Image coding using the embedded zerotree wavelet algorithm
Jerome M. Shapiro · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1993
This paper analyzes the concept of zerotree coding in the context of successive approximation by considering a simple model for the interdependence of the wavelet coefficients corresponding to the same location at different scales and demonstrating why predicting insignificance across scales is easier than predicting significance.
