Curvelets, multiresolution representation, and scaling laws
Emmanuel J. Candès, David L. Donoho · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2000
Curvelets provide a new multiresolution representation with several features that set them apart from existing representations such as wavelets, multiwavelets, steerable pyramids, and so on. They are based on an anisotropic notion of scaling. The frame elements exhibit very high direction sensitivity and are highly anisotropic. In this paper we describe these properties and indicate why they may be important for both theory and applications.
