Embedded image coding using zerotrees of wavelet coefficients
IEEE Transactions on Signal Processing
The embedded zerotree wavelet algorithm (EZW) is a simple, yet remarkably effective, image compression algorithm, having the property that the bits in the bit stream are generated in order of importance, yielding a fully embedded code. The embedded code represents a sequence of binary decisions that distinguish a n image from the "null" image. Using a n embedded coding algorithm, a n encoder can terminate the encoding at any point thereby allowing a target rate or target distortion metric to bedoi:10.1109/78.258085 fatcat:zqylmsbccbf6ppdabqpkrde5ly
