A Review of Subband Coding of Seismic
نویسندگان
چکیده
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 lter bank and frequency partitioning in the subband domain. In addition, a variable-rate seismic data sub-band coder system based on a non-adaptive hybrid uniform-nonuniform lter bank and sub-band block classiication as a common framework is evaluated. Favorable rate-distortion results are obtained with this method compared to results reported in the literature.

Subband Compression of Seismic Stack Sections
A subband lter bank is applied to decompose seismic stack sections. The lter bank is designed to give almost perfect reconstruction and maximum coding gain. A variable bit rate coding scheme is used on the sub-band signals. Blocks of subband samples are dynamically classiied into diierent classes according to the blockwise root mean-square value. Each subband sample is then quantized in a unifo...
متن کاملSubband Coding Methods for Seismic Data Compression∗
This paper presents a study of seismic data compression techniques and a compression algorithm based on subband coding. The algorithm includes three stages: a decorrelation stage, a quantization stage that introduces a controlled amount of distortion to allow for high compression ratios, and a lossless entropy coding stage based on a simple but efficient arithmetic coding method. Subband coding...

متن کاملFilter bank optimization for high-dimensional compression of pre-stack seismic data
A multi-dimensional variable-length subband coder for prestack seismic data was presented. A 2and 3-D separable near perfect reconstruction filter bank was optimized to maximize the coding gain, assuming that the correlation properties of pre-stack seismic data can be modeled by directional dependent autoregressive processes. Identical quantization and entropy coder allocation strategies were u...

Wavelet and subband coding have been shown eeective techniques for seismic data compression, especially when compared to DCT-based algorithms (such as JPEG), which suuer from blocking artifact at low bit-rates. The transforms remove statistical redundancy and permit eecient compression. This paper presents a novel use of the Generalized Lapped Orthogonal Transforms (GenLOTs) for compression of ...
