Fast seismic data compression based on high‐efficiency SPIHT

Abstract

Based on the set positioning in hierarchical tree (SPIHT) algorithm, fast seismic data compression based on the high‐efficiency SPIHT (HESPIHT) algorithm is presented. To verify the validity of the algorithm, 10 seismic cross‐sections are selected for the experiment. The result shows that the algorithm can reserve the quality of data better, meanwhile improving the efficiency of encoding and decoding.
