MULTI-RESOLUTION PERCEPTUAL ENCODING FOR INTERACTIVE IMAGE SHARING IN REMOTE TELE-DIAGNOSTICS
Javed Khan, D. Y. Y. Yun · 1996
This paper presents our research 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 constraints on various spatial patches of the transmitted video. The encoder, attached with a control mechanism, dynamically adjusts to the specifications with appropriate redistribution of spatial resolution and bit allocation. The proposed scheme does not require any new encoding/decoding algorithm to be designed rather it works with most existing ones. This novel scheme offers the viewer a new flexibility to efficiently manage the image resolution and the available bandwidth. 1.
