Super-resolution by Means of Beurling Minimal Extrapolation
Let M(T) be the space of complex bounded Radon measures defined on the ddimensional torus group (R/Z) = T, equipped with the total variation norm ‖ · ‖; and let μ̂ denote the Fourier transform of μ ∈ M(T). We address the super-resolution problem: For given spectral (Fourier transform) data defined on a finite set Λ ⊆ Z, determine if there is a unique μ ∈ M(T) for which μ̂ equals this data on Λ. W...
متن کاملExact Reconstruction using Beurling Minimal Extrapolation
We show that measures with finite support on the real line are the unique solution to an algorithm, named generalized minimal extrapolation, involving only a finite number of generalized moments (which encompass the standard moments, the Laplace transform, the Stieltjes transformation, etc.). Generalized minimal extrapolation shares related geometric properties with the basis pursuit approach o...
متن کاملSuper-resolution of Defocus Blurred Images
Super-resolution is a process that combines information from some low-resolution images in order to produce an image with higher resolution. In most of the previous related work, the blurriness that is associated with low resolution images is assumed to be due to the integral effect of the acquisition device’s image sensor. However, in practice there are other sources of blurriness as well, inc...
متن کاملA Collaborative Nonlocal-Means Super-resolution Algorithm Using Zernike Monments
Super-resolution (SR) with probabilistic motion estimation is a successful algorithm to circumvent the limitation of motion estimation upon conventional superresolution methods. However, the algorithm can’t match similar patches with rotation or scale. This paper presents an efficient improved algorithm by introducing Zernike moments as representation of image invariant features into similarity...
متن کاملSuper-Resolution Generalizing Nonlocal-Means and Kernel Regression
Super-resolution without explicit sub-pixel motion estimation is a very active subject of image reconstruction containing general motion. The Non-Local Means (NLM) method is a simple image reconstruction method without explicit motion estimation. In this paper we generalize NLM method to higher orders using kernel regression can apply to super-resolution reconstruction. The performance of the g...
