Practical band-limited extrapolation relying on Slepian series and compressive sampling
We consider a rather simple algorithm to address the fascinating field of numerical extrapolation of (analytic) band-limited functions. It relies on two main elements: namely, the lower frequencies are treated by projecting the known part of the signal to be extended onto the space generated by “Prolate Spheroidal Wave Functions” (PSWF, as originally proposed by Slepian), whereas the higher one...
متن کاملSuper-Resolution Using Sub-Band Self-Similarity
A popular approach for single image super-resolution (SR) is to use scaled down versions of the given image to build an internal training dictionary of pairs of low resolution (LR) and high resolution (HR) image patches, which is then used to predict the HR image. This self-similarity approach has the advantage of not requiring a separate external training database. However, due to their limite...
متن کاملLearned Spectral Super-Resolution
We describe a novel method for blind, single-image spectral super-resolution. While conventional superresolution aims to increase the spatial resolution of an input image, our goal is to spectrally enhance the input, i.e., generate an image with the same spatial resolution, but a greatly increased number of narrow (hyper-spectral) wavelength bands. Just like the spatial statistics of natural im...
متن کاملSuper-Resolution Using Sub-band Constrained Total Variation
Super-resolution of a single image is a severely ill-posed problem in computer vision. It is possible to consider solving this problem by considering a total variation based regularization framework. The choice of total variation based regularization helps in formulating an edge preserving scheme for super-resolution. However, this scheme tends to result in a piece-wise constant resultant image...
متن کاملOn the Extrapolation of Band-Limited Functions with Energy Constraints
Abstruct-A modification of the algorithm proposed by Papoulis and Gerchberg for extrapolating band-limited functions’ is suggested to extend its applicability over data corrupted by noise. We assume that energy constraints are known either for the band-limited signal or for the noise. In addition, the discrete formulation of the iterative algorithm is derived, and the transition from the con...
