LZ4 is lossless compression algorithm, providing compression speed > 500 MB/s per core, scalable with multi-cores CPU. It features an extremely fast decoder, with speed in multiple GB/s per core, ...

Abstract: The rich spectral information within hyperspectral images (HSIs) results in large data volumes. Thus finding a compact representation for HSIs while maintaining reconstruction quality is a ...

This repository contains the source code and benchmarks for the paper ALP: Adaptive Lossless Floating-Point Compression, published at ACM SIGMOD 2024. ALP is a state-of-the-art lossless compression ...

Abstract: Both traditional and learning-based hyperspectral image (HSI) compression methods suffer from significant quality loss at high compression ratios. To address this, we propose a low-overhead, ...
