High Frequency Component Matching Motion Estimation: A Revolutionary Improvement for Real-Time Telemedicine Applications

In Telemedicine applications, for diagnostic purposes, it is essential that the video compression process causes no tangible loss of detail and introduces no noticeable artifacts which could be otherwise misinterpreted as being pathological in nature. On the other hand, due to the limitation of storage and transmission and the huge amount of medical video, high compression ratio is often required. Video coding exploits the high correlation between successive image frames to improve coding efficiency, which is achieved by motion estimation and motion compensation techniques. This paper demonstrates the feasibility of incorporating the high frequency component matching block motion estimation in H.264 in order to improve video compression performance in telemedicine applications. Implementation using the H.264 codec and thereby facilitating performance analysis, the experimental result indicates that high frequency component matching introduces a revolutionary improvement as a matching criterion for motion compensated predictive coding in real-time telemedicine applications.
