| Abstract: | Application in scientific computing often operate with large volume of output and input data, the space required for data storage and data transfer over communication networks are bottleneck in scientific computing. In the paper,we present a compression method based on optimized prediction operator which applied to structured scientific data.the proposed approach may be used both for lossy and lossless compression and is well suited for scalar fields. Numerical results indicate that our method successfully outperforms universal compression algorithm greatly. |
