A Review of Subband Coding of Seismic Data

In this paper, the literature published on lossy compression of seismic data using the popular subband coding technique is reviewed. The strong links between subband coding, transform coding, and the more recent discrete wavelet transform coding are described. The performance of seismic data subband coding depends on the proper choice of filter bank and frequency partitioning in the subband domain. In addition, a variable-rate seismic data subband coder system based on a non-adaptive hybrid uniform-nonuniform filter bank and subband block classification as a common framework is evaluated. Favorable rate-distortion results are obtained with this method compared to results reported in the literature. 1. INTRODUCTION There are a number of methods for compression of seismic data that span the technology range from simple to sophisticated. The distinguishing feature of sophisticated technology is that it exploits the character of the data it intends to compress, resulting in a representat..
