摘要: 引入基于正交小波基的多尺度分析,并将其用于色谱/光谱二维数据压缩和消除复杂背景影响的研究.结果表明,该法不但成功地消除了复杂的色谱/光谱背景干扰,而且能同时大幅度地压缩数据量.对模拟和实际体系的应用均获得满意的结果.

关键词: 多尺度分析, 小波变换, 数据压缩, 色谱/光谱背景, 秩图

Abstract: In this paper, multiresolution analysis(MA) based on orthonormal wavelet basesis introduced.Its applications in data compression and background eliminatlon of hyphenatedchromatographic data are discussed.The results show the proposed method can remove theinfluence of complex background successfully as well as compress data efficiently.Satisfacto-ry results from computer simulation and real analytical systems are achieved.
