Directional Wavelets Revisited: Cauchy Wavelets and Symmetry Detection in Patterns
The analysis of oriented features in images requires two-dimensional directional wavelets. Among these, we study in detail the class of Cauchy wavelets, which are strictly supported in a (narrow) convex cone in spatial frequency space. They have excellent angular selectivity, as shown by a standard calibration test, and they have minimal uncertainty. In addition, we present a new application of...
متن کاملWavelets, Ridgelets and Curvelets revisited
A recently developed new approach, called “Empirical Wavelet Transform”, aims to build 1D adaptive wavelet frames accordingly to the analyzed signal. In this paper, we present several extensions of this approach to 2D signals (images). We revisit some well-known transforms (tensor wavelets, Littlewood-Paley wavelets, ridgelets and curvelets) and show that it is possible to build their empirical...
متن کاملDirectional Wavelets on the Sphere
In this paper we propose a construction of directional wavelets on the sphere. We make use of the Euclidean Limit defined in [1] for lifting up to ¥ § ¦ usual directional wavelets in¨© ¦. We finally discuss implementation issues and potential applications.

Directional spin wavelets on the sphere
We construct a directional spin wavelet framework on the sphere by generalising the scalar scale-discretised wavelet transform to signals of arbitrary spin. The resulting framework is the only wavelet framework defined natively on the sphere that is able to probe the directional intensity of spin signals. Furthermore, directional spin scale-discretised wavelets support the exact synthesis of a ...
