Abstract

We develop a second-generation subband image coding algorithm which exploits the pyramidal structure of transform-domain representations to achieve variable-resolution compression. In particular, regions of interest within an image can be selectively retained at higher fidelity than other regions. This type of coding allows for rapid, very high compression, which is especially suitable for the timely communication of image data over bandlimited channels.
