Abstract :
An investigation is presented of transform-based seismic data compression. The study concentrates on discrete orthogonal transforms such as the discrete Fourier transform (DFT), the discrete cosine transform (DCT), the Walsh-Hadamard transform (WHT), and the Karhunen-Loeve transform (KLT). Uniform and subband transform coding schemes were implemented, and comparative results are given for data rates ranging from 150 to 550 b/s. These results are also compared to existing linear prediction techniques
