Compactly Supported Shearlets
Shearlet theory has become a central tool in analyzing and representing 2D data with anisotropic features. Shearlet systems are systems of functions generated by one single generator with parabolic scaling, shearing, and translation operators applied to it, in much the same way wavelet systems are dyadic scalings and translations of a single function, but including a precise control of directio...
متن کاملCompactly Supported Distributions 803
In this note, we present results on the representation of any compactly supported distribution by a nite linear combination of linearly independent integer translates of distributions. As an application we obtain a self-adaptive stability lemma.
متن کاملCompactly supported cohomology of buildings
Suppose (W,S) is a Coxeter system. A subset T ⊂ S is spherical if it generates a finite subgroup of W . S denotes the poset of spherical subsets of S. Let Φ be a building in the sense of [6] (i.e., Φ is a set of chambers, equipped with a family of adjacency relations indexed by S and a W -valued distance function, Φ×Φ→W ). Let A denote the set of finitely supported Z-valued functions on Φ (i.e....
متن کاملConstruction of compactly supported affine frames
Since the publication, less than ten years ago, of Mallat’s paper on Multiresoltion Analysis [Ma], and Daubechies’ paper on the construction of smooth compactly supported refinable functions [D], wavelets had gained enormous popularity in mathematics and in the application domains. It is sufficient to note that there are currently more than 10,000 subscribers to the monthly Wavelet Digest. At t...
متن کاملCompactly Supported Orthogonal Symmetric Scaling Functions
Daubechies 5] showed that, except for the Haar function, there exist no compactly supported orthogonal symmetric scaling functions for the dilation q = 2. Nevertheless, such scaling functions do exist for dilations q > 2 (as evidenced by Chui and Lian's construction 3] for q = 3); these functions are the main object of this paper. We construct new symmetric scaling functions and introduce the \...
