多通道生物医学信号的高效顺序压缩

Efficient sequential compression of multi-channel biomedical signals

Ignacio Capurro, Federico Lecumberry, Álvaro Martín, Ignacio Ramírez, Eugenio Rovira, Gadiel Seroussi

摘要:

本文提出了多通道生物医学信号的无损和近无损压缩算法。该算法是顺序的和有效的,这使得他们适合于低延迟和低功耗的信号传输应用。我们利用信息论和信号处理工具(如通用编码,通用预测,和快速在线实现的多元递归最小二乘法),结合简单的方法来利用空间以及时间冗余通常存在于生物医学信号。公开可用的脑电图和心电图数据库的算法进行测试,在所有情况下,超过了目前的最先进的近无损和无损压缩比。

英文摘要:

This work proposes lossless and near-lossless compression algorithms for multi-channel biomedical signals. The algorithms are sequential and efficient, which makes them suitable for low-latency and low-power signal transmission applications. We make use of information theory and signal processing tools (such as universal coding, universal prediction, and fast online implementations of multivariate recursive least squares), combined with simple methods to exploit spatial as well as temporal redundancies typically present in biomedical signals. The algorithms are tested with publicly available electroencephalogram and electrocardiogram databases, surpassing in all cases the current state of the art in near-lossless and lossless compression ratios.
