Abstract: Multiresolution methods are deeply related to image processing, biological and computer vision, and scientific computing. The curvelet transform is a multiscale directional transform that ...

Abstract: In this paper, a robust watermarking scheme operating in curvelet domain is proposed. Curvelet transform directly take the edge as the basic representation element; it provides optimally ...

A digital image watermarking algorithm based on fast curvelet transform is proposed. Firstly, the carrier image is decomposed by fast curvelet transform, and, the watermarking image is scrambled by ...

An efficient, double-precision implementation of the Fast Discrete Curvelet Transform (FDCT) developed by Candès, Demanet, Donoho, and Ying, using the wrapping approach. The implementation is ported ...

ABSTRACT: Due to the development of CT (Computed Tomography), MRI (Magnetic Resonance Imaging), PET (Positron Emission Tomography), EBCT (Electron Beam Computed Tomography), SMRI (Stereotactic ...
