The Curvelet Transform

open access: yesIEEE Signal Processing Magazine, 2010
Multiresolution methods are deeply related to image processing, biological and computer vision, and scientific computing. The curvelet transform is a multiscale directional transform that allows an almost optimal nonadaptive sparse representation of objects with edges.

Synthetic Aperture Radar Image Clustering with Curvelet Subband Gauss Distribution Parameters

open access: yesRemote Sensing, 2014
Curvelet transform is a multidirectional multiscale transform that enables sparse representations for signals. Curvelet-based feature extraction for Synthetic Aperture Radar (SAR) naturally enables utilizing spatial locality; the use of curvelet-based ...

Undergrowth Collagen Fibers Analysis by Fingerprint Enhancement Method. [PDF]

open access: yesBiol Cell
Collagen fibers detected and analysed by the fingerprint enhancement algorithm. ABSTRACT Collagen is a key protein in mammals that maintains structural integrity within tissues. A failure in fibrillar collagen reorganization can induce cancer or fibrosis formation, such as in spinal cord injury (SCI), where the healing process after the initial trauma ...

Recovering edges in ill-posed inverse problems: optimality of curvelet frames [PDF]

open access: yes, 2002
We consider a model problem of recovering a function $f(x_1,x_2)$ from noisy Radon data. The function $f$ to be recovered is assumed smooth apart from a discontinuity along a $C^2$ curve, that is, an edge.
