Abstract :
Based on 1-D continuous wavelet transformation (CWT) and 1-D discrete Fourier transformation (DFT), this paper develops 2-D wavelet-Fourier transformation, which can be used to analyze 2-D continuous-discrete signals and systems in wavelet-Fourier hybrid domain. The definitions and properties of this hybrid 2-D transformation are given in the paper. Also, the numerical algorithms of 2-D wavelet-Fourier transformation are developed for the hybrid 2-D signal processing
