A progressive Lossless/Near-Lossless image compression algorithm
IEEE Signal Processing Letters, 2002A novel image compression technique is presented that incorporates progressive transmission and near-lossless compression in a single framework. Experimental performance of the proposed coder proves to be competitive with the state-of-the-art compression schemes.

Elf: Erasing-based Lossless Floating-Point Compression
Proceedings of the VLDB Endowment, 2023There are a prohibitively large number of floating-point time series data generated at an unprecedentedly high rate. An efficient, compact and lossless compression for time series data is of great importance for a wide range of scenarios. Most existing
