“…This level-of-detail representation also allows for the creation of data compression methods, such as Zerotree encoders [34,26,38,46], that use wavelets to encode data such that the most important parts are encoded first, and the remainder of the data is encoded in order of decreasing importance. During decoding (or transmission) the process may be terminated at any point, and the reconstructed data is guaranteed to be the best possible given the amount of data transmitted.…”

Scientific computation is used for the simulation of increasingly complex phenomena, and generates data sets of ever increasing size, often on the order of terabytes. All of this data creates difficulties. Several problems that have been identified are (1) the inability to effectively handle the massive amounts of data created, (2) the inability to get the data off the computer and into storage fast enough, and (3) the inability of a remote user to easily obtain a rendered image of the data resulting from a simulation run. This dissertation presents several techniques that were developed to address these issues. The first is a prototype bin coder based on variable-tovariable length codes. The codes utilized are created through a process of parse tree leaf merging, rather than the common practice of leaf extension. This coder

“…Signed zeros present some difficulties when encoding. Some coding methods, such as those that use zerotrees and similar techniques [34,26,25,38,46], assume that the coefficients are centered around an unsigned zero. With signed zeros an explicit pass must be made to encode the signs.…”
