High-Ratio Lossy Compression: Exploring the Autoencoder to Compress Scientific Data

IEEE Transactions on Big Data, 2023
Scientific simulations on high-performance computing (HPC) systems can generate large amounts of floating-point data per run. As compared to lossless compressors, lossy compressors, such as SZ and ZFP, can reduce data volume more aggressively while maintaining the usefulness of the data.

High compression ratio image compression

1993 IEEE International Symposium on Circuits and Systems, 2002
An image compression method is proposed. It makes use of the wavelet transform (WT) with better frequency localization and the adaptive hierarchical vector quantization (AHVQ) technique. The WT provides a multifrequency channel representation for the image from which proper coding methods can be drawn.
