We describe a wavelet-based image compression system which has the following advantages: low-power utilization, low RAM requirements, embedded bit-plane compression, scalable decompression, and region-of-interest selectivity. These advantages are illustrated in an application to very high compressions of underwater camera images. The proposed system performs at a comparable level to a system based on the celebrated Daub 9/7 system, yet employing 256 times less RAM and a 16-bit dynamic range (with 8-bit images) instead of a 32-bit dynamic range.
