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

Color Image Enhancement Algorithm Based on Nonsubsampled Contourlet Transform
: In this paper, a color image enhancement algorithm combined DCT transform and nonsubsampled contourlet transform was proposed. Since the difference of subband characteristics of nonsubsampled contourlet transform, different enhancement algorithms were
