Lossless Compression Algorithms
Texts in Computer Science, 2014In this chapter, data compression as it relates to multimedia information is studied from the point of view of lossless algorithms, where the input data is essentially exactly recoverable from the compressed data Lossy algorithms, for which this is not the case, are presented in Chapter 8.

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

Lossless Compression of Event Camera Frames
IEEE Signal Processing Letters, 2022The letter introduces an efficient context-based lossless image codec for encoding event camera frames. The asynchronous events acquired by an event camera in a spatio-temporal neighborhood are collected by an Event Frame (EF).
