Delivery and Interactive Processing of Visual Data for A Cooperative Telemedicine Environment
Cooperative telemedicine environments are required for many situations such as consultations between residents and senior doctors, case correlations, and for teaching and research purposes. The mode of collaboration may vary with different situations, in terms of the synchronisation of tasks, the sharing of data and the extent of collaboration among participants. It is essential for participants to be able to remotely view and manipulate visual data (images, 2D and 3D graphics, animation and video) as well as interactively run application programs which involve visual data in real-time. However, this is not possible with current network bandwidth limitations when large amount of visual data are involved. In this paper, we first provide an analysis of functional requirements by participants in cooperative diagnosis in different types of situations, before discussing technical requirements, which form the basis for our system architecture design. A new approach is also presented for efficient handling of programs, which involve visual data in real time. This is achieved via the construction and transmission of small messages that encapsulate the operations in a pipelined or hierarchical fashion.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
