局域波自适应时频分析是处理非平稳数据较为有效的新方法.该文较系统地研究了局域波分析的瞬时频率估计、分解的物理意义、高于小波分析的时频分辨率、没有Wigner-Ville时频分布交叉项和分解二维图像的特性.

Adaptive Local Wave Analysis (LWA) is a new effective method for processing non-stationary data.In this paper

the characteristics of the LWA

such as the physical meaning of the intrinsic mode functions

instantaneous frequency

having better joint time-frequency resolution than Wavelet Analysis

without cross terms that exist in Wigner-Ville distribution analysis

and 2-dimension LWA application in image processing

are discussed.
