Abstract—The CONTOURLET transform is a new two-dimensional
extension of the wavelet transform using multiscale and direc-
tional fi lter banks. The CONTOURLET expansion is composed of
basis images oriented at various directions in multiple scales,
with fl exible aspect ratios. Given this rich set of basis images,
the CONTOURLET transform effectively captures smooth contours
that are the dominant feature in natural images.
