Pattern Recognition in SAR Images using Fractional Random Fields and its Possible Application to the Problem of the Detection of Oil Spills in Open Sea
Agustín Mailing, Segundo A. Molina, José L. Hamkalo +5
In this note we deal with the detection of oil spills in open sea via self similar, long range dependence random fields and wavelet filters. We show some preliminary experimental r…
Convergence of -Stable Random Fractional Wavelet Series and Some of its Properties
Juan M. Medina, Fernando R. Dobarro, Bruno Cernuschi-Frías
For appropriate orthonormal wavelet basis , constants and , if denotes the Riesz fractiona…
Sampling basis in reproducing kernel Banach spaces
Hernán D. Centeno, Juan M. Medina
We present necessary and sufficient conditions to hold true a Kramer type sampling theorem over semi-inner product reproducing kernel Banach spaces. Under some sampling-type hypoth…
H-Regular Borel measures on locally compact abelian groups
Lutz Peter Klotz, Juan Miguel Medina
Let be an LCA group, a closed subgroup, the dual group of . In accordance with analogous notions in prediction theory the classes of -regular and -sing…
Density of spaces of trigonometric polynomials with frequencies from a subgroup in -spaces
Juan Miguel Medina, Lutz Peter Klotz, Manfred Riedel
Let be an LCA group, a closed subgroup, the dual group of and be a regular finite non-negative Borel measure on . We give some necessary and…
