Telemedicine Aware Video Coding Under Very-Low Bitrates

摘要

Implementing a real-time telemedicine solution for remote areas using available technologies is a challenge due to limited or non-availability of high-bandwidth mediums at these areas. In this paper, we present a telemedicine aware video coding system based on the standard High Efficiency Video Coding (HEVC) codec. The HEVC codec provides much better coding efficiency at the expense of increased computational complexity, which we have dealt with by incorporating adaptive interpolation and selective quality enhancement techniques to achieve real-time performance. With our proposed telemedicine customized video coding system, we have been able to demonstrate sufficient diagnostic quality for two sets of diagnostic video sequences encoded at much lower bitrates i.e., 100 kb/sec.
