Embedded zerotree runlength wavelet image coding
Jianhua Wu, C Olivier, Christian Châtellier · 2002
This paper presents a simple and effective image coding technique: the embedded zerotree runlength wavelet (EZRW) image coding algorithm. The main idea behind EZRW is making use of the correlation among the data output by dominant pass and subordinate pass in the embedded zerotree wavelet (EZW) image encoding process. With this algorithm, the compression ratio is better than the EZW algorithm and comparable with that of the SPIHT algorithm for most test images.
