the disclosed abnormalities were compatible with silicone induced pulmonary embolism.

A thromboembolic stroke is believed to be precipitated by a rupture of vulnerable atheromatous plaques. Until recently the assessment of a further risk of stroke in high-risk patients in whom atherosclerosis has presented with a transient ischaemic attack (TIA), has been confined to a quantitative assessment of the luminal patency of the internal carotid artery. These traditional stratification parameters are no longer believed to be the most accurate predictors of a thrombo-embolism. This is because the process of vessel wall remodeling can maintain a luminal patency, and consequently, quite large friable plaques may remain unidentified. Accordingly, there is a need for an improved risk assessment. The fibrous cap of a vulnerable plaque is thinner, and an intraplaque hemorrhage and inflammation can occur during the development of atherosclerotic plaque. Several imaging methods for identifying vulnerable plaques have been developed. Recently, high resolution magnetic resonance (MR) imaging has emerged as an accurate non-invasive tool that can characterize the carotid plaque components in vivo. A High resolution carotid magnetic resonance is capable of distinguishing an intact, thick fibrous cap from a thin and ruptured cap in carotid plaque. In addition, a plaque MR can identify the active inflammation and detect a hemorrhage. High resolution carotid MR imaging is a valuable noninvasive method for quantifying the plaque components and identifying vulnerable plaque.
