【摘要】 对于“海量”的地震数据,一般压缩方法的效果不好。利用离散余弦变换编码和离散小波变换编码的联合压缩技术,对地震勘探数据进行了压缩处理,结果表明:本压缩方法能提高压缩比,保留更多的地震信号中细节信息,具有良好的压缩性能和很好的计算性能。联合压缩技术对于不同的地震数据压缩都有效果,但是压缩比不尽相同。更多还原

【Abstract】 The general compression way is not satisfied with the mass seismic data.The authors used united compression technique of discrete cosine transformation in combination with discrete wavelet transformation to compress seismic data.The results show that the compression ratio could be improved with more of preservations the minute information of seismic signals.Using this way is better in performance of compression and computing,and efficient for various seismic data,but it is different in the compression ratio.更多还原
