A simple shearlet-based reconstruction for computer tomography
Santiago Córdova, Daniel Vera
We find a new and simple inversion formula of the Radon transform RT with the only use of the shearlet system and of well-known properties of RT. No intertwining relation of differ…
Democracy of shearlet bases with applications to approximation and interpolation
Daniel Vera
Shearlets on the cone provide Parseval frames for . They also provide near-optimal approximation for the class of cartoon-like images. Moreover, there are spaces…
Greedy type algorithms for RIP matrices. A study of two selection rules
Eugenio Hernández, Daniel Vera
Some consequences of the Restricted Isometry Property (RIP) of matrices have been applied to develop a greedy algorithm called "ROMP" (Regularized Orthogonal Matching Pursuit) to r…
Shear Anisotropic Inhomogeneous Besov And Triebel-Lizorkin Spaces In
Daniel Vera
We define distribution spaces of a sequence of convolutions of a set of distributions with smooth functions, the shearlet system. Then, we define associated sequence spaces and pro…
Triebel-Lizorkin Spaces and Shearlets on the Cone in
Daniel Vera
The shearlets are a special case of the wavelets with composite dilation that, among other things, have a basis-like structure and multi resolution analysis properties. These relat…
Restricted non-linear approximation in sequence spaces and applications to wavelet bases and interpolation
Eugenio Hernández, Daniel Vera
Restricted non-linear approximation is a type of N-term approximation where a measure on the index set (rather than the counting measure) is used to control the number of terms…
