Multi-linear Generalised Radon Transforms 2
holds for all open sets U ⊆ Σ in a sufficiently small neighbourhood of the origin. We have already seen that (1) holds for non-trivial values of p only if the family Xπ of associated vector fields satisfies the Hörmander condition. A deeper fact is that the converse of this statement is true. This converse may be expressed in a very precise fashion which relates the range of Lebesgue exponents ...
متن کاملTransversal Multilinear Radon-like Transforms: Local and Global Estimates
We prove local “Lp-improving” estimates for a class of multilinear Radon-like transforms satisfying a strong transversality hypothesis. As a consequence, we obtain sharp multilinear convolution estimates for measures supported on fully transversal submanifolds of euclidean space of arbitrary dimension. We also prove global estimates for the same class of Radon-like transforms under a natural ho...
متن کاملShot interpolation for radon multiple suppression
Decreased CMP fold, such as that found in multi-source, multi-streamer acquisition geometries, can hinder processing steps which benefit from well sampled CMP gathers, such as radon transforms. In two steps of linear least squares, multiscale prediction-error filters (PEF)s can estimate local dips from the recorded data and then use the dip information to fill in unrecorded shot or receiver gat...
متن کاملRadon Transforms on Affine Grassmannians
We develop an analytic approach to the Radon transform f̂(ζ) = ∫ τ⊂ζ f(τ), where f(τ) is a function on the affine Grassmann manifold G(n, k) of k-dimensional planes in Rn, and ζ is a k′-dimensional plane in the similar manifold G(n, k′), k′ > k. For f ∈ Lp(G(n, k)), we prove that this transform is finite almost everywhere on G(n, k′) if and only if 1 ≤ p < (n− k)/(k′− k), and obtain explicit inv...
متن کاملGeneralised relaxed Radon transform (GR2T) for robust inference
This article introduces the Generalised Relaxed Radon Transform (GR2T) as an extension to the Generalised Radon Transform (GRT) [1]. This new modelling allows us to define a new framework for robust inference. The resulting objective functions are probability density functions that can be chosen differentiable and that can be optimised using gradient methods. One of this cost function is alread...
