The Quincunx Filter-Based Sharp Frequency Localized Contourlet Transform for Image Denoising
The contourlet transform, one of the recent geometrical transform offers the two important features of anisotropy scaling law and directionality, but non-ideal filters are used which results in two important problems, first is the pseudo-Gibbs phenomena around singularities produced by the Laplacia...
