They all are snr scalable, and, especially ebcot is resolution scalable. these properties are essential in transmission of image on internet. because the performance of an entropy coder can be significantly improved by having the coder dynamically adapt to the current " context ", context models also have widely been adopted in image compression
基於小波的圖像壓縮已成為圖像壓縮研究的主流，一些小波系數模型也隨之產生，如ezw 、 spiht和用於jpeg2000的ebcot ，這三種模型都具有snr可擴展性質，其中ebcot還具有解析度可擴展性質。
