Global digital museum: multimedia information access and creation on the Internet

Multimedia information access on the Internet creates a new paradigm for museum information and education service that complements conventional school programs. We designed and developed the Global Digital Museum to permit easy access to the cultural heritage stored in museums around the world. The system provides a single virtual museum, enabling global search and edit of museum contents on the Internet. We applied the Global Digital Museum model to K-12 museum education by using real museum multimedia data. Technical issues addressed include: 1) unified and global access to heterogeneous and distributed multimedia contents of museums; and 2) interactive editing of the contents on the World-Wide Web. We describe the concept of Global Digital Museum, the system and network architecture, the data model for museum infomlation, and implementation of a prototype system on the Internet.

Fast accessing method of color image

This paper describes a method of indexing the color distribution of an image, which makes it easier to search for and access regions by their colors. The index has a quadtree structure with color indexes for successively divided image quadrants in its nodes. Thus the colors in each image quadrant are represented by a color index defined to take account of human visual perception. To perform a search, we descend through the index from a root, checking whether the color index is satisfying a condition. The nodes satisfying that condition correspond to image quadrants that contain the color being queried. Experimental result shows that this method is useful for detecting regions according to their colors in the early stages of the search process.

A Motion Picture Archiving Technique, and Its Application in an Ethnology Museum

This paper introduces database utilities for archiving motion pictures, and describes a prototype system called M-CIDB (Motion Color Image Data Base). There are two crucial problems in implementing motion picture archives: (1) scene indexing and database creation is time-consuming and error-prone, and (2) searching for scenes of interest is slow and awkward. The following techniques for solving the problems are proposed: (1) scene information structures including scene hierarchy and time-axis-based annotations for fast and random scene access, (2) automatic scene change detection and automatic representative frame image selection from all the original consecutive frame sequences, and (3) an interactive scene information editor for verifying and editing automatically detected scene information through a graphical user interface. A prototype system has been built and applied to an ethnology museum’s motion video in a preliminary feasibility study.

Applying Autonomic Computing with Open Standardized Resource Interface WSDM to Managing Multi-vendor IT Systems

As IT systems grow bigger and complex, they are comprised of many resources supplied by various vendors. Also, the Internet accelerates inter-enterprise business transactions and IT systems are connected each other. Consequently enterprise application systems are becoming a kind of large business process across multiple vendors. This transformation will also bring new type of complexity and difficulties to enterprise IT system management. Having awareness of these issues, IBM and Fujitsu have been collaborating on standardization effort for various areas of autonomic computing technologies. Autonomic computing and open standard interface are an effective approach to deal with these challenges. The initial areas of collaboration are common event format and interface for action to manage IT resources. hi this presentation, we show how an autonomic manager can solve these issues with using an open standard, WSDM (Web Service Distributed Management). We demonstrate the autonomic manager that behaves based on defined policy, continuously monitors systems, handles events and takes actions through WSDM interface in Multi-vendor IT Systems.
