MULTI-RESOLUTION PERCEPTUAL ENCODING FOR INTERACTIVE IMAGE SHARING IN REMOTE TELE-DIAGNOSTICS

This paper presents our r esearch on an interactive image transmission scheme for fast high resolution diagnostic medical video transmission. In this scheme, the viewer (or some other high level analytical or sensor mechanism) can specify either or both the maximum bit rate and the minimum quality c onstraints on various s patial patches of t he transmitted video. The e ncoder, attached with a control mechanism, dynamically adjusts to the specifications with app ropriate redistribution o f spatial resolution and bit allocation. The proposed scheme does not require any new encoding/decoding a lgorithm to b e designed rather it works with most existing ones. This novel scheme offers the v iewer a n ew flexibility to efficiently manage the image resolution and the available bandwidth.
