LZ-based image compression

We review some of our recent work on LZ-based, single-pass, adaptive algori thms for the compression of digital images. Our approach combines dictionar y techniques from adaptive lossless text compression with quantization tech niques to obtain single-pass, highly adaptive compression algorithms that a llow the compression-fidelity tradeoff to be continuously adjusted, and len d themselves to high-speed parallel/hardware implementation.
