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 ...

Abstract: Summary form only given, as follows. We present approximate digital implementations of two new mathematical transforms, namely, the ridgelet transform and the curvelet transform. Our ...

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 ...

What is a curvelet transform? A curvelet is a mathematical building‑block, much like a wavelet but stretched, and directional, so it has an "orientation" that better represents images/signals which ...

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 ...

Empirical curvelet and ridgelet image fusion is an emerging technique in the field of image processing that aims to combine the benefits of both transforms. An empirical coefficient selection strategy ...

Automatic segmentation of the choroid on optical coherence tomography (OCT) images helps ophthalmologists in diagnosing eye pathologies. Compared to manual segmentations, it is faster and is not ...
