【摘要】 随着地震勘探研究的不断深入,地震资料的处理和解释量也越来越庞大,其中数据的冗余量也比较大。对这些数据进行合理的压缩处理已经成为一个重要的课题,本篇文章根据多分辨分析思想,用小波变换对地震数据进行多级分解得到多个子带,然后对每个子带做不同策略的量化和编码处理,仿真结果表明,这种压缩编码算法,既能得到期望的压缩比,而且压缩后的地震数据所带来的误差比单一的编码压缩算法要小很多。更多还原

【Abstract】 By the research of seismic explorer deeply,the disposal of seismic information and explanation become more and more huge.And there are quite considerable data are superfluous in it.The compression of these data is a important question for discussion.This thesis based on MRA idea.Using Wavelet Transform to decompose seismic data into several sub band.Then using a different quantized method and encoding.The simulation experimentation result shows that the arithmetic not only can receive anticipant compression ratio but also the error from which seismic compression is much smaller than single compression arithmetic.更多还原
