基于小波优化的卷积自编码器地震道数据压缩
Convolutional autoencoder seismic trace data compression based on wavelet optimization
【摘要】 针对地震数据在压缩与重建过程中部分高频和峰值信息丢失的问题,结合小波变换(WT)在多分辨率分析中的优势和卷积自编码器(CAE)在特征提取和数据重建方面的高效能力,提出了一种基于WT改进CAE的地震道数据压缩方法。该方法构建了两个改进的CAE模型:低压缩比模型WTCAE-L,高压缩比模型WTCAE-H,实现了对地震数据的高效压缩,同时保持了较高的重建质量。实验结果表明,两者在各自压缩比范围内展现最佳性能。
【Abstract】 To address the issue of partial loss of high-frequency and peak information during the compression and reconstruction of seismic data, a seismic trace data compression method based on an improved convolutional autoencoder(CAE) enhanced by wavelet transform(WT) was proposed, leveraging the advantages of WT in multi-resolution analysis and the efficient capabilities of CAE in feature extraction and data reconstruction. Two improved CAE models were constructed using the method: a lowcompression-ratio model, WTCAE-L, and a high-compression-ratio model, WTCAE-H, which enabled efficient compression of seismic data while maintaining high reconstruction quality. Experimental results show that both models exhibit optimal performance within their respective compression ratio ranges.
