The algorithm was developed by Brazilian engineer Amir Said with William A. Pearlman in 1996.<ref name="Said"/>
== General description ==
The algorithm [[Code|code]]s the most important [[Wavelet transform|wavelet transform]] coefficients first, and transmits the bits so that an increasingly refined copy of the original image can be obtained progressively.
