Low Bit-Rate Efficient Compression for Seismic Data

Abstract--Compression is a relatively new introduced tech-
nique for seismic data operations. The main drive behind the use
of data compression in seismic data is the very large size of seismic
data acquired. Some of the most recent acquired marine seismic
data sets exceed 10 Tbytes, and in fact there are currently seismic
surveys planned with a volume of around 120 Tbytes. Thus, the
need to compress these very large seismic data files is imperative.
Nevertheless, seismic data are quite different from the typical
images used in image processing and multimedia applications.
Some of their major differences are the data dynamic range
exceeding 100 dB in theory, very often it is data with extensive
oscillatory nature, the and directions represent different
physical meaning, and there is significant amount of coherent
noise which is often present in seismic data. Up to now some of the
algorithms used for seismic data compression were based on some
form of wavelet or local cosine transform, while using a uniform
or quasiuniform quantization scheme and they finally employ
