A multimedia perioperative record keeper for clinical research.

Abstract: Objective. To develop a multimedia perioperative recordkeeper that provides: 1. synchronous, real-time acquisition of multimedia data, 2. on-line access to the patient's chart data, and 3. advanced data analysis capabilities through integrated, multimedia database and analysis applications.Design. To minimize cost and development time, the system design utilized industry standard hardware components and graphical software development tools. The system was configured to use a Pentium PC complemented with a variety of hardware interfaces to external data sources. These sources included physiologie monitors with data in digital, analog, video, and audio as well as paper-based formats.Development. The development process was guided by trials in over 80 clinical cases and by the critiques from numerous users. As a result of this process, a suite of custom software applications were created to meet the design goals. ThePerioperative Data Acquisition application manages data collection from a variety of physiological monitors. TheCharter application provides for rapid creation of an electronic medical record from the patient's paper-based chart and investigator's notes. TheMultimedia Medical Database application provides a relational database for the organization and management of multimedia data. TheTriscreen application provides an integrated data analysis environment with simultaneous, full-motion data display.Conclusion. With recent technological advances in PC power, data acquisition hardware, and software development tools, the clinical researcher now has the ability to collect and examine a more complete perioperative record. It is hoped that the description of the MPR and its development process will assist and encourage others to advance these tools for perioperative research.

Context-based Multimedia Content Management Framework and Its Location-aware Web Applications

Abstract: This paper treats a context-based multimedia content management system (MCMS), whose various types of contents are easily gathered from everywhere at anytime using mobile phones, and stored in a web server as a multimedia database. In this paper, the authors propose the framework of software components for developing location-aware web applications that use multimedia contents stored in the multimedia database on the web server. The authors also introduce several practical location-aware web applications, e.g., Google Maps based Sight-seeing information system, Google Maps based web Natural Science Dictionary, etc. that are already developed using the proposed components. One of the prospective applications of the proposed framework is Google Maps based Life-log system. Data stored by a lot of users using their mobile phones are regarded as their Life-log data because the data includes location data by GPS, date/time data, other related multimedia data such as picture images, movies, recorded sounds and texts. By analyzing them using any data-mining methods, it is possible to extract activity patterns of the users those are very useful for various web services like recommendation systems. As a theoretical aspect of the paper, the authors discuss data analyzing techniques to be used in the proposed framework.

A multiresolution representation scheme for multimedia databases

Abstract: We present a compression scheme that is useful for interactive video applications such as browsing a multimedia database. The focus of our approach the development of a compression scheme (and a corresponding retrieval scheme) that is optimal for any data rate. To browse a multimedia database, such a compression scheme is essential. We use a multiresolution setting, but eliminate the need for wavelets. This results in much better compression. We show experimental results and explain in detail how to extend our approach to multidimensional data.

A Context-Based Whole Video Retrieval System with Dynamic Video Stream Analysis Mechanisms

Abstract: With the rapid expansion of fictional video contents on WWW, it is important to develop video retrieval mechanisms for fictional video contents, such as TV drama, animations, and movies. This paper proposes a context-based video retrieval system for retrieving an entire video stream, not individual scenes or fragments. The unique feature of this system is a SQL-like contextual multimedia query language, which allows users to express and characterize their queries by using video clips as contexts. It extracts emotive contexts of visual elements from video files by analyzing the color-emotions hidden within video content using methods developed during color psychology research. The system’s capabilities enables new ways of querying artistic, visually rich and dynamic video content – something which is not possible by using just a few words. This is done by inspecting the dynamic and time-evolving contexts of video data. A prototype system has been implemented which is applicable to performing queries against television content. This paper clarifies the feasibility of the system by demonstrating the results of several experiments.

Method and apparatus for operating a contact center system

Abstract: The invention discloses a contact center that is commonly used by a number of companies that can be contacted by their clients using multiple media (e.g. voice, instant messging, email) that can be connected via phone networks or the internet. Each company using the contact center maintains their own customer relationship management (CRM1, CRM2) data. The CRM data is uploaded from the plurality of companies into a multimedia database (CTI database 270). The uploading includes transforming the CRM data from an original format maintained by each of the companies into a standardized format for the multimedia database (CTI database 270, 480). Communications sessions can then be handled by the contact center (i.e. by using the CTI server 80 and switch 90) using the CRM data in the multimedia database (CTI database 270).
