SPIHT-based Image Archiving Under Bit Budget Constraints

Abstract

Image archiving is important in various applications. In this work, we formulate the problem of compressing image archives as an optimization problem and present an efficient method for solving this problem. Our method is based on adapting SPIHT to image archiving where the total bit budget is distributed optimally across the images. We show experimentally that this method significantly outperforms its counter-part, namely, SPIHT with equal distribution of bit budget.
