摘要
Abstract
Due to the particularity of the seismic data, they must be treated by lossless compression algorithm in some cases.In the paper, based on the integer wavelet transform, the lossless compression algorithm is studied. Comparingwith the traditional algorithm, it can better improve the compression rate. CDF (2, n) biorthogonal wavelet familycan lead to better compression ratio than other CDF family, SWE and CRF, which is owe to its capability in can-celing data redundancies and focusing data characteristics. CDF (2, n) family is suitable as the wavelet function ofthe lossless compression seismic data.关键词
