Abstract
In this paper, we present a region-based scalable coding technique that can be used in interactive image/video communications. This method has a capability of near lossless coding for a specific region of interest (ROI), while the rest of the region is coded with high quality lossy codec. There are many potential applications of the region-based scalable video coding method in the areas of interactive communications such as storm tracking, wild fire and air traffic monitoring using satellite still images and near real time video sequences. It enables the server/client system to reduce data traffic across the networks while the quality of a specific area of interest chosen for each client's needs is still satisfied. We tested this technique by applying it to still images and traffic monitoring image sequences. The results consistently show high level of performance.
