摘要

本文描述了基于临床相关提取信息的第二代小波和提升结构的心脏信号分析。信息提取可以通过不同的谱(如多重分形)和谱图(时频)表示来完成。在这里，新奇之处主要与心音图的知识控制分析和降噪有关。我们建议自适应(依赖于信号的)基于小波的处理能够同时保留相关的高频细节并降低噪声。

Second generation wavelets: Advantages in cardiosignal processing

In this paper, the cardiosignal analysis using second generation wavelets and lifting structure based on clinically-relevant extracted information is described. The information extraction can be performed by different spectral (such as multifractal) and spectrogram (time-frequency) representations. Here, the novelties are related mainly to the knowledge-controlled analysis and noise reduction in phonocardiograms. We suggest adaptive (signal-dependent) wavelet-based processing able to simultaneously preserve relevant high-frequency details and reduce noise.
