An efficient prefetching strategy for remote browsing of JPEG 2000 image sequences

摘要

This paper proposes an efficient prefetching strategy for interactive remote browsing of sequences of high resolution JPEG 2000 images. As a result of the inherent latency of client-server communication, the experiments of this study prove that a significant benefit, can be achieved, in terms of both quality and responsiveness, by anticipating certain data from the rest of the sequence while an image is being explored. This paper proposes a model based on the quality progression of the image in order to estimate which percentage of the bandwidth is dedicated to prefetch data. This solution can be easily implemented over any existing remote browsing architecture.
