  • Directional Complex-Wavelet Processing 

    Fernandes, Felix; van Spaendonck, Rutger; Burrus, C. Sidney (2000-08-20)
    Poor directional selectivity, a major disadvantage of the separable 2D discrete wavelet transform (DWT), has previously been circumvented either by using highly redundant, nonseparable wavelet transforms or by using ...
  • Phase and Magnitude Perceptual Sensitivities in Nonredundant Complex Wavelet Representations 

    Wakin, Michael; Orchard, Michael; Baraniuk, Richard G.; Chandrasekaran, Venkat (2003-11-01)
    The recent development of a nonredundant complex wavelet transform allows a novel framework for image analysis. Work on this representation has recognized that the phase and magnitude of complex coefficients can be related ...
