Abstract :
In this paper we study an optimal transmission mechanism along with a memory caching strategy in a server-client architecture for large JPEG2000 (J2K) images browsing. The system takes advantage on the scalability introduced by J2K codestreams. The idea is that users accessing the server could navigate in a seamless way in one or several images. They could change the displaying requirements, ask for a desired resolution, quality or region of interest (ROI) with no need to receive the whole codestream. We propose a smart data streaming strategy to minimize the latency time and support interactive browsing. Our strategy takes into account several constraints as delays, memory, bandwidth, etc., for permitting fast adaptation to image browsing with optimal employment of resources.
