Progressive lossy-to-lossless coding of arbitrarily-sampled image data using the modified scattered data coding method

In earlier work, Demaret and Iske proposed the scattered data coding (SDC) method for (single-rate) coding of arbitrarily-sampled image data. In this paper, several modifications to the SDC method are proposed in order to remove some limitations of the original scheme, improve coding efficiency, and add a progressive lossy-to-lossless coding capability. Through experimental results, the proposed method is shown to yield a significant improvement in coding efficiency (relative to the original SDC method) as well as provide an efficient progressive lossy-to-lossless coding capability.
