A Technique For Lossless Compression Of Seismic Data

Abstract

This paper presents a novel and effective approach for lossless compression of seismic data. The lossless compression algorithm consists of two stages. The first stage is a modified linear predictor with discrete coefficients and the second stage is a bi-level sequence coding scheme in which two sample sizes are chosen and the predictor residue sequence is encoded into subsequences that alternate from one level to the other. The key feature of the two-stage algorithm is that it provides exact, bit for bit reconstruction of the original data, without any numerical noise added during decompression.
